英文摘要：
In order to build a quantum signaling network with high survivability, quantum channel survival function and survivability of signaling network have been proposed based on the concept of fidelity. The survival coefficient in optical fiber or free space is analyzed, fidelity in noisy quantum channel with the decoherence mechanisms is calculated and survival function test model is proposed. Simulation analysis shows that, by reducing the quantum state transition rate, controlling fiber attenuation coefficient and atmospheric attenuation coefficient, decreasing the time of quantum states evolution, and setting quantum repeaters, we can construct a high survivability of quantum channel and provide a theoretical foundation for the formulation of quantum entanglement signaling network standard.
