- scqubits.core.operators.number(dimension, prefactor=None)[source]#
Number operator matrix of size dimension x dimension in sparse matrix representation. An additional prefactor can be directly included in the generation of the matrix by supplying ‘prefactor’.
- Parameters:
dimension (
int
) – matrix dimensionprefactor (
Union
[float
,complex
,None
]) – prefactor multiplying the number operator matrix
- Return type:
ndarray
- Returns:
number operator matrix, size dimension x dimension
