Simultaneous Estimation of Partial-Transpose Moments with Active Memory Independent of the Moment Order
Junxiang Huang, Xiaoyang Wang, Xiao Yuan +1
We study the simultaneous estimation of partial-transpose moments , , of an unknown bipartite -qubit state from indepe…
A unified framework for efficient quantum simulation of nonlinear spectroscopy
Long Xiong, Xiaoyang Wang, Xiaoxia Cai +1
Nonlinear spectroscopy is a cornerstone of quantum science, providing unique access to multi-point correlations, quantum coherence, and couplings that are invisible to linear metho…
Lindbladian Simulation with Commutator Bounds
Xinzhao Wang, Shuo Zhou, Xiaoyang Wang +3
Trotter decomposition provides a simple approach to simulating open quantum systems by decomposing the Lindbladian into a sum of individual terms. While it is established that Trot…
Phase transitions in parametrized quantum circuits
Xiaoyang Wang, Han Xu, Lukas Broers +2
Phase transitions are among the most intriguing phenomena in physical systems, yet their behavior near criticality remain challenging to study using classical algorithms. Parameter…
Learning Quantum Operator Dynamics from Short-Time Data
Jinyang Li, Satoshi Iso, Shunji Matsuura +2
Real-time dynamics of quantum observables provide direct access to excitation spectra and correlation functions in quantum many-body systems, but currently available quantum device…
Quantum Simulations of Opinion Dynamics
Xingyu Guo, Xiaoyang Wang, Lingxiao Wang
Consensus formation is a central problem in collective behavior. In this work, we develop quantum models of opinion dynamics that can be exactly solved and implemented on current q…
