摘　　要：近年来,不断发展的量子计算已成为众人关注的焦点.然而,量子硬件存在稀缺性和噪声等问题,这使得研究量子算法、验证量子芯片等行为都依赖运行在经典计算机上的量子模拟器.本文讨论了不同量子模拟器使用的主要模拟方法,并讨论了主流的全振幅状态向量模拟器和基于张量网络的量子模拟器的各种优化.最后,我们总结了量子模拟器的现状和未来发展方向.In recent years,the rapidly evolving quantum computing has become the focus of attention.However,quantum hardware suffers from scarcity and noise,which makes the study of quantum algorithms and the verification of quantum chips rely on quantum simulators running on classical computers.In this study,the main simulation methods used by different quantum simulators are discussed,and various optimizations of mainstream full-amplitude state vector simulators and tensor network-based quantum simulators are explored.Finally,the current status and future directions of quantum simulators are summarized.
