An algorithm leveraging the Clifford group and graph representation to find symmetries in many-body Hamiltonians, demonstrated on random and physical instances up to 1000 qubits.
Within our notation, two degenerate eigenvalues will be identified with different indices, i.e.,λkl can be the same asλ kl′ for somel,l ′
