摘要

本文研究了分布在具有偏振模色散的光纤上的偏振纠缠光子对的退相干性。我们描述了产生纠缠、突然死亡和非局域消失的系统构型，并证明了非局域补偿的可能性。我们的研究结果为基于光纤的量子通信建立了终极边界。

Abrupt disappearance of entangelement in fibers with polarization mode dispersion

We investigate the decoherence of polarization-entangled photon pairs distributed over optical fibers with polarization mode dispersion. We characterize system configurations yielding entanglement sudden death and disappearance of non-locality and show the possibility of non-local compensation. Our results establish the ultimate boundaries for fiber-based quantum communications.
