Abstract:

In order to solve the problem of quantum signaling exchange rate for the optimal, a quantum signaling optimal exchange rate algorithm with entanglement swapping was proposed. According to the entanglement exchange scheme with quantum signaling, a quantum signaling fidelity by the composition of mixed quantum states was analyzed. Discussing the impact of quantum signaling exchange rate factors in single-input single-output system (SISO) and multiple-input multiple-output system (MIMO), and an optimal exchange rate was given by calculating. Simulation results shows that the optimal exchange rate is 100qubit/s under the condition that the fidelity is 97% , the index can satisfy the signaling exchange requirements with quantum communication. It is important supporting role in building the future quantum communication system.
