量子系统中的经典干涉。II。相对论不变性

Classical interventions in quantum systems. II. Relativistic invariance

Asher Peres

摘要:

如果对一个量子系统进行的几次干预被定域在相互类似空间的区域中,它们将在一个洛伦兹框架中被记录为一个“量子跳跃”序列,而在另一个洛伦兹框架中被记录为不同的跳跃序列。条件被指定,必须遵守的各种运营商参与的计算,使这两个不同的序列导致相同的可观察的结果。这些条件类似于量子场论中的等时对易关系。它们足以阻止超光速信号。(The这些结果的推导并不需要前面文章的大部分内容。这里简要地概述了所需要的内容,因此本文基本上是自成一体的。)

英文摘要:

If several interventions performed on a quantum system are localized in mutually space-like regions, they will be recorded as a sequence of ``quantum jumps'' in one Lorentz frame, and as a different sequence of jumps in another Lorentz frame. Conditions are specified that must be obeyed by the various operators involved in the calculations so that these two different sequences lead to the same observable results. These conditions are similar to the equal-time commutation relations in quantum field theory. They are sufficient to prevent superluminal signaling. (The derivation of these results does not require most of the contents of the preceding article. What is needed is briefly summarized here, so that the present article is essentially self-contained.)
