scqubits.core.operators.iadag_minus_ia_sparse(dimension, prefactor=None)[source]¶

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

Parameters:

dimension (int) – matrix size
prefactor (Optional[Union`[:py:class:`float, complex]]) – prefactor multiplying the number operator matrix (if not given, this defaults to 1)

Return type:

csc_matrix

Returns:

prefactor * (\(ia-ia^\dagger\)) as sparse operator matrix, size dimension x dimension
