qit.seq.dd¶
- qit.seq.dd(name, t, *, amp=1.0, n=1)¶
Dynamical decoupling and refocusing sequences.
- Parameters
name (str) – name of the sequence, in (‘wait’, ‘hahn’, ‘cpmg’, ‘uhrig’, ‘xy4’)
t (float) – total waiting time
amp (float) – pi pulse amplitude (higher amplitude yields faster pi pulses and better-performing sequences)
n (int) – order (if applicable)
- Returns
decoupling/refocusing sequence
- Return type
All these sequences consist of waiting periods interspersed with hard, fast pi pulses around an axis in the XY plane of the qubit. The target operation for all these sequences is \(X^k\), where \(k\) is the number of pi pulses in the sequence. See e.g. [18].
