Researchers have demonstrated that quantum entanglement can link atoms across space to improve measurement accuracy. By ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

Entangled atoms, separated in space, are giving scientists a powerful new way to measure the world with stunning precision.

Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

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 ...

Until now, creating quantum superpositions of ultra-cold atoms has been a real headache, too slow to be realistic in the laboratory. Researchers at the University of Liège have now developed an ...

A NOON state is a superposed quantum state where N particles are in one state "at the same time" and in another "at the same time". Here, the particles are trapped in two wells, within a trap formed ...
