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.
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.
Google Researcher, Long Out of Math, Cracks Problem About Sets
On nights and weekends, Justin Gilmer attacked an old question in pure math using the tools of information theory.
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).
New Entanglement Results Hint at Better Quantum Codes
A team of physicists has entangled three photons over a considerable distance, which could lead to more powerful quantum cryptography.
The Computer Scientist Who’s Boosting Privacy on the Internet
Harry Halpin wants our internet conversations to be more private. He’s helped create a new kind of network that might make it possible.
How Mathematical Curves Enable Advanced Communication
A simple geometric idea has been used to power advances in information theory, cryptography and even blockchain technology.
How Shannon Entropy Imposes Fundamental Limits on Communication
What’s a message, really? Claude Shannon recognized that the elemental ingredient is surprise.
The Scientist Who Developed a New Way to Understand Communication
Mark Braverman has spent his career translating thorny problems into the language of information complexity.
