(Phys.org) —It's been a remarkable week for physics work—first a research team claims to have accurately 'teleported' quantum information ten feet, and report that they did so with 100 percent accuracy. If the claims ...
When it comes to looking at reality from the subatomic perspective of quantum theory, many physicists are nearly as much in the dark as the average person on the street.
