new_carr_purcell_sequence
- qctrlopencontrols.new_carr_purcell_sequence(duration, offset_count, pre_post_rotation=False, name=None)[source]
Creates the Carr-Purcell sequence.
- Parameters
duration (float) – Total duration of the sequence \(\tau\) (in seconds).
offset_count (int) – Number of offsets \(n\).
pre_post_rotation (bool, optional) – If
True, a \(X_{\pi/2}\) rotation is added at the start and end of the sequence. Defaults toFalse.name (string, optional) – Name of the sequence. Defaults to
None.
- Returns
The Carr-Purcell sequence.
- Return type

Notes
The Carr-Purcell sequence 1 is parameterized by the number of offsets \(n\) and duration \(\tau\). The sequence is made up of a set of \(X_{\pi}\) operations applied at
\[t_i = \frac{\tau}{n} \left(i - \frac{1}{2}\right) \;,\]where \(i = 1, \cdots, n\).
