根据诲森堡测不准原理,使用量子密码可以使通信双方不需要事先准备相同的密码本即可绝对保密地通信。我们基于单光子偏振态的方案利用四个发光二级管作为光子源进行了传送量子公开密钥的原理性实验,得到的未经纠错的系统误码率为6%。
Abstract：Based on Heisenberg's uncertainty principle, quantum cryptography allows two parties who share no secret information beforehand to communicate in absolute security. We describe an experimental demonstration of quantum public key distribution using a simple single photon polarization method with four light -emitting diodes as photon sources. The error rate before correction is 6%.
