scqubits.TunableTransmon.tphi_1_over_f_cc#
- TunableTransmon.tphi_1_over_f_cc(A_noise=1e-07, i=0, j=1, esys=None, get_rate=False, **kwargs)#
Calculate the 1/f dephasing time (or rate) due to critical current noise.
- Parameters:
A_noise (
float
) – noise strengthi (int >=0) – state index that along with j defines a qubit
j (int >=0) – state index that along with i defines a qubit
esys (
Optional
[Tuple
[ndarray
,ndarray
]]) – evals, evecs tupleget_rate (
bool
) – get rate or time
- Returns:
time or rate – decoherence time in units of \(2\pi ({\rm system\,\,units})\), or rate in inverse units.
- Return type:
float
