提出了一种在微波腔中利用射频超导量子干涉器件(SQUID)量子比特实现完整量子计算的方案。在这个与非阿贝尔完整性相关的方案中,通过绝热调谐耦合到SQUID的经典微波脉冲的拉比频率,可以很容易地构造单量子比特门、双量子比特受控相位门以及受控非门。使用当前技术,这些门的保真度估计可能高于90%。
We propose a different scheme to realize holonomic quantum computation with rf superconducting quantum interference device (SQUID) qubits in a microwave cavity. In this scheme associated with the non-Abelian holonomies, the single-qubit gates and a two-qubit controlled-PHASE gate as well as a controlled-NOT gate can be easily constructed by tuning adiabatically the Rabi frequencies of classical microwave pulses coupled to the SQUIDs. The fidelity of these gates is estimated to be possibly higher than 90% with the current technology.
