new_spin_echo_sequence

qctrlopencontrols.new_spin_echo_sequence(duration, pre_post_rotation=False, name=None)[source]

Creates the spin echo 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 spin echo sequence.

Return type

DynamicDecouplingSequence

Notes

The spin echo sequence 1 is parameterized by duration \(\tau\). There is a single \(X_{\pi}\) unitary operation at \(t_1 = \frac{\tau}{2}\).
