new_uhrig_sequence

qctrlopencontrols.new_uhrig_sequence(duration, offset_count, pre_post_rotation=False, name=None)

Creates the Uhrig sequence.

Parameters

• duration (float) – Total duration of the sequence $\tau$
• offset_count (int) – Number of offsets $n$
• pre_post_rotation (bool , optional) – If True, a $X_{\pi/2}$False.
• name (string , optional) – Name of the sequence. Defaults to None.

Returns

The Uhrig sequence.

Return type

DynamicDecouplingSequence

Notes

The Uhrig sequence ¹ is parameterized by duration $\tau$ and number of offsets $n$. The sequence consists of $Y_{\pi}$

where $i = 1, \cdots, n$
