摘　　要：该文研究了二能级射频超导量子干涉仪量子比特与经典微波脉冲的相互作用.研究结果表明,当微波场的角频率接近于系统二能级|0〉|1〉跃迁频率时,即ω1-ω0≈ωm,可以得到一位通用量子逻辑门.通过调节控制微波场的角频率ωm,幅度Vm和脉冲作用时间t,可以得到不同的一位量子逻辑门.The interaction of two-level RF superconducting quantum interference device qubit and classical microwave pulse is investigated. The results show that when the frequency of the microwave is chosen near to the transition frequency for , ie , one-bit general quantum logic gates can be obtained. And that different one - bit logic gates can be obtained by manipulating the interaction , the frequency and the amplitude of the microwave field.
