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

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

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

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

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 ...

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

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 ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

A new experiment could in principle test the quantumness of an object regardless of its mass or energy. An experiment outlined by a UCL (University College London)-led team of scientists from the UK ...

Tests of quantum weirdness and its potential real-world applications have been recognized with the 2022 Nobel Prize in physics. At some level we are all subject to quantum rules that even Albert ...

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 ...
