### Finally, a Fast Algorithm for Shortest Paths on Negative Graphs

Researchers can now find the shortest route through a network nearly as fast as theoretically possible, even when some steps can cancel out others.

### New Algorithm Closes Quantum Supremacy Window

Random circuit sampling, a popular technique for showing the power of quantum computers, doesn’t scale up if errors go unchecked.

### The Year in Computer Science

Computer scientists this year learned how to transmit perfect secrets, why transformers seem so good at everything, and how to improve on decades-old algorithms (with a little help from AI).

### After a Quantum Clobbering, One Approach Survives Unscathed

A quantum approach to data analysis that relies on the study of shapes will likely remain an example of a quantum advantage — albeit for increasingly unlikely scenarios.

### Crucial Computer Program for Particle Physics at Risk of Obsolescence

Maintenance of the software that’s used for the hardest physics calculations rests almost entirely with a retiree. The situation reveals the problematic incentive structure of academia.

### AI Reveals New Possibilities in Matrix Multiplication

Inspired by the results of a game-playing neural network, mathematicians have been making unexpected advances on an age-old math problem.

### The AI Researcher Giving Her Field Its Bitter Medicine

Anima Anandkumar wants computer scientists to move beyond the matrix, among other challenges.

### Quantum Algorithms Conquer a New Kind of Problem

Computer scientists have found a new type of problem that quantum computers can solve dramatically faster than their classical counterparts.

### By Exploring Virtual Worlds, AI Learns in New Ways

Intelligent beings learn by interacting with the world. Artificial intelligence researchers have adopted a similar strategy to teach their virtual agents new tricks.
