The complete characterization of the control measurement system. (a) By injecting the state , the two-photon interference is shown via the Hong-Ou-Mandel dip with the obtained visibility of 66.3%. (b) The truth table measured in the computational basis . (c) Demonstration of the ability of the C-NOT gate to transform the maximally entangled states into corresponding product states.
