Abstract

We combine the eyebrow-raising quantum phenomena of erasure and counterfactuality for the first time, proposing a simple yet unusual quantum eraser: A distant Bob can decide to erase which-path information from Alice's photon, dramatically restoring interference-without previously shared entanglement, and without Alice's photon ever leaving her laboratory.

摘要

我们首次将令人惊讶的擦除和反事实性量子现象结合起来，提出了一种简单却独特的量子擦除器：遥远的鲍勃可以决定擦除爱丽丝光子的路径信息，显著恢复干涉——无需事先共享纠缠，且爱丽丝的光子从未离开过她的实验室。
