Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

Two ghostlike particles, neutrinos and photons, are emerging as unlikely combatants in a quiet revolution in physics. New ...

A new study takes the GHZ paradox, which describes how quantum theory can't be described by local realistic descriptions, to new heights.

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Using the Super Proton Synchrotron, the team created beams of electron-positron pairs and passed them through a meter-long region of plasma. This setup served as a scaled laboratory version of a ...

Physicists are learning to treat light not as an untouchable beam that simply passes through matter, but as something that can be bent, cloaked, and sculpted at scales smaller than a single wavelength ...

Shaped quantum light is turning ordinary photons into powerful tools for the future of technology.

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported the first ...

This episode of the Physics World Weekly podcast features Alex May, whose research explores the intersection of quantum ...

Gravitational wave facilities measure distortions in the fabric of spacetime down to 10 quadrillionths the width of a hair – small enough to hear interference from particles popping in and out of ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...
