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 θ to be performed by the driven control.
- maximum_rabi_rate (float) – The maximum Rabi frequency Ωmax for the driven control.
- azimuthal_angle (float , optional) – The azimuthal angle ϕ for the rotation. Defaults to 0.
- name (str , optional) – An optional string to name the control. Defaults to
None
.
Returns
The driven control {(δtn,Ωn,ϕn,Δn)}.
Return type
Notes
An SK1 driven control 1 2 consists of three control segments:
δtn | Ωn | ϕn | Δn |
θ/Ωmax | Ωmax | ϕ | 0 |
2π/Ωmax | Ωmax | ϕ−ϕ∗ | 0 |
2π/Ωmax | Ωmax | ϕ+ϕ∗ | 0 |
where
ϕ∗=cos−1(−4πθ).
