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

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 ...

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 ...

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 ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

Researchers at The Grainger College of Engineering have made a major breakthrough toward building future quantum networks. In a paper published in the research journal Nature in September, researchers ...

In 1921, Albert Einstein received the Nobel Prize in physics for the discovery that light is quantized, interacting with matter as a stream of particles called photons. Since these early days of ...
