量子中继器网络的未来将需要各种纠错码之间的互操作性。一些特定的代码转换，甚至一个通用的方法是已知的，但是，没有在量子网络的背景下对这些技术进行详细的分析。在本文中，我们分析了一个广义的过程，以创建贝尔对编码的两个单独的代码之间的非均匀性经常使用的纠错量子中继器网络设计。我们开始与一个物理贝尔对，然后编码每个量子比特在不同的纠错码，使用纠缠纯化，以增加保真度。我们调查了三个不同的协议，用于制备纯化的编码贝尔对。我们在标准的Pauli误差模型下通过Monte Carlo模拟计算了Steane [[7，1，3]]码、距离为3的表面码和单个物理量子比特之间的错误概率，并估计了这些过程的资源效率。本地门错误率允许我们在任何我们选择的代码之间创建高保真逻辑贝尔对。我们发现，一个postselected模型，其中任何检测到的奇偶校验翻转代码稳定器的结果重新启动的协议，执行最好的。
The future of quantum repeater networking will require interoperability between various error-correcting codes. A few specific code conversions and even a generalized method are known, however, no detailed analysis of these techniques in the context of quantum networking has been performed. In this paper we analyze a generalized procedure to create Bell pairs encoded heterogeneously between two separate codes used often in error-corrected quantum repeater network designs. We begin with a physical Bell pair and then encode each qubit in a different error-correcting code, using entanglement purification to increase the fidelity. We investigate three separate protocols for preparing the purified encoded Bell pair. We calculate the error probability of those schemes between the Steane [[7,1,3]] code, a distance-3 surface code, and single physical qubits by Monte Carlo simulation under a standard Pauli error model and estimate the resource efficiency of the procedures. A local gate error rate ofallows us to create high-fidelity logical Bell pairs between any of our chosen codes. We find that a postselected model, where any detected parity flips in code stabilizers result in a restart of the protocol, performs the best.
