摘　　要：随着量子计算机以及量子算法的提出,人们开始寻找可以实现量子计算机的真实物理体系。超导量子电路以其丰富的可设计性和优良的易集成性成为最有潜力实现量子计算机的人造量子体系。文章介绍了超导电荷量子比特的基本原理、超导电荷量子比特的耦合以及耗散和退相干问题,展望了超导电荷量子比特在量子计算和量子信息科学中的应用前景。With the proposal of quantum computer and quantum algorithm, people start looking for the real physical system for quantum computer. Compared to other system, superconducting circuits are more easily embedded in electronic circuits and scaled up to large registers. It becomes the most potential artificial quantum system to achieve quantum computer. This article describes the basic principles and the coupling of superconducting charge qubits. We also introduce the dissipation and decoherence in the superconducting charge qubit and looking forward to the use of it in quantum computing and quantum information.
