Abstract

Experiments involving delayed-choice entanglement swapping seem to suggest that particles can become entangled after they've already been detected. This astonishing result is taken by some to undermine realism about entanglement. In this paper, I argue that one can offer a fully realist explanation of delayed-choice entanglement swapping by countenancing timelike entanglement relations. I argue that such an explanation—radical though it may be—isn't incoherent and doesn't invite paradox. I compare this approach to the antirealist alternative and a more deflationary realist strategy defended by Egg (2013), each of which face certain challenges. The upshot is that we should take seriously the possibility of timelike entanglement and seek to develop a framework for quantum theory which allows for it.

延迟选择纠缠交换的类时间纠缠

涉及延迟选择纠缠交换的实验似乎表明，粒子在已经被探测到之后可能会纠缠在一起。这一惊人的结果被一些人认为是在破坏量子纠缠的现实性。在本文中，我认为人们可以通过支持时间型纠缠关系来提供延迟选择纠缠交换的完全现实主义解释。我认为，这样的解释——尽管可能很激进——并非不连贯，也不会引发悖论。我将这种方法与反现实主义的替代方案以及Egg(2013)捍卫的更具通缩性的现实主义策略进行了比较，两者都面临着一定的挑战。结果是，我们应该认真对待类时间纠缠的可能性，并寻求建立一个允许它存在的量子理论框架。

期刊介绍： Studies in History and Philosophy of Modern Physics is devoted to all aspects of the history and philosophy of modern physics broadly understood, including physical aspects of astronomy, chemistry and other non-biological sciences. The primary focus is on physics from the mid/late-nineteenth century to the present, the period of emergence of the kind of theoretical physics that has come to dominate the exact sciences in the twentieth century. The journal is internationally oriented with contributions from a wide range of perspectives. In addition to purely historical or philosophical papers, the editors particularly encourage papers that combine these two disciplines. The editors are also keen to publish papers of interest to physicists, as well as specialists in history and philosophy of physics.
