    n_qubits, tensor_factor, ladder_type
)

Operators are mapped as follows:

a_j^\dagger -> Z_0 .. Z_{j-1} (X_j - iY_j) / 2
a_j -> Z_0 .. Z_{j-1} (X_j + iY_j) / 2

index This is a nonzero integer. The integer indicates the tensor factor and the sign indicates raising or lowering.
n_qubits int

Number qubits in the system Hilbert space.

The corresponding Scipy sparse matrix.
