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 ...

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 ...

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 ...

Using the world's most powerful particle accelerator, the Large Hadron Collider, scientists have found that the quark-gluon ...

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 ...

Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

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 ...

"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 ...

Physicists want to ramp up their efforts to weigh neutrinos, which are perhaps the most mysterious of all elementary particles. Currently, only one experiment in the world has a shot at making such a ...

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, it could upend laws of physics that have held fast for ...
