### To Move Fast, Quantum Maze Solvers Must Forget the Past

Quantum algorithms can find their way out of mazes exponentially faster than classical ones, at the cost of forgetting the path they took. A new result suggests that the trade-off may be inevitable.

### How to Build a Big Prime Number

A new algorithm brings together the advantages of randomness and deterministic processes to reliably construct large prime numbers.

### The Lawlessness of Large Numbers

Mathematicians can often figure out what happens as quantities grow infinitely large. What about when they are just a little big?

### Computer Scientists Inch Closer to Major Algorithmic Goal

A new paper finds a faster method for determining when two mathematical groups are the same.

### Neural Networks Need Data to Learn. Even If It’s Fake.

Real data can be hard to get, so researchers are turning to synthetic data to train their artificial intelligence systems.

### Sparse Networks Come to the Aid of Big Physics

A novel type of neural network is helping physicists with the daunting challenge of data analysis.

### Data Compression Drives the Internet. Here’s How It Works.

One student’s desire to get out of a final exam led to the ubiquitous algorithm that shrinks data without sacrificing information.

### Some Neural Networks Learn Language Like Humans

Researchers uncover striking parallels in the ways that humans and machine learning models acquire language skills.

### Secret Messages Can Hide in AI-Generated Media

In steganography, an ordinary message masks the presence of a secret communication. Humans can never do it perfectly, but a new study shows it’s possible for machines.
