Light can do more than illuminate a material. In some cases, it can temporarily change how electrons move through it. That ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

Light and matter can remain at separate temperatures even while interacting with each other for long periods, according to ...

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

Scientists have shown that it may be possible to transform materials simply by triggering internal quantum ripples rather ...

Scientists are learning how to temporarily reshape materials by nudging their internal quantum rhythms instead of blasting ...

Quantum physicists are edging closer to a kind of controlled transmutation, not of lead into gold, but of one electronic reality into another. By steering exotic entities called excitons, researchers ...

In 1925, German physicist Werner Heisenberg published a paper on quantum mechanics, upending classical physics and launching the world into the quantum age.

Quantum entanglement happens when two particles become interconnected and share a single state. Scientists have measured how ...

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

This episode of the Physics World Weekly podcast features Alex May, whose research explores the intersection of quantum gravity and quantum information theory. Based at Canada’s Perimeter Institute ...
