scqubits.core.operators.iadag_minus_ia(dimension, prefactor=None)[source]#

Operator matrix for prefactor(ia-ia^dag) of size dimension x dimension as ndarray

Parameters:

  • dimension (int) – matrix size

  • prefactor (Union[float, complex, None]) – prefactor multiplying the number operator matrix (if not given, this defaults to 1)

Return type:

ndarray

Returns:

prefactor (ia - ia^dag) as ndarray, size dimension x dimension
