Contract Type FiledJanuary 23rd, 2018The adversary thus operates as follows. If it finds +x,xr , it concludes that φ was not measured, and if it finds x,xr , it concludes that φ was measured. Since it gets the case without measurement always right, and it basically guesses in the case with measurement, its advantage is 1/2. Hence H is not collapsing.
