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…

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…

Enhancing Fault-Tolerant Surface Code Decoding with Iterative Lattice Reweighting
Yi Tian, Y. Zheng, Xiaoting Wang +1
Efficient and realistic error decoding is crucial for fault-tolerant quantum computation (FTQC) on near-term devices. While decoding is a classical post-processing task, its effect…
