This paper proposes a robust and high-fidelity scheme for rapidly implementing a controlled π phase gate and generating N-particle cluster states by combining superadiabatic shortcuts with quantum Zeno dynamics in a Rydberg superatom system, demonstrating strong resilience against decoherence and operational imperfections.
This study demonstrates that processing molybdenum and tantalum refractory metal grids in a low-oxygen argon atmosphere significantly reduces surface oxidation and redeposition defects compared to air, whereas tungsten's machining quality is primarily governed by energy density control rather than atmospheric conditions.
This paper introduces budget-conditioned neural error mitigation (NEM), a method that outperforms traditional techniques like zero-noise extrapolation and Clifford data regression in variational quantum algorithms by correcting single-shot measurements across diverse shot budgets, thereby offering superior accuracy and cost-efficiency under realistic device noise and miscalibration.
This paper presents a perturbative analysis of coupled heat and mass transfer in non-isothermal Gordon–Schowalter viscoelastic Couette–Poiseuille flow with Arrhenius kinetics, establishing that the convected-derivative parameter significantly influences thermal and reactive responses through competing advective and thermal-reaction mechanisms governed by a single crossover number that dictates reactor sizing.
This study integrates molecular dynamics simulations with optimized Ogden hyperelastic modeling to characterize the strain-rate-dependent nonlinear compressive behavior of PU-SiC nanocomposites, successfully bridging nanoscale mechanisms with continuum-level constitutive descriptions for advanced engineering applications.
This study utilizes multiscale tomographic diagnostics to demonstrate that a novel gradient porous media architecture effectively suppresses methane/air flame acceleration and pressure oscillations in confined spaces by modulating flow resistance and delaying the transition to turbulence, thereby offering critical design criteria for industrial explosion protection systems.
This study combines high-pressure synchrotron X-ray diffraction with first-principles calculations to reveal that pressure-induced bond order in the frustrated spinel CuIr2S4 arises from an Anderson-type local tetrahedron rule driven by intersite Coulomb interactions, rather than a simple orbitally induced Peierls mechanism.
This paper proposes that a repulsive medium potential significantly enhances the alpha decay rate of quasi-bound states with very small Q-values, offering a potential explanation for anomalous zinc production observed in palladium electrolysis experiments.
This study utilizes biaxial compression tests on sandstone specimens containing a circular opening and a filled fissure to demonstrate that both fissure inclination and filling thickness exert non-monotonic effects on peak strength and deformation, revealing that specific configurations (such as a 15° inclination with 2 mm filling) induce the most severe localized instability and earliest failure, thereby providing critical experimental insights for assessing and supporting roadways adjacent to fault fracture zones.
This equilibrium molecular dynamics study reveals that anisotropic copper nanoparticles (cubic and cylindrical) enhance the thermal conductivity and specific heat capacity of aqueous nanofluids more effectively than spherical ones by reducing interfacial thermal resistance and increasing particle–fluid interactions, albeit at the cost of higher viscosity.
