Is quantum time reversible? 🕜️

For quantum theorist Vlatko Vedral at the University of Oxford, a possible future approach could be to explore a matrix of time in quantum equations.  Rather than just giving the state of a system at a single given time, he argues, you give it for different times as well.  This raises an interesting concept that, as far as quantum mechanics is concerned, it is possible, to undo time for one system while actually not undoing it for other systems. "If we go forward in time, does that really mean that we could equally go backwards in time?," he says.  "Maybe this is what quantum mechanics is telling us."
