openfermion.linalg.expectation_computational_basis_state

Compute expectation value of operator with a state.

Main aliases

openfermion.linalg.expectation_computational_basis_state(
    operator, computational_basis_state
)

Args
`operator`	Qubit or FermionOperator to evaluate expectation value of. If operator is a FermionOperator, it must be normal-ordered. computational_basis_state (scipy.sparse vector / list): normalized computational basis state (if scipy.sparse vector), or list of occupied orbitals.

Returns
A real float giving expectation value.

Raises
`TypeError`	Incorrect operator or state type.
