quantum physics

Quantum computers may derive their power from the “magical” way that properties of particles change depending on the context.

The second law of thermodynamics is among the most sacred in all of science, but it has always rested on 19th century arguments about probability. New arguments trace its true source to the flows of quantum information.

By resolving a paradox about light in a box, researchers hope to clarify the concept of energy in quantum theory.

Einstein’s description of curved space-time doesn’t easily mesh with a universe made up of quantum wavefunctions. Theoretical physicist Sean Carroll discusses the quest for quantum gravity with host Steven Strogatz.

Throwing out data seems to make measurements of distances and angles more precise. The reason why has been traced to Heisenberg’s uncertainty principle.

Thanks to the power of fluctuation relations, physicists are taking the second law of thermodynamics to settings once thought impossible.

Physicists are using quantum math to understand what happens when black holes collide. In a surprise, they’ve shown that a single particle can describe a collision’s entire gravitational wave.

If only scientists understood exactly how electrons act in molecules, they’d be able to predict the behavior of everything from experimental drugs to high-temperature superconductors. Following decades of physics-based insights, artificial intelligence systems are taking the next leap.

The same phenomenon by which an opera singer can shatter a wineglass also underlies the very existence of subatomic particles.
