openfermion.linalg.jordan_wigner_sparse

Initialize a Scipy sparse matrix from a FermionOperator.

openfermion.linalg.jordan_wigner_sparse(
    fermion_operator, n_qubits=None
)

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

fermion_operator FermionOperator

instance of the FermionOperator class.

n_qubits int

Number of qubits.

The corresponding Scipy sparse matrix.
