Fine tuning of CZ flux pulses. #895

Open aorgazf opened 1 week ago

aorgazf commented 1 week ago

Hi, The results of the chevron fit provide a rough estimate of the flux pulse that implements a CZ gate. With that, one runs cz_virtualz multiple times, varying the amplitude of the flux pulse, until the gate effectively implements a rotation of pi. This process is quite slow. It would be nice to have a routine that automatically sweeps around the duration and amplitude parameters found by the chevron routine and calculates the rotation between the qubits, returning the point closest to pi.

Hi @aorgazf, something along those lines was originally performed in #823. The code has not been tested since the last warm-up.
