This paper experimentally demonstrates that by eliminating redundant information-reconciliation leakage in the GLLP framework for decoy-state QKD, practical silicon-photonic chip systems can achieve secure key rate improvements of up to 78.82% and tolerate an additional 2.35 dB of system loss without requiring hardware modifications.
This study combines DFT–NEGF simulations and machine learning to demonstrate that atomic-scale electrode geometry critically governs the structural, electronic, and transport properties of Au–pentane–Au molecular junctions, revealing that while highly coordinated flat electrodes maximize conductance and thermoelectric power, lower-coordination tips enhance the Seebeck coefficient, and an XGBoost model trained on these descriptors achieves high-accuracy prediction of transport behavior.
This paper proposes a spherical laser inertial fusion reactor design that utilizes a transparent fused silica first wall with a water absorber for energy conversion, a segmented spherical laser system for pellet compression, a volumetric fast ignition scheme via colliding ion beams, and a novel laser magnetic confinement system to protect the reactor wall.
This paper proposes a falsifiable, discrete information-theoretic framework modeling physical systems on a space-cell substrate where matter is defined as propagated relational information, demonstrating how local unitary dynamics can yield continuum limits, Dirac-like behavior, and gauge structures without deriving the full Standard Model or General Relativity.
This paper presents an accelerated materials discovery framework combining diffusion-based structure generation with hierarchical machine learning and DFT screening to identify over 300 low-energy rare-earth–transition-metal magnetic alloys, including stable phases with saturation magnetization up to ~1.8 T, while providing systematic insights into dopant selection and structural origins for future high-performance magnet design.
This study investigates the core-valence double ionization of SF6 near the S2p, F1s, and S1s edges through combined experimental spectroscopy and quantum chemical calculations, revealing how core holes substantially rearrange molecular orbital ordering, influence singlet-triplet splittings via exchange interactions, and necessitate specific theoretical models to account for observed spectral features and symmetry breaking.
This study demonstrates that the arrival directions of cosmic-ray muons measured by a muon telescope serve as a high-entropy physical source capable of generating approximately 650 bits per second, offering a potential solution for closing the settings-independence loophole in Bell inequality tests.
This paper numerically investigates the dynamical behaviors of a resonant tunneling diode coupled to a laser diode under sinusoidal current modulation, revealing how spike generation, bursting patterns, and chaotic dynamics emerge and evolve across different regions of the RTD's nonlinear current-voltage characteristics.
This paper derives quantum mechanics and the Dirac equation from ExB-T vortex geometry by demonstrating that the circulation quantization condition possesses a fourfold structure—encompassing circulation, integrality, spinor topology, and Lorentz covariance—which, when locked via a rotating-magnetic-field principle, establishes a strict equivalence between Madelung-type fluid dynamics and relativistic quantum theory.
This paper evaluates the resilience of solar sail propulsion under extreme space weather by demonstrating that IKAROS-class architectures can withstand a Carrington-level event with minimal torque disruption and no bulk plasma penetration, while introducing a "Net Operational Time" framework that reveals mission lifetimes are ultimately limited by optical and mechanical payload degradation rather than membrane structural failure.
