n-Bit Quantum Secret Sharing Protocol Using Quantum Secure Direct Communication

The proposed quantum secret sharing protocol in this article conveys n bit secret messages from the sender to the n receivers making use of a secure direct communication. In this protocol, all users work together to access their secrets. As a result, the security of the proposed protocol is high. The channel used in this design is an entangled 2n-qubit state. The efficiency of this design has been compared with other designs and it turns out that the efficiency of the proposed protocol is equal to that of the best designs. We demonstrate that this protocol is more efficient than the only n-user confidential subscription plan. Also, all stages of the design in a noisy space have been examined.
