单光子和纠缠光子对到达时间的弱测量

Weak Measurement of the Arrival Times of Single Photons and Pairs of Entangled Photons

S. E. Ahnert, M. C. Payne

摘要:

本文提出了一种弱测量光子到达时间的装置。发现这个到达时间的弱值可以远离期望值,并且原则上也在狭义相对论禁止的区域中。我们简要讨论这些结果的影响,以及他们的和解与因果关系的原则。此外,一对光子在贝尔态的弱到达时间的分析表明,这些弱到达时间相关。

英文摘要:

In this paper we propose a setup for the weak measurement of photon arrival time. It is found that the weak values of this arrival time can lie far away from the expectation value, and in principle also in regions forbidden by special relativity. We discuss in brief the implications of these results as well as their reconciliation with the principle of causality. Furthermore, an analysis of the weak arrival times of a pair of photons in a Bell state shows that these weak arrival times are correlated.
