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 ...

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

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

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 ...

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 ...

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

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

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