Closed Timelike Curves via Postselection: Theory and Experimental Test of Consistency

Closed Timelike Curves via Postselection: Theory and Experimental Test of Consistency

Closed timelike curves (CTCs) are trajectories in spacetime that effectively travel backwards in time: a test particle following a CTC can interact with its former self in the past. A widely accepted quantum theory of CTCs was proposed by Deutsch. Here we analyze an alternative quantum formulation o...
