Abstract

This study proposes a new coding function for the symmetric W state. Based on the new coding function, a theoretical protocol of deterministic quantum communication (DQC) is proposed. The sender can use the proposed coding function to encode his/her message, and the receiver can perform the imperfect Bell measurement to obtain the sender's message. In comparison to the existing DQC protocols that also use the W class state, the proposed protocol is more efficient and also more practical within today's technology. Moreover, the security of this protocol is analyzed to show that any eavesdropper will be detected with a very high probability under both the ideal and the noisy quantum channel.
