New model gives quantum theory a shove
SYRACUSE U. (US)—Physicists recently developed a new theoretical model to explain how, under certain rare conditions, more than one electron can simultaneously occupy the same quantum state. (more…)

Physicists prove Einstein wrong
U. TEXAS-AUSTIN (US)—A century after Albert Einstein said we would never be able to observe the instantaneous velocity of tiny particles as they randomly shake and shimmy, so called Brownian motion, physicists have done just that. (more…)

Quantum doughnuts freeze light
U. WARWICK (UK)—Researchers have found a way to use doughnut-shaped byproducts of quantum dots to slow and even freeze light, opening up a wide range of possibilities from reliable and effective light-based computing to the possibility of “slow glass.” (more…)

One step closer to quantum computing
PRINCETON (US)—Physicist Jason Petta may have overcome a major hurdle to designing and constructing a radically new kind of quantum computer. He’s figured out how to manipulate the single electrons that very likely will constitute the new machines’ processing components or “qubits.” (more…)

Quantum ‘dance’ could revolutionize computing
PRINCETON (US)—For years scientists have suspected that atoms placed in certain configurations would trigger electrons to perform a quantum dance of sorts. Now an international team of scientists has observed swarms of electrons spinning in a synchronized quantum dance within a new material. They are hopeful the discovery could be harnessed to transform computing and electronics. (more…)
