Experimental simulation on Quantinuum and IBM processors of a postselected closed timelike curve protocol that decodes scrambled quantum information before its generation, with success governed by out-of-time-ordered correlations.
As time proceeds backward from T1 to T0, Bob encodes the state |φ0ðB into the joint system HE using the scrambling operation ( U † BH→HE)† = UBH→HE
