摘　　要：超导量子系统被认为是最可能用于实现大规模量子计算、量子信息、以及量子存储等的物理系统之一.本文在一种特别设计的超导电荷比特的基础上,通过微波腔与超导比特的相互作用,探讨了在此系统中实现几何相单门以及非常规几何相两量子门的途径,并讨论了制备多量子比特最大纠缠态的方法.Superconducting quantum system is considered to be one of the most potential physical systems in realizing scalable quantum computation, quantum information, and quantum storage. In this paper we discuss the interaction between superconductivity charge qubits and microwave cavity, based on which we also present how to contruct two noncommutable geometric single-qubit gates and an unconventional geometric two-qubit gate, as well as to realize the GHZ state of N qubits.
