Continuous Variable Quantum Secret Sharing with Chinese Remainder Theorem

摘要: Motivated by the structure characteristics of Chinese Remainder Theorem(CRT), a continuous variable quantum secret sharing scheme is proposed to ensure security network-based communication system. The initial decomposed and recovered solving equations CRT which provides various threshold structures enhance universality, flexibility practicability scheme. shares are encoded two-mode squeezed vacuum state displacement operation for distributing. Compared with discrete sharing, this can increase transmission capacity due improved data-processing generation, manipulation, detection. analysis elucidated calculating bit error rates(BERs) under different conditions it demonstrates that has capability protect secrets from eavesdropping dishonest players no matter channel efficiency.
