A quantum secret sharing scheme based on two polarization beam splitters

提出一个基于双偏振分束器的单量子比特全光纤量子秘密共享方案,该方案具有自动补偿光纤及光学器件的双折射效应和相位抖动的功能,在干涉对比度测试和稳定性测试时,该方案在5km通信距离中,获得的干涉对比度优于993%,且可长时间保持稳定.

In this paper we present a quantum secret sharing scheme based on a single qubit protocol using two polarization beam splitters.This scheme guarantees an auto compensation of birefringence and phase jitter in single mode fiber and optical device.The visibility is higher than 99.3% over 5 km communication distance with an excellent stability.
