摘 要:
用量子空腔耦合的超导电荷比特器件被认为是实现量子信息处理的相当有希望的体系之一.如何在这种可集成的量子体系中实现高保真度的操作是量子信息处理领域的重要课题.文章介绍作者最近提出的在量子腔耦合的超导量子比特中用具有内禀容错功能的几何操作来实现普适量子逻辑门,产生多比特量子纠缠及实现量子纠错编码的一个可行方案.[著者文摘]

Abstract:
Devices based on superconducting-qubits coupled through a microwave cavity show certain promise for quantum information processing. The development of an experimentally feasible approach to achieve high fidelity operation in this scalable system is very important. We introduce here a feasible scheme that can implement a universal set of quantum gates and produce multiqubit entanglement as well as construct quantum error-correcting codes based on the same set of fanlt-tolerant geometric quantum operations.[著者文摘]
