对非定域性的量子界限(齐尔森界限)的物理解释是量子理论中的一个基本问题,因为众所周知,单靠无信号不能再现这种极限。在这里,信息不可区分性被表示为量子比特或更一般比特的不可区分性,它提出了非定域性难题的答案,最终将其视为量子极限的起源。不可约性也与排他性原理有关,并且证明了不可约性导致量子关联界。这意味着不可分割性与非定域实在论的非定域性和相对论因果性一样重要。
A physical explanation for quantum bounds to nonlocality (Tsirelson’s bound) is a fundamental problem in quantum theory, for it is known that no-signaling alone fails to reproduce this limit. Here, information indistinguishability is presented as the indistinguishability of qubits or more general bits, and it suggests an answer to the nonlocality conundrum, ultimately placing it as the origin to quantum limits. Indistinguishability is also connected to exclusivity principle, and it is shown that indistinguishability leads to quantum correlation bounds. This suggests indistinguishability be as fundamental as non-locality and relativistic causality for nonlocal realism.
