Quantum mechanics replaced the clockwork certainty of classical physics with something far stranger: a framework in which particles do not follow single, predictable paths but instead exist as clouds ...

Researchers have demonstrated that a nanoparticle of 7,000 sodium atoms can act as a wave, creating a record-setting superposition.

Add Yahoo as a preferred source to see more of our stories on Google. This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum ...

They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...

“We wouldn’t have a quantum computer if everyone was like me,” he says. Copenhagen still reigns supreme Over the past century, researchers have proposed many ways to interpret the reality behind the ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

If true, the idea would blow past one of physics’ most sacred limits: that parallel versions of reality can never talk to each other. And if information could leak between outcomes, it could mean ...

As Joe Howlett points out, "the Schrödinger equation remains physicists’ foremost window into the quantum realm. It tells scientists how that strange world works; that is, how quantum objects interact ...
