Poisson-Compiled Quantum Singular Value Transformation for Power-Exponential Dissipation
Chao Wang, Xi-Ning Zhuang, Menghan Dou +2
We study quantum implementations of the contraction for and . Poisson summation provides an exact target--alias--tail decomposition whose…
Simulation of Lindbladian dynamics via adaptive variational quantum trajectory compression
Huan-Yu Liu, Cheng Xue, Yun-Jie Wang +5
Quantum simulation of open quantum systems in the noisy intermediate-scale quantum (NISQ) era is hindered by the non-unitary nature of dissipative dynamics and the limited quantum…
Routing Codes: High-Rate Quantum LDPC Codes with Short, Parallel Non-Local Connectivity
Jiaxuan Zhang, Zhao-Yun Chen, Peng Duan +6
Quantum low-density parity-check (qLDPC) codes are promising candidates for realizing large-scale fault-tolerant quantum computing. Although many codes with favorable theoretical p…
Quantum Simulation of Non-Hermitian Special Functions and Dynamics via Contour-based Matrix Decomposition
Chao Wang, Huan-Yu Liu, Cheng Xue +4
Simulating non-Hermitian dynamics on quantum computers is often hindered by the decay of success probability and the instability of non-diagonalizable matrices. Here, we present co…
QuantumQA: Enhancing Scientific Reasoning via Physics-Consistent Dataset and Verification-Aware Reinforcement Learning
Songxin Qu, Tai-Ping Sun, Yun-Jie Wang +8
Large language models (LLMs) show strong capabilities in general reasoning but typically lack reliability in scientific domains like quantum mechanics, which demand strict adherenc…
A Unified Poisson Summation Framework for Generalized Quantum Matrix Transformations
Chao Wang, Xi-Ning Zhuang, Menghan Dou +2
We present a unified algorithmic framework for quantum simulation of non-unitary dynamics and matrix functions, governed by the principle of spectral aliasing derived from the Pois…
