Quantum entanglement happens when two particles become interconnected and share a single state. Scientists have measured how ...

What if you could create new materials just by shining a light at them? To most, this sounds like science fiction or alchemy, ...

“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral ...

Physicists have revealed a quantum state once thought impossible, where topology emerges even without particle-like electrons ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the smallest scales, erasing information is not free, it consumes energy and ...

Physicists have long relied on the idea that electrons behave like tiny particles zipping through materials, even though ...

Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

Long considered a serious technical challenge, superradiance could actually help quantum devices go even further. Quantum timekeeping comes with the paradoxes of quantum mechanics, a new study ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

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 ...
