摘要
提出一个基于超导量子比特系统,利用微波驱动交叉共振技术制备GHZ态的方案。本方案操控比传统方案更简单,量子比特始终处于最佳工作点,不需要额外的磁通来调节跃迁频率,避免了频谱拥挤,延长了相干时间。
In this paper,we present a scheme that based on superconducting qubit system to generate GHZ state through microwave-driven cross resonant technology.Our scheme is more facilitative to manipulate than the conventional schemes,the qubut is always in the optimum spot,no additional flux lines to adjust superconducting qubits＇ transition frequency,and therefore it avoids the obstacle of spectral crowding and extended the coherence time.
