A team of German physicists has built a fully working version of quantum mechanics that uses only real numbers. Complex ...

A new experiment using ultracold rubidium atoms found that a quantum object in free fall behaves consistently with Einstein's ...

Add Yahoo as a preferred source to see more of our stories on Google. Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless ...

Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at ...

Legendary experiments in 'cat-turning' from the 1850s can teach us about will, control and goal-seeking behaviour Cats are ...

Physicists observed a quantum state change in ultracold atoms. This change matched Einstein's equivalence principle for a ...

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science. Reading time 6 minutes The use of the word “quantum” has become ...

Quantum mechanics doesn't follow these usual rules. Within the laws of quantum mechanics, the results are not fixed until someone observes them. At very tiny scales, particles don't have definite ...

This idea may help address the black hole information paradox, especially the problem that black holes seem to violate a key quantum mechanics rule. A lab experiment with entangled photons showed that ...

Quantum computing refers to using the properties of quantum mechanics for computing purposes. It is still nearly entirely in the research and development phase, but it has massive potential. Quantum ...

The hidden world of quantum mechanics exists at scales many orders of magnitude smaller than living organisms, yet scientists ...
