我们提出并分析了一个拓扑量子比特和超导磁通量子比特之间的接口。在我们的方案中，拓扑绝缘体中Majorana费米子之间的相互作用由超导相位相干控制，超导相位取决于通量量子比特的量子态。控制相位门，通过脉冲打开和关闭这种相互作用来实现，可以在拓扑量子比特和超导量子比特之间传输量子信息。
We propose and analyze an interface between a topological qubit and a superconducting flux qubit. In our scheme, the interaction between Majorana fermions in a topological insulator is coherently controlled by a superconducting phase that depends on the quantum state of the flux qubit. A controlled-phase gate, achieved by pulsing this interaction on and off, can transfer quantum information between the topological qubit and the superconducting qubit.
