Quantum physics

Time is all around us: in the language we use, in the memories we revisit and in our predictions of the future. But what exactly is it? The physicist and Nobel laureate Frank Wilczek joins Steve Strogatz to discuss the fundamental hallmarks of time.

A series of advances seemed to promise the impossible: the existence of quantum states that would never, ever fall into disarray. But physicists are now discovering that the pull of disorder may not be so easily overcome.

In an atomically thin stack of semiconductors, a mechanism unseen in any natural substance causes electrons’ spins to align.

Artificial intelligence learned how to generate text and art better than ever before, while computer scientists developed algorithms that solved long-standing problems.

A century ago, the Stern-Gerlach experiment established the truth of quantum mechanics. Now it’s being used to probe the clash of quantum theory and gravity.

What makes a quantum computer more powerful than a classical computer? It’s a surprisingly subtle question that physicists are still grappling with, decades into the quantum age.

The Nobel Prize in Chemistry has been awarded to three researchers who harnessed the quantum behaviors of semiconductor nanocrystals.

The development of attosecond pulses of light allowed researchers to explore the frame-by-frame movement of electrons.

By using “classical shadows,” ordinary computers can beat quantum computers at the tricky task of understanding quantum behaviors.
