Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

Communication is a two-way street. Thanks to quantum mechanics, that adage applies even if you’ve got only one particle to transmit messages with. Using a single photon, or particle of light, two ...

Using a groundbreaking new technique, researchers have unveiled the first detailed image of a photon — a single particle of light — ever taken. When you purchase through links on our site, we may earn ...

Some things are easier to achieve if you're not alone. As researchers from the University of Rostock, Germany have shown, ...

Classically, light can be thought of in two ways: either as a particle or a wave. But what is it really? Well, the ‘observer effect’ makes that question kind of difficult to answer. So before we get ...

What if you could behave like the crew on the Starship Enterprise and teleport yourself home or anywhere else in the world? As a human, you're probably not going to realize this any time soon; if ...

Two ghostlike particles, neutrinos and photons, are emerging as unlikely combatants in a quiet revolution in physics. New calculations suggest these nearly intangible entities may interact in extreme ...

Photon duality remains a paradox because the photon is regarded as a simple, unitary object in space. Equally bad, massless radiation is interpreted via concepts drawn from mass-based physics. The ...

Until recently, scientists didn't think it could be done. They thought the fundamental laws of physics would forbid it. But a persistent group of scientists at the University of Warsaw have now ...
