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 ...

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

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

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...

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

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 ...

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

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

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...
