The quantum arrow of time can be reversed, physicists show
SMRTR summary
Physicists have found a theoretical way to reverse time's direction in quantum systems by using precise control sequences called Hamiltonians, which flip events backward — like an egg uncracking. This breakthrough could help prevent information loss in quantum computers, though perfect measurement technology is still needed to test it experimentally.
