使用通过腔耦合的约瑟夫森结的量子信息处理
Quantum information processing using Josephson junctions coupled through cavities
摘要：
约瑟夫森结已被证明是一种很有前途的固态系统，用于实现量子计算。重要的两量子比特门通常通过最近的相邻量子比特之间的电容耦合来实现。我们提出了一个有效的哈密顿量来描述通过腔耦合的电荷量子比特。我们发现，非平凡的两个量子比特门可以实现这种耦合。在所提出的方案中，局域电荷量子比特和飞行量子比特相互转换的能力意味着量子网络可以使用这个大的可扩展的固态系统来构建。
英文摘要：
Josephson junctions have been shown to be a promising solid-state system for implementation of quantum computation. The significant two-qubit gates are generally realized by the capacitive coupling between the nearest neighbour qubits. We propose an effective Hamiltonian to describe charge qubits coupled through the cavity. We find that nontrivial two-qubit gates may be achieved by this coupling. The ability to interconvert localized charge qubits and flying qubits in the proposed scheme implies that quantum network can be constructed using this large scalable solid-state system.
