    dual_basis_action, plane_wave_occ_orbitals, grid, spinless
)

plane wave computational basis state.

Args
dual_basis_action	Dual-basis action of FermionOperator to evaluate expectation value of. plane_wave_occ_orbitals (list): list of occupied plane-wave orbitals. grid (openfermion.utils.Grid): The grid used for discretization. spinless (bool): Whether the system is spinless.

Returns
A float giving the expectation value.
