(a) Measured truth table. (b) Experimental tomographic reconstruction of the Bell state |Φ+〉 obtained by injecting the separable state |+0〉 in the CNOT. (c) Measured probabilities of the output Bell states corresponding to the different input separable states. (d) Measured probabilities of the output separable states corresponding to the different input Bell states.
