new_sk1_control

qctrlopencontrols.new_sk1_control(rabi_rotation, maximum_rabi_rate, azimuthal_angle=0.0, name=None)

Creates a first order Solovay-Kitaev (SK1) driven control.

SK1 driven controls are robust to low-frequency noise sources that perturb the amplitude of the control field.

Parameters

• 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.

Returns

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

Return type

DrivenControl

Notes

An SK1 driven control ^{1 2} consists of three control segments:
