new_uhrig_sequence
- qctrlopencontrols.new_uhrig_sequence(duration, offset_count, pre_post_rotation=False, name=None)[source]
Creates the Uhrig 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 Uhrig sequence.
- Return type
Notes
The Uhrig sequence 1 is parameterized by duration \(\tau\) and number of offsets \(n\). The sequence consists of \(Y_{\pi}\) operations at offsets given by
\[t_i = \tau \sin^2 \left( \frac{i\pi}{2(n+1)} \right) \;,\]where \(i = 1, \cdots, n\).
