(Phys.org)—A team of researchers with members from institutions in the U.S. and Austria has succeeded in building a device that shows a clear step towards the development of an optical single-phonon detector. In their paper ...
(Phys.org)—Physicists have theoretically shown that it is possible to transmit information from one location to another without transmitting energy. Instead of using real photons, which always carry energy, the technique ...
The computing and telecommunications industries have ambitious plans for the future: Systems that will store information in the cloud, analyze enormous amounts of data, and think more like a brain than a standard computer. ...
