Decoherence across phase-space scales: From compass states to general quantum states
Naeem Akhtar, Jia-Xin Peng, Tan Hailin +2
Environmental decoherence occurs when a quantum system interacts with its surroundings, progressively reducing quantum interference and coherence, complicating the preservation of…
Regularized Schrödinger Bridge via Distortion-Perception Perturbation for High-Fidelity Speech Enhancement
Qing Yao, Lijian Gao, Qirong Mao +1
Speech enhancement (SE) requires high-fidelity reconstruction of clean speech that preserves linguistic and paralinguistic cues while maintaining high perceptual quality. Recently,…
Modified logarithmic Sobolev inequalities for CSS codes
Sebastian Stengele, Ángela Capel, Li Gao +5
We consider the class of Davies quantum semigroups modelling thermalization for translation-invariant Calderbank-Shor-Steane (CSS) codes in D dimensions. We prove that conditions o…
Electric spin and valley Hall effects
W. Zeng
The electric Hall effect (EHE) is a newly identified Hall effect characterized by a perpendicular electric field inducing a transverse charge current in two-dimensional (2D) system…
Quantum Mechanics Relative to a Quantum Reference System: a Relative State Approach
M. J. Luo
This paper proposes an intrinsic or background-independent quantum framework based on entangled state rather than absolute quantum state, it describes a quantum relative state betw…
Evanescent-mode-assisted Klein tunneling in dual-gated bilayer graphene
Yupeng Huang, W. Zeng
We theoretically investigate the electron tunneling in dual-gated bilayer graphene-based junctions. It is shown that a band gap is introduced by tuning the gate voltage, whic…
