论文摘要
当量子通过量子通道传输时，量子网络对干扰很脆弱。可靠性是量子网络甚至未来量子互联网的必不可少的要求。需要一个指标来描述量子网络的可靠性来构建强大的基础架构和通信协议。在这项工作中，我们将量子物理参数与图形代数连接相结合，以指示网格量子网络的传输吞吐量。该指标可以扩展到多个相等的点对点距离拓扑。这项工作还研究了如何调整特定的物理参数，以维持甚至从网络中删除节点或边缘时保持连接性。使用此指标，比较资源消耗。
Quantum network is fragile to disturbances when qubits are transmitted through quantum channel. Reliability is an essential requirement for a quantum network and even the future quantum internet. A metric is needed to describe the reliability of a quantum network to build a robust infrastructure and communication protocols. In this work, we combined quantum physical parameters with graphic algebraic connectivity to indicate the transmission throughput of a grid quantum network. This metric can be extended to multiple equal point-to-point distance topology. This work also studies how to tune specific physical parameters to maintain or even increase connectivity when nodes or edges are removed from a network. Using this metric, resources consumption are compared.
