Quantum technologies, devices and systems that operate leveraging quantum mechanical effects, could tackle some tasks more ...

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 ...

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 ...

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 ...

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 ...

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, ...

Photons, particles that represent a quantum of light, have shown great potential for the development of new quantum technologies. More specifically, physicists have been exploring the possibility of ...

Shuo Sun’s research studies light-matter interactions at the quantum limit where single photons can interact with single atoms. The strong atom-photon interactions lead to two important applications ...

Since these early days of quantum mechanics, it is known that photons also possess momentum. The photon's ability to transfer momentum was used in a novel approach by scientists to observe a ...
