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

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

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

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 ...

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

Scientists are learning how to temporarily reshape materials by nudging their internal quantum rhythms instead of blasting them with extreme lasers. By harnessing excitons, short-lived energy pairs ...

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

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

Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of ...

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

Experiments reveal that metallic nanoparticles thousands of atoms wide can exist in quantum superposition, providing a ...

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 ...
