scqubits.TunableTransmon.get_matelements_vs_paramvals#

TunableTransmon.get_matelements_vs_paramvals(operator, param_name, param_vals, evals_count=6, num_cpus=None)#

Calculates matrix elements for a varying system parameter, given an array of parameter values. Returns a SpectrumData object containing matrix element data, eigenvalue data, and eigenstate data..

Parameters:

  • operator (str) – name of class method in string form, returning operator matrix

  • param_name (str) – name of parameter to be varied

  • param_vals (ndarray) – parameter values to be plugged in

  • evals_count (int) – number of desired eigenvalues (sorted from smallest to largest) (default value = 6)

  • num_cpus (Optional[int]) – number of cores to be used for computation (default value: settings.NUM_CPUS)

Return type:

SpectrumData
