Light does not “think” in any human sense. Still, under the right conditions, it can behave in a way that looks uncannily like a memory system.

Stockholm — John Clarke, Michel H. Devoret and John M. Martinis won the Nobel Prize in Physics on Tuesday for research on seemingly obscure quantum tunneling that is advancing digital technology.

Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...

More than 200 years ago, Count Rumford showed that heat isn’t a mysterious substance but something you can generate endlessly through motion. That insight laid the foundation for thermodynamics, the ...

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in probabilities and the other in smooth curves of spacetime. A new line of work argues ...

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 ...

A pair of identical particles swapping places sounds like a small move. In quantum physics, it is a defining one.
