Scientists at the Centre for Quantum Technologies (CQT) at the National University of Singapore have shown that a photon's shape affects how it is absorbed by a single atom. They say that this ...

Quantum technologies, devices and systems that operate leveraging quantum mechanical effects, could tackle some tasks more reliably and efficiently than any classical technology could. In recent years ...

Since the discovery of the quantum Hall effect, topological phases of electrons have become a major research area in condensed matter physics. Many topological phases are predicted in lattices with ...

A new study, published in Physical Review Letters, reports that scientists have successfully imaged the formation of ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

Physicists have for the first time observed light drifting sideways in discrete, quantized steps, reproducing a quantum Hall effect that was previously seen only in electrons confined to ultra-thin ...

Researchers at Purdue University have trapped alkali atoms (cesium) on an integrated photonic circuit, which behaves like a transistor for photons (the smallest energy unit of light) similar to ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

Using a laser to place individual rubidium atoms near the surface of a lattice of light, scientists at MIT and Harvard University have developed a new method for connecting particles — one that could ...

Leading light Photon crystals and Mott insulators could soon be made by creating repulsive interactions between photons. (Courtesy: Shutterstock/Dmitriy Rybin) Physicists in the US have come up with a ...
