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 ...

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

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

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 ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different ...

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 ...

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

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

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

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 ...
