scqubits.core.sweeps.dressed_matrixelement(sweep, paramindex_tuple, paramvals_tuple, operator)[source]#

Given parameter sweep data, compute and return a matrix element table using the dressed states of the composite Hilbert space.

Parameters:

  • sweep (ParameterSweep) – ParameterSweep object to be used for the computation

  • paramindex_tuple (Tuple[int, ...]) – a complete set of parameter indices (i.e. a single point in the multi-dim parameter space)

  • paramvals_tuple (Tuple[float, ...]) – [not used, but required by generator interface]

  • operator (Qobj) – given as Qobj, valid operator in the full Hilbert space

Return type:

ndarray

Returns:

ndarray of matrix elements, in general complex-valued; shape: square array of size set by the truncated_dim of the subsystem
