The ALPS (Any Light Particle Search) experiment, which stretches a total length of 250 metres, is looking for a particularly light type of new elementary particle. Using twenty-four recycled ...

A team of quantum physicists has taken a concept that once lived purely in equations and turned it into hardware reality, creating a single particle of light that behaves as if it occupies 37 distinct ...

Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, revealing light-like particles with a strikingly high-dimensional character. By ...

Long tubes, strong magnets, and bright lasers. Is that all it takes to entice the shyest particles in the universe to reveal themselves? Physicists working on the ALPS II experiment certainly hope so, ...

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." The Greenberger–Horne–Zeilinger (GHZ) paradox describes how quantum theory cannot be described by local ...

New measurements from an experiment near the top of an extinct Mexican volcano have placed a stringent new limit on whether light can exceed the universe’s well-known top speed. Physicists have ...

Until quite recently, creating a hologram of a single photon was believed to be impossible due to fundamental laws of physics. However, scientists at the Faculty of Physics, University of Warsaw, have ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light ...

Results from KATRIN and MicroBooNE strongly disfavour a light sterile-neutrino explanation of longstanding anomalies.
