利用非局域量子几何相位检测光信道的非互易性

Detecting Optical Channel Non-Reciprocity with Non-Local Quantum Geometric Phase

James E Troupe, Antia Lamas-Linares

摘要:

非互易器件在量子信息技术中越来越受到关注。本文研究了通信双方是否可以检测到光信道中存在的非互易设备。我们发现,一个非互易设备,如法拉第旋转器的结果在一个可测量的几何相位的光传播通过通道,并且,当使用纠缠光子对,所得到的相位是非本地的和强大的恶意操纵。

英文摘要:

Non-reciprocal devices are of increasing interest in quantum information technologies. This paper examines whether the presence of a non-reciprocal device in an optical channel is detectable by the communicating parties. We find that a non-reciprocal device such as a Faraday Rotator results in a measurable geometric phase for the light propagating through the channel and that, when using entangled photon pairs, the resulting phase is non-local and robust against malicious manipulation.
