Abstract

We propose a decoherence protected protocol for sending single photon quantum states through depolarizing channels. This protocol is implemented via an approximate quantum adder engineered through spontaneous parametric down converters, and shows higher success probability than distilled quantum teleportation protocols for distances below a threshold depending on the properties of the channel.

摘要

我们提出了一种用于通过去极化信道发送单光子量子态的抗退相干协议。该协议通过自发参量下转换工程实现的近似量子加法器来实现，并且在低于取决于信道特性的阈值的距离处，比蒸馏量子隐形传态协议具有更高的成功概率。
