Dynamics Simulation of Arbitrary Non-Hermitian Systems Based on Quantum Monte Carlo
Xiaogang Li, Kecheng Liu, Qiming Ding
Non-Hermitian quantum systems exhibit unique properties and hold significant promise for diverse applications, yet their dynamical simulation poses a particular challenge due to in…
Quantum Error Mitigation for Sampling Algorithms
Kecheng Liu, Zhenyu Cai
Recent experimental breakthroughs have signalled the imminent arrival of the early fault-tolerant era. However, for a considerable period in the foreseeable future, relying solely…
Robust Mølmer-Sørensen Gate Against Symmetric and Asymmetric Errors
Wenhao Zhang, Gaoxiang Tang, Kecheng Liu +4
To achieve the entangling gate fidelity above the quantum error correction threshold, it is critical to suppress errors due to experimental imperfection. We consider the Mølmer-SÅ
ECDQC: Efficient Compilation for Distributed Quantum Computing with Linear Layout
Kecheng Liu, Yidong Zhou, Haochen Luo +6
In this paper, we propose an efficient compilation method for distributed quantum computing (DQC) using the Linear Nearest Neighbor (LNN) architecture. By exploiting the LNN topolo…
