    "abstract": "The information obtained from the operation of a quantum gate on only two\ncomplementary sets of input states is sufficient to estimate the quantum\nprocess fidelity of the gate. In the case of entangling gates, these conditions\ncan be used to predict the multi qubit entanglement capability from the\nfidelities of two non-entangling local operations. It is then possible to\npredict highly non-classical features of the gate such as violations of local\nrealism from the fidelities of two completely classical input-output relations,\nwithout generating any actual entanglement.",
