我们建议实现可调接口，以实现拓扑量子比特的通用量子计算。拓扑量子比特和超导量子比特之间有一个接口，可以在拓扑量子比特上实现任意单量子比特门。当涉及两个量子比特时，拓扑量子比特与微波腔之间的界面会诱导出一个非平凡的双量子比特门，该门无法基于编织操作构建。这两个接口可以通过外部磁通量进行调节，可以作为拓扑量子比特通用量子计算的基石。
We propose to implement tunable interfaces for realizing universal quantum computation with topological qubits. One interface is between the topological and superconducting qubits, which can realize arbitrary single-qubit gate on the topological qubit. When two qubits are involved, the interface between the topological qubits and a microwave cavity can induce a nontrivial two-qubit gate, which can not be constructed based on braiding operations. The two interfaces, being tunable via an external magnetic flux, may serve as the building blocks towards universal quantum computation with topological qubits.
