### A Quantum Trick Implied Eternal Stability. Now the Idea May Be Falling Apart.

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.

### Never-Repeating Tiles Can Safeguard Quantum Information

Two researchers have proved that Penrose tilings, famous patterns that never repeat, are mathematically equivalent to a kind of quantum error correction.

### The Year in Physics

From the smallest scales to the largest, the physical world provided no shortage of surprises this year.

### The Year in Computer Science

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

### The Quest to Quantify Quantumness

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.

### Thirty Years Later, a Speed Boost for Quantum Factoring

Shor’s algorithm will enable future quantum computers to factor large numbers quickly, undermining many online security protocols. Now a researcher has shown how to do it even faster.

### Nobel Prize Honors Inventors of ‘Quantum Dot’ Nanoparticles

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

### Machine Learning Aids Classical Modeling of Quantum Systems

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

### Physicists Observe ‘Unobservable’ Quantum Phase Transition

Measurement and entanglement both have a “spooky” nonlocal flavor to them. Now physicists are harnessing that nonlocality to probe the spread of quantum information and control it.
