This paper proposes and analyzes a continuous-variable quantum key distribution system for underwater communications that utilizes virtual photon subtraction and quantum multiple-symbol detection to significantly improve robustness against turbulence-induced errors without requiring channel state information.
This paper establishes a measurable quantum advantage for Rabin oblivious transfer using coherent states and unambiguous state discrimination by deriving optimal dishonest receiver bounds that demonstrate the protocol successfully restricts a dishonest receiver's success probability below classical limits while maintaining sender security comparable to classical schemes.
This paper proposes a coupled-resonator-enabled active–passive control strategy that utilizes engineered dispersive waves to simultaneously achieve broad repetition-rate tunability and ultra-low timing noise in Kerr solitons by compensating for the Raman shift and suppressing random-walk motion via cross-phase modulation.
This theoretical study demonstrates that newly predicted Ruddlesden–Popper X₂CeO₄ compounds (X = Mg, Sr, Ba) possess multifunctional properties, including suitable band gaps, high optical conductivity, and enhanced thermal stability, making them promising candidates for next-generation plasmonic, optoelectronic, and thermoelectric applications.
This study utilizes density functional theory and Boltzmann transport theory to demonstrate that stable 2D MoX₂ (X = S, Se, Te) monolayers exhibit tunable semiconducting band gaps, strong visible-ultraviolet optical absorption, and high thermoelectric figures of merit, making them promising candidates for future photoelectronic and energy-conversion applications.
This study presents a physics-informed neural network framework that accurately models the thickness-dependent electron transport and photovoltaic performance of dye-sensitized solar cells using limited experimental data, outperforming traditional regression methods while highlighting the challenges of cross-system generalization due to morphological and electrolyte variations.
Using DFT+DMFT calculations validated by neutron diffraction, this study identifies CaCrO₃ as a rare metallic Hund altermagnet where Hund's coupling, rather than Mottness, drives incoherent metallicity, sustains local spin moments, and induces heavy-fermion-like behavior.
This study demonstrates that composition-driven defect and interface engineering via Zn substitution in Cu₁₋ₓZnₓFe₂O₄ nano-interlayers significantly enhances the structural and electronic properties of Cu/p-Si MIS Schottky photodiodes, resulting in optimized ultraviolet detection performance with high responsivity, quantum efficiency, and detectivity.
This study demonstrates that converting Ti3AlC2 MAX phase to Ti3C2 MXene via selective etching significantly enhances nonlinear optical properties, resulting in superior broadband saturable absorption and passively Q-switched laser performance.
This paper proposes a polarization-insensitive, multi-band graphene-assisted terahertz metasurface biosensor featuring three sharp resonance modes and dynamic electrical tunability, which achieves high sensitivity and quality factors for multiplexed, label-free detection of various biochemical analytes.
