openfermion.circuits.optimal_givens_decomposition

Implement a circuit that provides the unitary that is generated by single-particle fermion generators

Main aliases

openfermion.circuits.optimal_givens_decomposition(
    qubits: Sequence[cirq.Qid], unitary: numpy.ndarray
) -> Iterable[cirq.Operation]

\[ U(v) = exp(log(v)_{p,q}(a_{p}^{\dagger}a_{q} - a_{q}^{\dagger}a_{p}) \]

This can be used for implementing an exact single-body basis rotation

Args
`qubits`	Sequence of qubits to apply the operations over. The qubits should be ordered in linear physical order. unitary:
