Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

An AI model informed by calculations from a quantum computer can better predict the behavior of a complex physical system ...

At the smallest scales of matter, nature behaves in ways that feel almost counterintuitive. Individual particles follow simple rules, but when they interact together, entirely new behaviors can emerge ...

MIT physicists have synthesized a new family of bulk crystals whose electrons behave as though they move in an effectively ...

Here’s what you’ll learn when you read this story: Some of history’s biggest discoveries initially appear to serve no practical purpose. When scientists devised the first working lasers a few decades ...

The quantum revolution in physics — whose 100th anniversary we have just celebrated — taught us that at the most basic level ...
