Comparison between the estimated LZC efficiencies and the measured results. Theoretical estimations with a chirped sweep (orange curve) and HS1 pulse (blue curve). Both the sweeps have the same range of ± 4 kHz around the central frequency and same pulse duration of 4 ms. For the HS1 pulse, Ω_max is set to 3.21 kHz. In chirped modulation, the Rabi frequency is fixed at Ω_max, while the microwave frequency changes with time linearly. The experimental results match very well with the theoretical estimation.
