中文摘要： 随着量子信息学的发展，人们不断地寻找着合适的物理系统用于实现量子计算和量子通讯。大规模量子计算要求物理系统必须具有高度的可扩展性及可操控性。超导量子电路以其高度的可集成性和灵活的可操控性，成为实现量子信息处理的最佳基本单元。然而超导量子位的相干时间非常短，以致于对于实际的量子计算没有足够的量子逻辑操作可以在相干时间内完成。如果将超导量子位与消相干时间长的系综耦合，则可以解决消相干时间短的缺点。因此，本项目主要将基于包含超导量子位的某些混合装置研究量子纠缠的产生、量子态转移、量子逻辑门的形成等量子信息处理问题。

英文摘要： With the development of quantum information, people have been looking for appropriate physical systems used to implement quantum computation and quantum communication. Large-scale quantum computation requires that the physical systems should have scalability and controllability. Therefore the superconducting qubits become hopeful candidates for the basic blocks for quantum information processing due to their well integratability and flexible manipulability. However, the decoherence of the superconducting qubits is relatively fast so that no enough logical operations can be performed during coherence time. Coherence quantum coupling between the superconducting qubits and an ensemble with long coherence time can overcome the disadvantages of superconducting qubits. So this project aims to investigate the quantum information processing problems including the generation of entanglement, the transfer of quantum states, the implementation of quantum logical gates and so on, based on hybrid devices embedding superconducting qubits.
