Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: ...

The many worlds interpretation (MWI) of quantum mechanics, proposed by Hugh Everett in 1957, posits that reality consists of multiple worlds where every possible quantum outcome occurs. This contrasts ...

Quantum physicists at the Australian National University (ANU) have achieved a major milestone by directly observing atoms ...

A cloud of helium atoms split, scattered and fell under gravity, yet still behaved as if its parts were linked. That is the ...

For the first time, scientists have observed quantum entanglement in the momentum of massive particles. The result, decades ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in ...

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

The Princeton Quantum Initiative’s Ph.D. program is helping pioneer a field that promises to define the next era of discovery ...
