Joint Mitigation of Algorithmic and Physical Errors in Noisy Hamiltonian Simulation
Shuo Zhou, Xinzhao Wang, Ruiqi Zhang +4
Product-formula Hamiltonian simulation is naturally suited to near-term quantum processors, but its accuracy is set by two competing errors: finite-step Trotter bias and physical h…
Streaming the partial-transpose moment hierarchy with order-independent quantum memory
Junxiang Huang, Xiaoyang Wang, Xiao Yuan +1
Partial transposition reveals mixed-state entanglement through the spectrum of , but this operator is not generally a physical state. Its power moments are accessible…
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…
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…
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…
Exploring Noisy Quantum Thermodynamical Processes via the Depolarizing-Channel Approximation
Jian Li, Xiaoyang Wang, Marcus Huber +2
Noise and errors are unavoidable in any realistic quantum process, including processes designed to reduce noise and errors in the first place. In particular, quantum thermodynamica…
