new_ramsey_sequence

qctrlopencontrols.new_ramsey_sequence(duration, pre_post_rotation=False, name=None)

Creates the Ramsey sequence.

Parameters

• duration (float) – Total duration of the sequence $\tau$ (in seconds).
• pre_post_rotation (bool , optional) – If True, a $X_{\pi / 2}$ rotation is added at the start and end of the sequence. Defaults to False.
• name (string , optional) – Name of the sequence. Defaults to None.

Returns

The Ramsey sequence.

Return type

DynamicDecouplingSequence

Notes

Technically, the Ramsey sequence ¹ does not decouple the system from the environment. Nevertheless, it is a useful sequence for characterization and testing protocols and hence it is included. The sequence is parameterized by the duration $\tau$ and contains no offsets in between the start and the end time of the sequence.
