Fish-eye lens may entangle pairs of atoms

Nearly 150 years ago, the physicist James Maxwell proposed that a circular lens that is thickest at its center, and that gradually thins out at its edges, should exhibit some fascinating optical behavior. Namely, when light ...

Researchers chart the 'secret' movement of quantum particles

Researchers from the University of Cambridge have taken a peek into the secretive domain of quantum mechanics. In a theoretical paper published in the journal Physical Review A, they have shown that the way that particles ...

Looking for entangled atoms in a Bose-Einstein condensate

Using a Bose-Einstein condensate composed of millions of sodium atoms, researchers at the Georgia Institute of Technology have observed a sharp magnetically-induced quantum phase transition where they expect to find entangled ...

The enigma machine takes a quantum leap

Researchers at the University of Rochester have moved beyond the theoretical in demonstrating that an unbreakable encrypted message can be sent with a key that's far shorter than the message—the first time that has ever ...

Scientists set quantum speed limit

University of California, Berkeley, scientists have proved a fundamental relationship between energy and time that sets a "quantum speed limit" on processes ranging from quantum computing and tunneling to optical switching.
