A Quantum Information Processing Explanation of Disjunction Effects
... another operator is applied that transforms the initial state into one that has ψDD = ψDC = 0 to produce ψC = [0,0,αC,βC], where βC2 = 1 − αC2. In the unknown case, an operator is applied which produces a superposition state ψU = √½ · ψD + √½ · ψC. The interpretation of this state will be treated in ...
