qctrlopencontrols.new_bb1_control(rabi_rotation, maximum_rabi_rate, azimuthal_angle=0.0, name=None)

Creates a BB1 (Wimperis) driven control.

BB1 driven controls are robust to low-frequency noise sources that perturb the amplitude of the control field.

rabi_rotation (float) – The total Rabi rotation $\theta$ to be performed by the driven control.
maximum_rabi_rate (float) – The maximum Rabi frequency $\Omega_{\mathrm max}$ for the driven control.
azimuthal_angle (float , optional) – The azimuthal angle $\phi$ for the rotation. Defaults to 0.
name (str , optional) – An optional string to name the control. Defaults to None.

The driven control $\{(\delta t_n, \Omega_n, \phi_n, \Delta_n)\}$ .

Notes

A BB1 driven control ¹ consists of four control segments:

where

\phi_* = \cos^{-1} \left( -\frac{\theta}{4\pi} \right).
