    "abstract": "We present a quantum circuit that implements a non-demolition measurement of\ncomplementary single- and bi-partite properties of a two-qubit system:\nentanglement and single-partite visibility and predictability. The system must\nbe in a pure state with real coefficients in the computational basis, which\nallows a direct operational interpretation of those properties. The circuit can\nbe realized in many systems of interest to quantum information.",
