论文摘要
量子网络由由纠缠链接的量子节点组成，可以将量子信息从一个节点传输到另一个节点。操作可以应用于通过经典通信来操纵量子状态的局部节点的量子，并将采用读数/测量来获得结果。在这里，我们使用量子电路来模拟通过其他节点在线性几何形状连接的两个节点之间的量子状态转移。我们探讨了在状态转移的性能方面的门和读数错误之间的相互作用。我们发现，名义成功概率不一定是两个错误率的单调函数，并采用数值模拟和分析工具来了解其相互作用。
Quantum networks consist of quantum nodes that are linked by entanglement and quantum information can be transferred from one node to another. Operations can be applied to qubits of local nodes coordinated by classical communication to manipulate quantum states and readout/measurement will be employed to obtain results. Here, we use quantum circuits to simulate quantum state transfer between two nodes connected in a linear geometry through other nodes. We explore the interplay between gate and readout errors on the performance of state transfer. We find that the nominal success probability is not necessarily a monotonic function of the two error rates and employ numerical simulations and analytic tools to understand their interplay.
