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

Researchers have demonstrated how quantum mechanical entanglement can be used to measure several physical parameters simultaneously with greater precision.

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

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

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 ...

Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold new line of research now argues that gravity is not fundamental at all, ...

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 ...

Physicists uncover a universal limit on timekeeping precision, proving that anything from heartbeats to ocean waves can be a ...

Neutrino physics. “Movies” of quantum phenomena. Many-body problems. New-to-nature catalytic reactions. These are just a few of the hot fields of research where UC Santa Barbara’s junior faculty are ...

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 ...
