Figure 6
Difference of qubit frequencies and its time derivative. (a,b) Time dependence of \(\Delta \omega ^{\text{FF}}=\omega _1^{\text{FF}}-\omega _2^{\text{FF}}\) for the virtual trajectories. The dashed curve represents the \(\Delta \omega =\omega _1-\omega _2\) used in the reference dynamics. The parameters used are the same as in Fig. 5. (c,d) Time dependence of \(d\Delta \omega ^{\text{FF}}/dt\) and \(d\Delta \omega /dt\). (a,c) are for virtual trajectory A, and (b,d) are for virtual trajectory B.
