Theoretical Study on the Nonlocality of Quantum Mechanics based on Mesons

我们研究了与基于包括介子在内的基本粒子的量子力学非局域性的实验相关的几个问题。分析了由于粒子的不可区分性和粒子衰变的被动性质而导致的建立量子关联的问题。我们提出了一套新的测量方法，可以用来描述许多粒子态(如GHz和W)的纠缠。纠缠相对于测量设置的内在相对性质也在我们对关联的处理中变得透明。

We studied several issues associated with experiments designed for testing nonlocality of quantum mechanics based on elementary particles including mesons. The problems for establishing quantum correlations due to the indistinguishablity of particles and their passive nature of decays were analyzed. We proposed a novel set of measures which is useful to characterize the entanglement of many particle states (such as GHZ and W). The intrinsic relative nature of entanglement with respect to measurement setups was also made transparent in our treatment of correlations.
