- qibocal.protocols.two_qubit_interaction.utils.fit_flux_amplitude(matrix, amps, times)[source]#
Estimate amplitude for CZ gate.
Given the pattern of a chevron plot (see for example Fig. 2 here https://arxiv.org/pdf/1907.04818.pdf). This function estimates the CZ amplitude by finding the amplitude which gives the standard deviation, indicating that there are oscillation along the z axis.
- Parameters:
matrix (np.ndarray) – signal matrix
amps (np.ndarray) – amplitudes swept
times (np.ndarray) – duration swept
- Returns:
estimated amplitude index (int): amplitude index delta (float): omega for estimated amplitude
- Return type:
amplitude (float)

Create the pulse sequence for the calibration of two-qubit gate virtual phases.
This function constructs a pulse sequence for a given two-qubit native gate native (CZ or iSWAP) on the specified qubits. The sequence includes: - A preliminary RX90 pulse on the target_qubit. - An optional X pulse on the control_qubit based on the setup type. - A flux pulse implementing the two-qubit native gate. - A delay of duration dt before the final X90 pulse on the target qubit. - Measurement pulses. It is possible to specify the maximum duration for the flux pulses with the flux_pulse_max_duration parameter.
- The function returns:
The full experiment pulse sequence.
The applied flux pulse.
The final VirtualZPhase pulses to be used for phase sweeping.
