The concept of entanglement links far-flung particles. That relationship can prove that someone is in the location they claim ...

Scientists have unveiled a new approach to ultra-secure communication that could make quantum encryption simpler and more ...

Graph (a) shows the two one-dimensional graph states chain (linear cluster) and star on the left, one above the other, and the two-dimensional graph states box and two variants of the ring on the ...

Quantum physicists at the Australian National University (ANU) have achieved a major milestone by directly observing atoms ...

There are few technologies more fundamental to modern life than the ability to control light with precision. From fiber-optic communications to quantum sensors, the manipulation of photons underpins ...

If photons possess more quantum states than expected, it would overhaul our understanding of all particle physics – and now physicists have identified a way to test this radical idea in an experiment.

Earth’s rotation has been measured many times over — but never like this. In a first, scientists used entangled quantum particles called photons to reveal the rate at which the globe spins. The feat ...

Physicists have manipulated individual particles of light, photons, under ultra-stable laboratory conditions. They split a solitary photon into two distinct lower-energy entities, observing with ...

Quantum theory explains the behavior of matter and energy at the smallest scales, like atoms and subatomic particles. Unlike ...
