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

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

A 'boom' of light that appears when a particle exceeds the speed of light set by a medium could, in other contexts, signal a ...

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, ...

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

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

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 ...
