(PhysOrg.com) -- While the optical laser celebrated its 50th anniversary earlier this year, some scientists have been working on a new type of coherent beam amplifier for sound rather than light. Scientists theorize that ...
(PhysOrg.com) -- By precisely shaking a container of shallow water, researchers have observed wave behavior that has never been seen before. In a new study, Jean Rajchenbach, Alphonse Leroux, and Didier Clamond of the University ...
(Phys.org)—As understood in the field of quantum mechanics, objects are able to exist in more than one state at a time, a property known as superposition. Measuring such states is a challenge however, as doing so causes ...
(PhysOrg.com) -- The three large Japanese manufactures, Hitachi, Panasonic Corp., and Toshiba Corp, have announced that they are developing radio frequency (RF) transceiver ICs in the 60GHz band. All three manufactures plan ...
(Phys.org) —A research team with members from the U.S. and Italy has succeeded in building an integrated graphene digital circuit that is able to function at gigahertz frequencies. In their paper published in the journal ...
In the far future, superconducting quantum bits might serve as components of high-performance computers. Today already do they help better understand the structure of solids, as is reported by researchers of Karlsruhe Institute ...
