What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred ...

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether in a physics class, in the lab, or in popular science writing, is left ...

Everyone has their favourite example of a trick that reliably gets a certain job done, even if they don’t really understand why. Back in the day, it might have been slapping the top of your television ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

At Aalto University in Finland, two physicists believe they may have cracked a puzzle that has defied generations of scientists: how to reconcile the physics of the very big with the physics of the ...

The first reported demonstration of “unconditional” quantum advantage has little practical value—but that's perhaps why it ...
