【摘要】：量子系统自测试研究如何利用量子系统本身来测试其可信性,即根据量子设备的经典输入输出之间的统计关系来确认设备中所制备的量子态和所执行的量子测量.在经典世界中,要实现这种"设备自己测试自己"的目标并不可行,但量子力学中的非局域性却使这种自测试成为可能.量子系统自测试是设备无关量子密码协议的理论基础.综述了量子系统自测试领域的研究进展.具体来说,首先详细介绍了由两粒子最大纠缠态(即单态)及相应量子测量所构成的两方量子系统的自测试,包括测试1对量子态的CHSH方案、Mayers-Yao方案、(2,2,2,2)通用方案、(N,N,2,2)链式Bell方案,和测试2对量子态的双CHSH方案、魔方方案等.在此基础上,简要介绍了两方部分纠缠态及多方量子系统的自测试方案.最后对量子系统自测试未来的发展进行了展望.
[Abstract]:The self-test of quantum system studies how to use the quantum system itself to test its credibility, that is, to confirm the quantum states prepared in the device and the quantum measurement performed according to the statistical relationship between the classical input and output of the quantum equipment.In the classical world, it is not feasible to achieve the goal of "equipment testing itself", but the nonlocality of quantum mechanics makes the self-testing possible.Quantum system self-testing is the theoretical basis of device-independent quantum cryptography protocol.The research progress in the field of quantum system self-testing is reviewed in this paper.Specifically, the self-testing of two-party quantum systems consisting of the two-particle maximal entangled state (single state) and the corresponding quantum measurements is introduced in detail, including the CHSH scheme for testing one pair of quantum states and the Mayers-Yao scheme / CHSH scheme / 2 / 2 / 2 / 2) Bell scheme.And test 2 pairs of quantum state double CHSH scheme, Rubik's cube scheme and so on.On this basis, the self-testing scheme of two-party partially entangled states and multi-party quantum systems is briefly introduced.Finally, the future development of quantum system self-testing is prospected.
