Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

Try as they might, scientists can’t truly rid a space or an object of its energy. But what “zero-point energy” really means ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

In the future, quantum computers are anticipated to solve problems once thought unsolvable, from predicting the course of ...

Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary ...

An experiment outlined by a UCL (University College London)-led team of scientists from the UK and India could test whether relatively large masses have a quantum nature, resolving the question of ...

A photon was apparently detected in two places at once in a twist on the classic double-slit experiment, but many physicists ...

In 1971, graduate student Stuart Freedman and postdoctoral fellow John Clauser took over a room in the sub-basement of Birge Hall at the University of California, Berkeley, and built an experiment ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American This was supposed to be an action-packed ...

An experiment outlined by a UCL-led team could test whether relatively large masses have a quantum nature, resolving the question of whether quantum mechanical description works at a much larger scale ...
