量子理论中的时间对称反事实

Time-Symmetrized Counterfactuals in Quantum Theory

L. Vaidman

摘要:

最近,一些作者批评了Aharonov等人(1964)的工作所提出的时间对称化的量子理论。这种批评的核心是一个以各种形式出现的证明,它表明时间对称化的量子理论的反事实解释与标准量子理论不一致。我在这里认为,明显的矛盾是由于逻辑错误。我分析了量子理论中的反事实概念,并介绍了时间对称的反事实。这些反事实并不会导致与量子理论的预言相矛盾。我讨论了时间对称化的反事实的几个令人惊讶的例子的应用程序,并显示时间对称化的量子形式主义的有用性。

英文摘要:

Recently, several authors have criticized the time-symmetrized quantum theory originated by the work of Aharonov et al. (1964). The core of this criticism was a proof, appearing in various forms, which showed that the counterfactual interpretation of time-symmetrized quantum theory cannot be reconciled with standard quantum theory. I argue here that the apparent contradiction is due to a logical error. I analyze the concept of counterfactuals in quantum theory and introduce time-symmetrized counterfactuals. These counterfactuals do not lead to any contradiction with the predictions of quantum theory. I discuss applications of time-symmetrized counterfactuals to several surprising examples and show the usefulness of the time-symmetrized quantum formalism.
