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 ...

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

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

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

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

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

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

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

Technological devices are getting ever smaller, but as they approach the scale at which quantum physics matters, our understanding of how they interact with their environment evaporates. James Millen ...

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