| 英文摘要 |
| A routing protocol is proposed for the fiber quantum communication network. Quantum communication
network can be constructed based on the existing optical fiber communication network through using the repeater with
entanglement swapping and entanglement purification. And based on the repeater, a practical quantum communication can
be constructed with the use of nesting purification protocol. To the innate features of quantum communication network, a
system of evaluation metrics on routing protocol of quantum communication network is presented and analyzed detailed.
The consumption of the entanglement resources and the routing time for the best resulting fidelity within the building
of quantum channel are key considered in the routing protocol, and the quantum communication channel can be chosen
preferred from the process of these indicators analysis. The proposed routing protocol based on analytical calculation and
optimization design is connected with the practical quantum communication system closely, and the simulation results show
that the routing protocol can be operated well. |
