量子理论的非定域性

Nonlocal character of quantum theory?

N. David Mermin

摘要:

亨利·斯塔普(Henry Stapp)在最近的一篇以上述标题(但没有问号)为标题的文章中提出了一些论点,这些论点使他得出这样的结论:在适当的条件下,“一个只涉及早期现象的陈述的真实性”必须“取决于实验者在以后自由选择进行哪种测量。“我指出,导致这一结论的推理依赖于一个基本的模糊性,当这样一个陈述包含反事实条件时,表达‘只指局限于较早时间的现象的陈述’的含义。因此,这一论证并不能证明这样的结论是正确的,即可以有一个参考框架,在这个框架中,未来的选择可以影响当前的事实。但它确实提供了一个有启发性的和有趣的不同的机会来说明玻尔对爱因斯坦,波多尔斯基和罗森的回答的中心点。

英文摘要:

In a recent article under the above title (but without the question mark) Henry Stapp presented arguments which lead him to conclude that under suitable conditions ``the truth of a statement that refers only to phenomena confined to an earlier time'' must ``depend on which measurement an experimenter freely chooses to perform at a later time.'' I point out that the reasoning leading to this conclusion relies on an essential ambiguity regarding the meaning of the expression ``statement that refers only to phenomena confined to an earlier time'' when such a statement contains counterfactual conditionals. As a result the argumentation does not justify the conclusion that there can be frames of reference in which future choices can affect present facts. But it does provide an instructive and interestingly different opportunity to illustrate a central point of Bohr's reply to Einstein, Podolsky, and Rosen.
