英文摘要： In recent years, research on quantum computing based on superconducting qubits has attracted much attention. We will carry out extensive researches on several problems related to quantum computing in the system of the superconducting qubits.The main contents include that the preparation of the quantum logic gate and entanglement state by using of the interaction between superconducting qubits and transmission line resonator. Besides, the methods to solve the problems related to fast decoherence in superconducting qubits with different interaction mechanisms will also be studied.By carrying out this project,the physical nature and characteristics of the superconducting qubits will be fully revealed. At the same time, this project will provide the reliable physical models and theoretical bases to practical quantum computing in solid state systems.
