摘　　要：量子非定域性是多体量子系统最基本的特征,可通过量子系统对Bell不等式的违背所揭示。本文基于量子编程语言Q#编写量子程序,统计量子测量结果并计算Bell多项式的量子统计值,进而用经典计算机模拟多体量子系统非定域性。量子模拟结果显示程序运行后得到的统计值与理论计算值基本一致,结果表明基于量子编程的量子模拟在多体量子系统非定域性研究方面具有可行性。Quantum nonlocality is the most basic feature of many-body quantum systems,which can be revealed by the violation of Bell's inequality by the quantum system.Based on quantum programming language Q#,we write quantum programs to calculate the quantum measurement results and the quantum statistics of Bell polynomial and simulate the multi-body quantum system using a classical computer.Quantum simulation results show that the statistical valuesare basically consistent with theoretical results.These results show that the quantum simulation via quantum programming is feasible in the study of non-locality of multi-body quantum systems.
