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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

When fundamental particles are heavier or lighter than expected, physicists' understanding of the universe can tip into the ...

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 ...

An icon in the shape of a lightning bolt. Impact Link An underground vat of liquid xenon in Italy may have just detected a new particle, born in the heart of the sun. If that's indeed what happened, ...
