基于波粒二象性的量子光通信系统的研究

A study of modulating quantum optical communication system

结合光子的波粒二象性,提出利用孤子调制承载量子态的方案,着重从调制信道的角度,分别论证了孤子在NLSE光纤和SIT媒介中的传输演变,量子的压缩态和纠缠态可以在孤子的传输演变中产生,从而实现量子的高速调制。这种调制方案,融合了量子和孤子的特性,避免了量子长距离传送所带来的一系列问题,如量子中继等。

The channel can be used for transmmiting quantum states. The paper provides the project of modulating quantum states with soliton on the basis of wave-particle duality. It demonstrates that the quantum entangled states （or squeezed states） can be produced in the soliton transmitting. The project can avoid the series problems caused by quantum long distance transmission, e.g. quantum repeater.
