scqubits.TunableTransmon.eigensys

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

Calculates eigenvalues and corresponding eigenvectors using scipy.linalg.eigh. Returns two numpy arrays containing the eigenvalues and eigenvectors, respectively.

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

Return type:

Union[Tuple[ndarray, ndarray], SpectrumData]

Returns:

eigenvalues, eigenvectors as numpy arrays or in form of a SpectrumData object
