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.

Mark Braverman has spent his career translating thorny problems into the language of information complexity.
Why Claude Shannon Would Have Been Great at Wordle
A bit of information theory can help you analyze — and improve — your Wordle game.
Pondering the Bits That Build Space-Time and Brains
Vijay Balasubramanian investigates whether the fabric of the universe might be built from information, and what it means that physicists can even ask such a question.
Qubits Can Be as Safe as Bits, Researchers Show
A new result shows that quantum information can theoretically be protected from errors just as well as classical information can.
Researchers Defeat Randomness to Create Ideal Code
By carefully constructing a multidimensional and well-connected graph, a team of researchers has finally created a long-sought locally testable code that can immediately betray whether it’s been corrupted.
