When a guitar string is plucked or a playground swing is set in motion, the movement gradually fades away. Physicists call ...

For a century, quantum theory has passed every experimental test, but physicists can’t agree on how to use it to paint a ...

A commemorative survey of quantum physicists revealed a lack of consensus on how best to interpret the strangeness of the quantum world. Credit: NSF/Daniel M. Harris, John W.M. Bush In July 1925 ...

Yunger Halpern’s 2022 book, Quantum Steampunk: The Physics of Yesterday’s Tomorrow, drew public attention to the field. She’s also a science blogger at the website Quantum Frontiers.

“The Age of Entanglement” explores the rich history of quantum physics, a cutting edge field that left some of the brightest scientific minds of the 20th century feeling befuddled and hung over.

Quantum electrodynamics, for example, has been tested against experiments to an accuracy of better than one part in 1,000,000,000,000. It's the most accurate physical theory that we have yet devised.

It suggests that natural quantum fluctuations in space-time, gravitational waves, were sufficient to seed the small density differences that eventually gave rise to galaxies, stars, and planets.

The potential power of quantum computing is enormous and if we are able to actually accomplish it, this will change computing in the same degree that ordinary computing has changed the world since ...

I can’t affect the movement of a tennis ball in China by bouncing one in New York. In the quantum world, where physicists study the behaviors of individual atoms and their even smaller parts ...

These analog quantum simulators are designed to solve problems that even the fastest, most efficient digital quantum computers can’t. But we aren’t talking about room-sized computers like you ...
