This paper proposes a universal routing strategy that mitigates the demanding connectivity requirements of quantum LDPC codes by trading off increased syndrome extraction circuit depth for significantly reduced long-range connections, thereby enabling their practical implementation on hardware with limited connectivity.
This paper demonstrates a programmable superconducting quantum simulator capable of independently controlling the anisotropic couplings and bias of the quantum Rabi model, thereby revealing new spectral symmetries, ground-state parity switches, and nonperturbative dynamics that are inaccessible in the isotropic limit.
This paper presents a non-Hermitian quasiperiodic mosaic waveguide array that utilizes exceptional-point encircling dynamics to deterministically select between purely localized and delocalized output states, a mechanism experimentally validated via femtosecond laser direct writing in glass.
This paper introduces a windowed finite-size scaling diagnostic to analyze reference-state information backflow in disordered quantum reservoirs, revealing that finite-reservoir Markovianization is window-dependent and characterized by a disorder-induced transition near that distinguishes boundary-dominated small reservoirs from the scaling behavior of larger extended systems.
This paper presents a hybrid Sb2S3-Si metasurface that leverages polarization-insensitive quasi-bound states in the continuum and a local flat-band to achieve robust, dynamically tunable enhancement of third-harmonic generation across the near-infrared spectrum.
This paper demonstrates that Earth's rotation within its axisymmetric geomagnetic field generates global electric fields that, when interacting with ocean–land conductivity contrasts, create natural "geophysical batteries" with estimated terminal voltages of 10–100 V, particularly concentrated near the Chukchi and Seward peninsulas.
This conceptual proposal suggests that a macroscopic capsule surrounded by a near-light-speed rotating energy shell could theoretically function as a time-dilation domain and a positron source, though the underlying physics relies on unproven assumptions regarding rotating frames and the commercial viability of the concept remains speculative.
This paper presents a rigorous excitonic theoretical framework incorporating Coulomb correlation, dual-interface dielectric self-polarization, local-field corrections, and temperature-dependent dephasing to demonstrate that inverting the core/shell geometry of CdSe/ZnS cylindrical quantum dots significantly enhances third-order nonlinear optical responses, offering optimized design guidelines for oxide-embedded photonic devices.
This study combines advanced experimental spectroscopy and high-accuracy theoretical calculations to reveal that single-photon valence double ionization of ozone produces electronically excited fragments, uncovering a richer dissociation dynamics than previously recognized.
This paper presents a reduced simulation framework linking a 2 kW LLC resonant bias supply to ion energy distribution and surface power spectral density, demonstrating that plasma-load-adaptive gate voltage control offers a robust design route for optimizing the roughness spectrum of ion-beam polished quartz.
