Cavity-assisted coupling of superconducting qubits for quantum computation

利用超导量子比特实现量子计算在世界范围内备受理论界和实验界的关注.在这一体系中实现量子计算的明显好处是具有非常好的操控技术及容易集成化.过去10年实验的快速突破验证了体系的这些优势.在调节不同比特耦合方面,利用微波腔场耦合比特的平台已经建立起来.该综述将重点介绍如何形成等效的超导电荷比特、它和腔场的耦合,以及利用腔场耦合多个比特等内容.

Quantum computation（QC） with superconducting qubits becomes a subject of intensive experimental and theoretical research around the world.The obvious advantages of this strategy of QC are the efficient control of a quantum circuit and easy integration.The fast experimental progress in the last decade confirms the importance of these advantages.As for tunable coupling between qubits,a new platform was built up with the demonstration of qubits coupled to microwave resonators（cavity）.This review focused on the formation of a superconducting charge qubit,its coupling to a cavity,and cavity-assisted coupling among many qubits.
