Building up on their last year’s breakthrough “time reversal” experiment, two researchers from the Moscow Institute of Physics and Technology and Argonne National Laboratory have published a new theoretical study in Communications Physics. While their previous paper dealt with a predefined quantum state, this time the physicists have devised a way to time-reverse the evolution of an object in…
