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

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.

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

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 ...

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 ...

But quantum physics won't allow such a thing as zero energy (because of the Uncertainty Principle). Instead, the system has non-zero "ground state" energy with the electron bouncing back and forth ...

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 ...

Space Reality guide: Six problems physics can't explain From the dark energy ripping the cosmos apart to the part consciousness plays in creating reality, quantum physics and cosmology retain many ...
