(Phys.org)—A pair of physicists, one with Tsinghua University in China, the other with Perdue University in the U.S. has come up with what they believe is a viable way to cause a living organism to be in two places at the ...
Quantum computers are experimental devices that promise exponential speedups on some computational problems. Where a bit in a classical computer can represent either a 0 or a 1, a quantum bit, or qubit, can represent 0 and ...

(Phys.org)—Researchers at Sandia National Laboratories in Albuquerque, New Mexico have succeeded in observing the interference of a single atom over a distance far greater than its coherence length using lasers and sequences ...
Elementary particles have a property called "spin" that can be thought of as rotation around their axes. In work reported this week in the journal Physical Review Letters, MIT physicists have imposed a stringent set of traffic ...
