我们提出了一种方案,物理实现一种拓扑消相干保护量子比特使用超导器件耦合到微波腔模式与非常规的几何操作。它表明,两个所需的相互作用的选择性设备,这是需要实施这样的保护量子位,以及单量子位门,可以通过使用外部磁通量来实现。与在捕获离子系统中实施拓扑保护量子位相比,系统中提出的单个寻址与多设备设置的简单组合呈现出明显的优点。
We propose a scenario to physically implement a kind of topologically decoherence-protected qubit using superconducting devices coupled to a microwave cavity mode with unconventional geometric operations. It is shown that the two needed interactions for selective devices, which are required for implementing such protected qubits, as well as single-qubit gates, can be achieved by using the external magnetic flux. The easy combination of individual addressing with the many-device setup proposed in the system presents a distinct merit in comparison with the implementation of topologically protected qubits in a trapped-ion system.
