### The Computing Pioneer Helping AI See

Alexei Efros has spent his career learning how machines see differently from humans. Now he’s helping to bridge the gap.

### 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.

### The Deep Link Equating Math Proofs and Computer Programs

Mathematical logic and the code of computer programs are, in an exact way, mirror images of each other.

### Tiny Language Models Come of Age

To better understand how neural networks learn to simulate writing, researchers trained simpler versions on synthetic children’s stories.

### The Physical Process That Powers a New Type of Generative AI

Some modern image generators rely on the principles of diffusion to create images. Alternatives based on the process behind the distribution of charged particles may yield even better results.

### 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.

### Alan Turing and the Power of Negative Thinking

Mathematical proofs based on a technique called diagonalization can be relentlessly contrarian, but they help reveal the limits of algorithms.

### The AI Tools Making Images Look Better

Researchers have discovered ways around a fundamental trade-off between accuracy and beauty in digital images.

### Complexity Theory’s 50-Year Journey to the Limits of Knowledge

How hard is it to prove that problems are hard to solve? Meta-complexity theorists have been asking questions like this for decades. A string of recent results has started to deliver answers.
