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 ...

Two of the forefathers of quantum theory, Albert Einstein and Niels Bohr, had a famous argument over whether light is a wave ...

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 ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. The Greenberger–Horne–Zeilinger (GHZ) paradox describes how quantum theory cannot be described by local realistic descriptions. A ...

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 ...

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 ...

Two extremely precise experiments agree with a previously shocking measurement of just how big the proton is, which may help ...

Physicists at multiple institutions are compressing particle accelerators from facility-scale machines stretching hundreds of ...
