Abstract: Recently, Zhouet al.proposed a quantum secret sharing (QSS) protocol, which provides only 25% qubit efficiency after the processes of the random sampling discussion and the secret derivation. This work proposes an enhancement of Zhouet al.'s protocol. With the technique of the Bell measurement, the improved QSS protocol has 50% qubit efficiency.
