Abstract
A novel locking operator and a simultaneous dense coding protocol for three receivers based on Bell states are proposed. The locking operator can lock the quantum entanglement channels and the security of the simultaneous dense coding protocol has also been analyzed. Secondly, we calculate the quantum cost of the simultaneous dense coding protocol based on quantum circuit. Furthermore, four success probabilities of the simultaneous dense coding under the six kinds of noise are calculated. We find that success probabilities of the three-party receivers are independent of the encode message. Our proposed simultaneous dense coding protocol may provide some potential applications in quantum communication.
