fqe.openfermion_utils.determinant_to_ops

Given the alpha and beta occupation strings return, a fermion operator

fqe.openfermion_utils.determinant_to_ops(
    a_str: int,
    b_str: int,
    inorder: bool = False
) -> "FermionOperator"

which would produce that state when acting on the vacuum.

Args
a_str (bitstring) - spatial orbital occupation by the alpha electrons b_str (bitstring) - spatial orbital occupation by the beta electrons inorder (bool) - flag to control creation and annihilation order

Args

a_str (bitstring) - spatial orbital occupation by the alpha electrons

b_str (bitstring) - spatial orbital occupation by the beta electrons

inorder (bool) - flag to control creation and annihilation order

Returns
(FermionOperator)
