Abstract :

A three-party quantum secret sharing protocol using secure direct communication is proposed. The protocol is an improved version of Wang et al.’s in terms of efficiency. The improvement is achieved by introducing a new concept of “encoded classical bits” in the decoding phase. Using the proposed protocol, treble amount of message at a time is transmitted instead of doing J. Wang et al.'s protocol thrice. No qubit carrying the message is sent. Therefore, the protocol is completely secure, if the perfect quantum channel is used.
