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.
After applying the decoding operation U † to the joint system HE, we perform quantum state tomography (i.e., single-qubit Pauli measurements [ 74]) on qubit B before T1
