A quantum secret sharing scheme without monitoring signal disturbance

Original language description

In order to improve the noise tolerability of quantum secret sharing, we propose a quantum secret sharing scheme based on a round-robin differential-phase-shift quantum key distribution (RRDPS-QKD) protocol, named RRDPS-QSS scheme. In the presented scheme, Alice prepares two L-bit weak coherent pulses (trains), and encodes two random bit sequences on each pulse of the two trains through phase modulation. Bob and Charlie measure received quantum signals and obtain the interference clicks and interference positions within their own measurement environment. With the announcement of their interference positions by Bob and Charlie, Alice can compute the QSS's sifted key, while Bob (Charlie) cannot obtain the sifted key without the help of the others. Finally, Alice, Bob, and Charlie could obtain a secret key via reconciliation and privacy amplification after getting enough sifted keys. The numerical simulation results show that the proposed scheme can produce a secure key without monitoring signal disturbance in quantum channels, and has a higher noise tolerance in comparison with the QSS scheme based on the BB84 protocol. The key generation rate of the proposed RRDPS-QSS scheme decreases with two transmission distances. The longer train length is and lower misalignment the error probability the RRDPS-QSS scheme has, the better the key generation rate performance the QSS scheme has.
