可分态上的局部PT-对称演化与无信号破坏

Local PT-symmetric evolutions on separable states and violation of no-signaling

Asmita Kumari, Ujjwal Sen

摘要:

我们发现,局部PT对称演化可以导致违反无信号原理的可分离,甚至经典相关的二分共享量子态。对于经典关联态,从一组零体积中特别选择的PT对称运算也可以保持该原理。用CPT内积代替传统的内积可以消除违规。

英文摘要:

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.
