论文摘要
违反无信号的原则可能发生在PT对称的演变中,即源于双方纠缠状态的平等和时间逆转的汉密尔顿人的进化。可以使用非规定的内部产品来避免违规。我们表明,即使在使用物理状态媒介之间使用常规Dirac内部产品的形式主义中,也可以在当地保存无信号原则的局部实例,以对应于与Pt-Ammememitric非对称的非对称的非甲米蒂人汉密尔顿人具有真实特征值的汉密尔顿人,其多党纠缠状态,其多党纠缠的状态仍然违反了Bipartite divers divers the Brict the Princter thr Princip。可以通过使用Greenberger-Horne-Zeilinger州来见证这种现象。有趣的是,广义的w国家不支持这种无标记的当地保存。
Violation of the no-signaling principle may occur in PT-symmetric evolutions, that is, evolutions that stem from Hamiltonians that are symmetric with respect to parity and time-reversal, of bipartite entangled states. The violation can be avoided by using a non-conventional inner product. We show that even within the formalism that utilizes the conventional Dirac inner product between physical state vectors, it is possible to obtain instances of local preservation of the no-signaling principle for evolutions corresponding to PT-symmetric non-hermitian Hamiltonians with real eigenvalues, of multiparty entangled states, whose bipartite versions still violate the principle. The phenomenon can be witnessed already by using the Greenberger-Horne-Zeilinger state. Interestingly, the generalized W states do not support such a local preservation of no-signaling.
