论文摘要
我们表明，局部PT对称的演变可能导致违反可分离性甚至经典相关的两分共享量子状态的无信号原理。对于经典相关的状态，从一组零体积的特殊选择的PT对称操作也可以保留该原理。可以使用CPT内部产品而不是传统产品来删除违规行为。
We show that local PT-symmetric evolutions can lead to violation of the no-signaling principle for separable and even classically correlated bipartite shared quantum states. For classically correlated states, specially chosen PT-symmetric operations from a set of zero volume can also preserve the principle. The violations can be removed by using a CPT inner product instead of the traditional one.
