@@@@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.
