Can quantum systems become more disordered, as thermodynamics would predict? Yes, they can - if a proper definition of "entropy" is used. It is one of the most important laws of nature that we know: ...

Two physicists at the University of Stuttgart have proven that the Carnot principle, a central law of thermodynamics, does ...

Could our universe be expanding then shrinking back into a tiny point, reliving a kind of big bang over and over again? Probably not, according to a mathematical analysis that argues that the laws of ...

This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum mechanics was proposed. The theory hardly needed the extra publicity, though ...

Australian technology has delivered a live quantum-secure link, a breakthrough that promises to future-proof critical data ...

The 2025 Nobel Prize in physics honors three quantum physicists—John Clarke, Michel H. Devoret and John M. Martinis—for their ...

In the strange, often unintuitive world of quantum physics, one mystery has stood out for decades: Can quantum entanglement be manipulated in a reversible way, like energy in a perfect heat engine?

John Clarke, Michel H. Devoret and John M. Martinis were recognized for work that made behaviors of the subatomic realm ...

During the 2024-25 school year, students in Southern Adventist University’s physics club taught lessons about the basics of Quantum Information Science and Technology (QUIST) at three local schools.

For the first time, scientists have observed electrons in graphene behaving like a nearly perfect quantum fluid, challenging a long-standing puzzle in physics. By creating ultra-clean samples, the ...

A Vermont research team has cracked a 90-year-old puzzle, creating a quantum version of the damped harmonic oscillator. By reformulating Lamb’s classical model, they showed how atomic vibrations can ...

A plucked guitar string can vibrate for seconds before falling silent. A playground swing, emptied of its passenger, will gradually come to rest. These are what physicists call "damped harmonic ...
