scqubits.TunableTransmon.eigenvals

TunableTransmon.eigenvals(evals_count=6, filename=None, return_spectrumdata=False)

Calculates eigenvalues using scipy.linalg.eigh, returns numpy array of eigenvalues.

Parameters:

• evals_count (int) – number of desired eigenvalues/eigenstates (default value = 6)

• filename (Optional[str]) – path and filename without suffix, if file output desired (default value = None)

• return_spectrumdata (bool) – if set to true, the returned data is provided as a SpectrumData object (default value = False)

Return type:

Union[SpectrumData, ndarray]

Returns:

eigenvalues as ndarray or in form of a SpectrumData object
