, Artificial neural networks to control the wavelength and peak intensity of a DFB laser diode emission
In this work a methodology for estimating the operating current and temperature of a distributed feedback (DFB) laser required to get an emission with particular central wavelength and peak intensity is presented. It is based on an ensemble of six artificial neural networks (ANNs), in which their inputs are the target wavelength and peak intensity, and their outputs are the operating current and temperature of the DFB laser. Here, ANNs can establish non-linear relationships between the temperature and current of the laser with the wavelength and intensity of its emissions. Moreover, it is shown by experimental results that the operating DFB laser diode current and temperature are correctly estimated by our algorithm, since the emission obtained achieved, with high precision, the target central wavelength and peak intensity. Finally, with the proposed methodology it is possible to implement, in practically any research lab, a precise control system for establishing the central wavelength and peak intensity of an emission by setting the current and the temperature of the thermoelectric cooler of a DFB laser diode.

High pulse energy, low-alignment sensitivity master-oscillator power-amplifier (MOPA) systems enable portable long range laser devices. Comprehensive amplifier modelling is an essential tool in producing efficient, optimised amplfication capable of producing high pulse energies. This paper outlines the development of a large-mode, low-alignment sensitivity neodymium yttrium aluminium garnet (Nd:YAG) (MOPA) system, achieving a total output pulse energy of 265 mJ with an optical efficiency of 18%. A Q-switched diode-pumped Nd:YAG zig-zag oscillator is developed with an output pulse energy of 98 mJ and slope efficiency of 31%. Through the use of an intracavity aperture, the beam quality exhibited an M
of 4.3 and 4.6 and far field divergence of 1.3 mrad and 1.2 mrad in the horizontal and vertical, respectively. The oscillator output is amplified within a diode-pumped Nd:YAG zig-zag amplifier with a system amplification of 2.8. Comprehensive amplifier modelling based on a Frantz-Nodvik analysis is demonstrated, with the saturation characteristics suggesting a route to further energy enhancement and highlighting the necessity for amplifier modelling in high energy system design.

We have effectively developed a formaldehyde concentration sensor based on an optical fiber displacement sensor. Two distinct approaches based on displacement tuning and reflection spectrum measurement in combination with a UV light source were used to test our sensor. The UV–visible light source (OSL 2 Thorlabs) was used to illuminate the sample, and the power output of the backscattered radiation dropped linearly with the formaldehyde concentration. The sensor we tested showed remarkable sensitivity, linearity, and stability in measuring formaldehyde concentrations between 0% and 5%. The displacement tuning scheme achieved a sensitivity of 0.031
W/% with a linearity of 91%, whereas the reflection method exhibited a sensitivity of 2634.3 counts/% and a linearity of 98%. Furthermore, our sensor is non-contact, shielding the sample and probe from danger and damage. These findings show that our fiber bundle sensor has the potential to be a suitable instrument for tracking formaldehyde concentrations in the future for applications related to food safety.

Surface plasmon resonance (SPR) has become an important optical biosensing technology due to its real-time, label-free, and noninvasive nature. These techniques allow for rapid and ultra-sensitive detection of biological analytes, with applications in medical diagnostics, environmental monitoring, and agriculture. SPR is widely used in the detection of biomolecular interactions, and improvements are required for both sensitivity and
in vivo
uses for practical applications.
In this study, we developed an SPR biosensor to provide a highly sensitive and specific approach to early-stage detection of viral and malignant diseases, such as cancer tumors, for which biomarker detection is very important. A cancer cell line (HeLa cells) with biomarker Rodamine 6G was experimentally analyzed
in vitro
with our constructed SPR biosensor. It was observed that the biosensor can offer a potentially powerful solution for tumor screening with dominant angular shift. The angular shift for both regents is dominant with a time curve at a wavelength of 632.8 nm of a He–Ne laser. We have successfully captured and detected a biomarker
in vitro
for cancer diagnostics using the developed instrument.

, Photon counting based pump-probe technique for quantitative characterization of fluorescence in a lock-in free detection manner
The stimulated emission (SE) signal in pump-probe experiment is conventionally measured with lock-in detection to differentiate the weak signals from the relatively large background of spontaneous emission and probe beam. Therefore, direct characterization of signal strength are often major limiting factors in terms of noise, speed, and data acquisition. In contrast, photon counting allows direct quantification of signal strength, while synchronized pump-probe pulse enables precise timing and the separation of signals accordingly. Herein, the SE based pump-probe method is combined with time-correlated single-photon counting to investigate the ultrafast photochemical parameters, digitally and quantitatively. As a proof-of-concept, our technique is applied to investigate, fluorescence lifetime
, optical absorption cross-section
, and the SE cross-section
, of a fluorescent dye (ATTO 647N) quantitatively. The experimental results are also compared with theoretical photon statistics to further justify the advantages including experimental and statistical critical molecular dynamics parameters extraction with excellent high accuracy.

, Chaotic semiconductor laser systems—bandwidth enhancement predicted by numerical simulations
Numerical simulations using a traveling wave model are used to predict the radio frequency (rf) bandwidth and relative total rf power of chaotic output from a semiconductor laser (SL) with a delayed optical feedback system. By tailoring the linewidth enhancement factor (LEF) and nonlinear gain compression of the SL, improvements of a factor of two in the 80%-of-the-rf-power bandwidth, five in the rf bandwidth above 40 dB, and ten in the integrated rf power of the chaos, compared to values for a commercial-like SL, are predicted to be possible. The SL parameter values to be targeted will require device designers and fabricators to explore ways to decrease relaxation oscillation damping while, preferably, still achieving a high relaxation oscillation frequency. Higher values of LEF are a feature of poorer quality SLs of the past and can be expected to be achieved by reversion to past device recipes.

The purpose of this paper is to further investigate the correlated and memory effects in 3D-Pauli-like noisy channels for controlled teleportation of an arbitrary unknown single-qutrit state. We first construct a three-qutrit maximally entangled state in a three-dimensional (3D) Hilbert space and subsequently propose a 3D controlled quantum teleportation (CQT) scheme for an arbitrary unknown single-qutrit state using the constructed three-qutrit maximally entangled state as the quantum channel. In this ideal case, through a few simple 3D unitary operations, the two communicating parties can perfectly accomplish the teleportation task under the supervision of the controller. Subsequently, we examine the performance of this CQT scheme under two successive uses of a 3D-Pauli-like noisy channel with memory, where the noise errors are categorized into four types: trit-flip, t-phase-flip, trit-phase-flip, and t-depolarizing. For each noise type, an analytical expression of the average fidelity is derived as a function of both the noise and memory parameters. Specifically, we find that, regardless of the noise strength, memory enhances the average fidelity for trit-flip and t-depolarizing noises, whereas for t-phase-flip and trit-phase-flip noises, memory reduces the average fidelity once the noise intensity exceeds a certain threshold. This indicates that in the first two noisy channels, memory can improve the communication efficiency of CQT, while in the latter two, excessive noise causes memory to diminish the teleportation performance.

When two electrons are emitted from a metal needle tip with the help of femtosecond laser pulses, they show a strong anticorrelation signal in the energy domain. Depending on the wavelength and intensity of the driving laser pulses, the electron emission process can be either in a perturbative regime, like single- or multi-photon photoemission, or in the strong-field regime, where emission is dominated by the instantaneous electric field of the laser pulse, or in the intermediate regime. Here, we report on the two-electron anticorrelation signal and how it evolves from the multiphoton toward the strong-field emission regime. We show that in both cases, the resulting anticorrelation signal can be well explained by semi-classical simulations using a point-particle model, thus the dynamics is dominated by the center-of-mass dynamics of the individual electrons. However, the actual emission process of multiple interacting electrons requires improved quantum mechanical models and therefore remains the subject of future work.

We investigate the band structure in a nonreciprocal Su–Schrieffer–Heeger (SSH) lattice that incorporates both nearest-neighbor and next-nearest-neighbor (NNN) couplings. Our analysis demonstrates that NNN coupling gives rise to distinctive dangling modes, which emerge when the intracell coupling strength predominates over the intercell coupling. Consequently, the energy levels of edge modes in the topologically nontrivial regime exhibit a dependence on structural parameters. Notably, increasing the nonreciprocal strength lifts the degeneracy of these dangling modes, while enhancing the long-range coupling restores their degeneracy. These findings indicate that the interplay between long-range and nonreciprocal couplings provides a powerful means to control the spatial localization of edge modes and the characteristics of the non-Hermitian skin effect. Experimentally, we achieve nonreciprocal NNN coupling in a zigzag array of optical microring resonators by adiabatically eliminating a dissipative auxiliary mode in a three-mode system, enabling tunable asymmetric coupling through phase modulation. Our results underscore the crucial role of long-range coupling in reshaping band structure and topological features of nonreciprocal SSH systems.

The cubic phase state constitutes a nonlinear resource that is essential for universal quantum computing protocols. However, constructing such non-classical states faces many challenges. In this work, we present a protocol for generating a cubic phase state with high fidelity. The protocol is based on a set of Gaussian operations assisted by a detection operation. To find the proper set of parameters that results in both high fidelity and high detection probability, we provide a numerical multiparameter optimization. We investigate a broad range of target states and study how parameter imperfections influence fidelity.

This paper presents a high-performance mid-infrared laser and its application in spectroscopic gas detection. A ring-cavity continuous-wave optical parametric oscillator (OPO) based on MgO:PPLN was constructed, with a signal wavelength tuning range covering 1.3–1.9
m and an idler wavelength tuning range covering 2.4–4.7
m. The linewidth reached the MHz level, while the wavelength and power stability reached the pm level and below 1.3% RMS, respectively. Utilizing cantilever-enhanced photoacoustic spectroscopy to detect photoacoustic signals induced by periodically amplitude-modulated light, sensitive detection of CO₂ and CH₄ over a wide wavelength range was achieved, with a detection sensitivity reaching the sub-ppb level. The results indicate significant application prospects for high-performance OPOs in gas detection.

This study investigates the possibility of realizing a relativistic strophotron free electron laser (RS FEL) with a special focus on the stability of electron motion in such systems. As a hard problem, the FEL problem presents the challenge of creating electromagnetic tunable coherent radiation in a wide wavelength range, especially in the THz and x-ray ranges. This paper deals with the realization of a relativistic strophotron FEL. The optimal configuration of magnets has been identified, which achieves stable movement of electrons in relativistic strophotron. The results are applied to the periodicity of beam motion in both transverse directions to achieve the conditions for RS FEL realization. The research findings suggest that using a special configuration of magnets can contribute to the optimization of the relativistic strophotron making movement of an electron beam, which is stable and useful for the creation of RS FEL. We highlight the creation of an RS FEL, compare it with the usual undulator (see below) and point out the advantage of an RS FEL under certain conditions. A scheme with quadrupole lenses is presented for the realization of a relativistic strophotron type free electron laser. The presented scheme provides electron stability in the transversal direction. The equations of motion are solved and the trajectories are found. It is shown that the motion of electrons in the proposed scheme is stable in both transverse directions.

In this letter, we propose a new model based on an optomechanical system to control the spatial properties of the dispersion spectrum of a weak cavity field. The optomechanical cavity consists of a three-level atomic system with ladder-type configuration. The atomic system interacts with the composite vortex light and a weak cavity field. The composite vortex light carries an orbital angular momentum (OAM), which can be used to adjust the spatial properties of the medium. We found that by controlling the OAM number of the composite vortex light, the spatial pattern of the dispersion spectrum can be controlled in different regions of space. By adjusting the dispersive control of the medium, the refraction and group indices can be optimized for application in quantum information processing.

Photobiomodulation (PBM) based on low-power lasers is used worldwide as a non-pharmacological therapeutic approach to treat diseases and clinical conditions. Although some studies have reported PBM for the treatment of breast lymphedema and radiodermatitis, there is a lack of evidence regarding its adverse effects on mammary epithelial cells, such as deregulated cell proliferation and oxidative stress of mammary epithelia. Thus, we aimed to examine the biological effects of laser-based PBM on the cellular viability, proliferation, and oxidative stress levels of mammary epithelial cells. Human breast epithelial cells, MCF10A, were exposed to low-power red (660 nm) and infrared (808 nm) lasers at 0.9 and 1.9 J (32 and 68 J cm
−2
, respectively) at 100 mW (3.6 W cm
−2
). Subsequently, WST-1 proliferation and clonogenic assays were performed. Additionally, the detection of reactive oxygen species (ROS) levels was achieved using the DCFH2-DA probe by flow cytometry analysis. Our results showed no significant changes in cell viability and proliferation after irradiation compared to their control counterparts. Regarding ROS production, we observed a statistically significant decrease when MCF10A cells were exposed to infrared laser at 1.9 J. Therefore, we demonstrated that the PBM neither induces cellular proliferation nor cell death in mammary epithelial cells. In perspective, our findings could support the safety of laser-based PBM on human breasts.

We investigate the generation of quantum steering and nonlocality in a two-qubit system mediated by a one-dimensional plasmonic waveguide, with the qubits initially prepared in the ground state. Our results show that forward-asymmetric driving fields are particularly effective in generating quantum steering, producing higher peak values and an extended temporal duration compared to symmetric or reverse-driving cases. In addition, we find that quantum nonlocality can be generated under configurations where one forward-driving and one reverse-driving field are applied with unequal strengths. We determine the distinct optimal coupling strengths for maximizing transient steerability and steady-state steerability respectively, which may be beneficial for experimental implementation. Interestingly, a comparison between different initial qubit states (the ground state and maximally entangled state) shows that initial entanglement is not necessary for achieving steady-state steering, as both states produce nearly identical outcomes.

The survey discusses the problem of measuring correlations in composite quantum and statistical systems. After briefly recalling the standard methods of describing correlations, the emphasis is on the method of correlation indices. The latter method for quantifying the strength of correlations in composite physical systems is sufficiently general allowing for measuring in a unique way the correlation strength in both quantum and statistical systems, for static as well as for dynamic processes. The correlation indices, can be defined for correlation operators, reduced density matrices, and other operators containing information on correlations in the studied composite systems. The correlation indices measure all types of correlations, quantum correlations, such as entanglement, as well as classical correlations. They are applicable for characterizing static as well as dynamical processes. Examples are given of correlation indices for several quantum states and for spin and pseudospin systems. The quantification of correlations in a nonequilibrium system is exemplified by calculating the correlation index for a trapped Bose–Einstein condensate subject to the action of an alternating field.

Photodynamic therapy (PDT) has been widely employed in clinical applications, healthcare, and public health (e.g. cancer research, microbiological control, vector control, etc). The photodynamic action is an advanced oxidation process based on the production of reactive oxygen species (ROS) and singlet oxygen by the excitation of a photosensitizer by specific wavelengths of light in the presence of molecular oxygen. The generation of ROS, which are highly reactive, encourages the use of PDT against recalcitrant pollutants and resistant parasites, a novel approach for PDT applications. Here, we explored recent research in PDT in water and wastewater treatment, elucidating operational conditions, main targets, potentials, and constraints, considering a collection of scientific papers curated by a well-defined research strategy. Retrieved records were filtered by subjects, and data was organized into a content network. Results showed that PDT is a timely alternative to deal with emerging chemical contaminants, resistant microorganisms, and other challenges, raising opportunities for versatile applications and sustainable solutions. Advances in environmental applications of PDT may help reach the Sustainable Development Goal 6 (SDG 6), but also positively impact other SDGs.

Energy deposition via laser-induced breakdown (LIB) in gases or other media and its accompanying secondary light and sound radiative processes are nowadays increasingly deployed in scientific and technological applications. The modeling and control of the breakdown and radiative processes occurring by the interactions of the free electrons with the heavy particles in the partially ionized medium, requires precise spatio-temporal description of the generated free electron density. This work presents an analysis of a free electron rate model describing the free electron density in air plasmas produced by nanosecond laser pulses. The model accounts for multiphoton and cascade ionization, and for electron diffusion, recombination, and attachment. A closed-form expression of the rate model is derived and validated by comparison with experimentally validated numerical solutions, showing very good agreement in a wide range of parameters. Simulation results are presented for different laser pulses and focal spot sizes and analysis is carried out regarding the dependence of the air plasma on the various laser radiation parameters. The presented approach is particularly useful for complex multi-scale models calculating the electron and ion temperature evolution, the thermoelastic expansion and the shock-wave following LIB of gases.

Pulsed laser ablation in liquid (PLAL) is an important method for synthesizing metal nanoparticles (NPs). Recently, it has garnered increasing interest as it is simple, rapid, and ecofriendly. Herein, PLAL is proposed as an approach to produce varied sizes of silver nanoparticles (Ag NPs) because NP size plays a vital role in their characteristics and several applications in the physical, chemical, biological, and medical fields. In PLAL, metal NP size could be controlled by either adjusting the laser parameters, such as wavelength, energy, fluence, reptation rate, ablation time, and focusing lens, or by modifying the ablation solvent properties. Herein, PLAL is proved as an effective and simple method for fabricating Ag NPs. This can provide guidance for synthesizing nanomaterials in diverse sizes, types, and shapes for applications in different fields.

Amyotrophic lateral sclerosis (ALS) is a severe neurodegenerative disorder with few existing therapies. Fused-in-sarcoma (FUS) gene mutations underlie many cases of ALS worldwide, whereas 70 kDa heat shock protein (HSP70) was shown to be beneficial for neuronal resistance in ALS. In this study, we observed structural changes in the nervous tissue of the spinal cord when FUS and a member of the HSP70 family, HSPA1A, were expressed together. We regarded fluorescent markers of neurons and neuroglial cells in mice with a transgenic FUS model of ALS, comparing them to transgenic animals with HSPA1A overexpression in cells, Hsp70 (in), and in extracellular substance, Hsp70 (out), and to double transgenic mice with both HSPA1A and FUS genes. We revealed the count of neuronal marker NeuN to be significantly decreased in transgenic FUS animals compared to the intact mice from the control group, whereas it increased in double transgenic FUS + Hsp70 (in) animals. The counts of GFAP, astroglial marker, and Iba1, microglial marker, were increased in transgenic FUS mice with a slight but significant decrease in FUS + Hsp70 (in) mice. Overall survival of transgenic FUS animals was less than that of FUS + Hsp70 (in) mice but even higher than the survival of FUS + Hsp70 (out) mice. We consider that HSPA1A in cells of animals with aberrant FUS has a strong impact on their longevity, neuronal survival, and neuroinflammation avoidance. The data from our study outline intracellular HSPA1A as an important target for the development of disease-modifying therapies for FUS-related ALS.

We investigate the band structure in a nonreciprocal Su–Schrieffer–Heeger (SSH) lattice that incorporates both nearest-neighbor and next-nearest-neighbor (NNN) couplings. Our analysis demonstrates that NNN coupling gives rise to distinctive dangling modes, which emerge when the intracell coupling strength predominates over the intercell coupling. Consequently, the energy levels of edge modes in the topologically nontrivial regime exhibit a dependence on structural parameters. Notably, increasing the nonreciprocal strength lifts the degeneracy of these dangling modes, while enhancing the long-range coupling restores their degeneracy. These findings indicate that the interplay between long-range and nonreciprocal couplings provides a powerful means to control the spatial localization of edge modes and the characteristics of the non-Hermitian skin effect. Experimentally, we achieve nonreciprocal NNN coupling in a zigzag array of optical microring resonators by adiabatically eliminating a dissipative auxiliary mode in a three-mode system, enabling tunable asymmetric coupling through phase modulation. Our results underscore the crucial role of long-range coupling in reshaping band structure and topological features of nonreciprocal SSH systems.

We have effectively developed a formaldehyde concentration sensor based on an optical fiber displacement sensor. Two distinct approaches based on displacement tuning and reflection spectrum measurement in combination with a UV light source were used to test our sensor. The UV–visible light source (OSL 2 Thorlabs) was used to illuminate the sample, and the power output of the backscattered radiation dropped linearly with the formaldehyde concentration. The sensor we tested showed remarkable sensitivity, linearity, and stability in measuring formaldehyde concentrations between 0% and 5%. The displacement tuning scheme achieved a sensitivity of 0.031
W/% with a linearity of 91%, whereas the reflection method exhibited a sensitivity of 2634.3 counts/% and a linearity of 98%. Furthermore, our sensor is non-contact, shielding the sample and probe from danger and damage. These findings show that our fiber bundle sensor has the potential to be a suitable instrument for tracking formaldehyde concentrations in the future for applications related to food safety.

The stimulated emission (SE) signal in pump-probe experiment is conventionally measured with lock-in detection to differentiate the weak signals from the relatively large background of spontaneous emission and probe beam. Therefore, direct characterization of signal strength are often major limiting factors in terms of noise, speed, and data acquisition. In contrast, photon counting allows direct quantification of signal strength, while synchronized pump-probe pulse enables precise timing and the separation of signals accordingly. Herein, the SE based pump-probe method is combined with time-correlated single-photon counting to investigate the ultrafast photochemical parameters, digitally and quantitatively. As a proof-of-concept, our technique is applied to investigate, fluorescence lifetime
, optical absorption cross-section
, and the SE cross-section
, of a fluorescent dye (ATTO 647N) quantitatively. The experimental results are also compared with theoretical photon statistics to further justify the advantages including experimental and statistical critical molecular dynamics parameters extraction with excellent high accuracy.

When two electrons are emitted from a metal needle tip with the help of femtosecond laser pulses, they show a strong anticorrelation signal in the energy domain. Depending on the wavelength and intensity of the driving laser pulses, the electron emission process can be either in a perturbative regime, like single- or multi-photon photoemission, or in the strong-field regime, where emission is dominated by the instantaneous electric field of the laser pulse, or in the intermediate regime. Here, we report on the two-electron anticorrelation signal and how it evolves from the multiphoton toward the strong-field emission regime. We show that in both cases, the resulting anticorrelation signal can be well explained by semi-classical simulations using a point-particle model, thus the dynamics is dominated by the center-of-mass dynamics of the individual electrons. However, the actual emission process of multiple interacting electrons requires improved quantum mechanical models and therefore remains the subject of future work.

In the past, laser propagation in a fluid with heat transfer has been modeled using simplistic conduction and convection conditions yielding inaccurate predictions. Here we present a detailed numerical study describing the thermal profile of the fluid and its interaction with the laser. Furthermore, we evaluate the diffraction field in the far field produced by a pump beam impinging in the fluid and the interferometric pattern obtained normal to the propagation direction to test our model. Direct comparison between experimental results and numerical simulation allows for a complete understanding of the energy transfer from the laser to the liquid and the subsequent effect on the laser propagation. Spatial self-phase modulation and propagation control from small-phase diffraction to aberration-controlled diffraction and up to diffraction oscillation are observed and explained with our modeling.

High pulse energy, low-alignment sensitivity master-oscillator power-amplifier (MOPA) systems enable portable long range laser devices. Comprehensive amplifier modelling is an essential tool in producing efficient, optimised amplfication capable of producing high pulse energies. This paper outlines the development of a large-mode, low-alignment sensitivity neodymium yttrium aluminium garnet (Nd:YAG) (MOPA) system, achieving a total output pulse energy of 265 mJ with an optical efficiency of 18%. A Q-switched diode-pumped Nd:YAG zig-zag oscillator is developed with an output pulse energy of 98 mJ and slope efficiency of 31%. Through the use of an intracavity aperture, the beam quality exhibited an M
of 4.3 and 4.6 and far field divergence of 1.3 mrad and 1.2 mrad in the horizontal and vertical, respectively. The oscillator output is amplified within a diode-pumped Nd:YAG zig-zag amplifier with a system amplification of 2.8. Comprehensive amplifier modelling based on a Frantz-Nodvik analysis is demonstrated, with the saturation characteristics suggesting a route to further energy enhancement and highlighting the necessity for amplifier modelling in high energy system design.

, Novel semi-quantum private comparison protocol with Bell states
Based on Bell states, a new semi-quantum private comparison protocol is proposed that enables two classical users to securely compare the equality of their private information with the aid of a semi-honest third party. Different from the existing semi-quantum private comparison protocols, the two classical participants in the presented protocol do not need to measure and prepare any quantum state, which not only reduces the consumption of quantum devices, but also greatly improves the feasibility of the protocol. Performing different unitary operations on the received particles, classical users can securely compare their secret information. Besides, the devised protocol has higher qubit efficiency than the other similar counterparts, since participants can compare a two-bit privacy each time with one qubit. Meanwhile, after completing the comparison process, all Bell states could be reused since they still retain the corresponding entanglement property, which greatly facilitates the recycle of quantum resources. Security analyses indicate that the designed scheme is secure against external attack and internal attack. Moreover, the operations involved in our scheme are simulated on the IBM Quantum Experience to demonstrate the effectiveness and security of our scheme.

A novel measurement-free mediated semi-quantum key distribution (MSQKD) protocol is proposed based on single-particle states. It enables two classical users to establish a secret key with the assistance of a third party. This protocol simplifies the third party’s role to solely generating qubits in X-basis and conducting Bell measurements. A distinctive feature of this protocol is the efficient grouping and reordering of qubits by the classical users with a minimum of three delay lines. Security analyses demonstrate that the protocol can withstand various attack strategies, including collective attack, measurement attack, fake state attack, and modification attack. The noise tolerance is given by deriving a lower bound of the protocol’s key rate in the asymptotic scenario. Simulations on the IBM Quantum Experience platform are conducted to illustrate the feasibility of this protocol. Compared with existing MSQKD protocols, the proposed protocol consumes fewer quantum resources and achieves a qubit efficiency of 1/8.

Semi-quantum private comparison is a method for private comparison with fewer quantum resources, enabling classical participants to collaborate with a semi-honest third party possessing complete quantum capabilities. A one-way quantum private comparison protocol is devised only by unitary operations. The protocol facilitates one-way transmission between third party (TP) and classical participants in quantum communication, where the classical participants only need to perform unitary operations and measurement operations on the transmitted qubits. In addition, classical participants do not require pre-shared keys. It is shown that the qubit efficiency of this protocol is 12.5%. Finally, security analysis and the simulation results on the IBM Quantum Experience demonstrate the security and the feasibility of this protocol.

, Vector method for strain estimation in phase-sensitive optical coherence elastography
A noise-tolerant approach to strain estimation in phase-sensitive optical coherence elastography, robust to decorrelation distortions, is discussed. The method is based on evaluation of interframe phase-variation gradient, but its main feature is that the phase is singled out at the very last step of the gradient estimation. All intermediate steps operate with complex-valued optical coherence tomography (OCT) signals represented as vectors in the complex plane (hence, we call this approach the ‘vector’ method). In comparison with such a popular method as least-square fitting of the phase-difference slope over a selected region (even in the improved variant with amplitude weighting for suppressing small-amplitude noisy pixels), the vector approach demonstrates superior tolerance to both additive noise in the receiving system and speckle-decorrelation caused by tissue straining. Another advantage of the vector approach is that it obviates the usual necessity of error-prone phase unwrapping. Here, special attention is paid to modifications of the vector method that make it especially suitable for processing deformations with significant lateral inhomogeneity, which often occur in real situations. The method’s advantages are demonstrated using both simulated and real OCT scans obtained during reshaping of a collagenous tissue sample irradiated by an IR laser beam producing complex spatially inhomogeneous deformations.

We investigate how the classical correlations between successive actions of a colored dephasing channel affect the decoherence of a two-qubit system. Our calculation shows that the
norm of coherence, the relative entropy of coherence, and the robustness of coherence can be noticeably enhanced by increasing the strength
of classical correlations in the whole time interval during which the two qubits pass through the channel, while the coherence weight is enhanced only when
exceeds a critical value. Moreover, in the infinite-time limit, all the coherence measures reach their steady values which are determined only by

Surface plasmon resonance (SPR) has become an important optical biosensing technology due to its real-time, label-free, and noninvasive nature. These techniques allow for rapid and ultra-sensitive detection of biological analytes, with applications in medical diagnostics, environmental monitoring, and agriculture. SPR is widely used in the detection of biomolecular interactions, and improvements are required for both sensitivity and
in vivo
uses for practical applications.
In this study, we developed an SPR biosensor to provide a highly sensitive and specific approach to early-stage detection of viral and malignant diseases, such as cancer tumors, for which biomarker detection is very important. A cancer cell line (HeLa cells) with biomarker Rodamine 6G was experimentally analyzed
in vitro
with our constructed SPR biosensor. It was observed that the biosensor can offer a potentially powerful solution for tumor screening with dominant angular shift. The angular shift for both regents is dominant with a time curve at a wavelength of 632.8 nm of a He–Ne laser. We have successfully captured and detected a biomarker
in vitro
for cancer diagnostics using the developed instrument.

The graphical results promise that the absorption coefficient is strongly dependent on Hermite mode index

associated with the cosh term, laser beam width, laser beam frequency, electron Bernstein wave frequency, electron cyclotron frequency, electron thermal velocity and collisional frequency. Nonlinear coupling, collision phenomena and laser beam decentered parameter (very sensitive parameter) play an important role in absorption processes. The association of a very small electron Bernstein wave frequency with the laser beam causes too much of an increase in the absorption coefficient compared to only the laser beam. This efficient nonlinear absorption process may be applicable to plasma electron heating and the harmonic generation process.

A multifunctional photonic broadband RF memory structure is presented to adapt to more and more complex electronic jamming scenarios. Based on precise sequence control of the structure with integration of switching and amplification functions at the output end, the response time of the structure is greatly reduced to 30 ns. Moreover, multiple jamming modes including reconfiguration of Doppler frequency shift (DFS), instantaneous bandwidth (IBW), center frequency, pulse width, storage time and pulse number are realized based on a coherent DFS structure with tunable optical filter and a memory structure with Vernier effect. The tuning range of DFS is greater than ±9 MHz, the reconfiguration range of IBW is 1.5 GHz–11 GHz, the tuning range of center frequency is 6.5 GHz–17 GHz, the maximum storage time of 100 ns–10
s RF pulse signals is 750
