new_spin_echo_sequence

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

Creates the spin echo sequence.

Parameters

  • duration (float) – Total duration of the sequence τ\tau (in seconds).
  • pre_post_rotation (bool , optional) – If True, a Xπ/2X_{\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 τ\tau. There is a single XπX_{\pi} unitary operation at t1=τ2t_1 = \frac{\tau}{2}.
