How Public Key Cryptography Really Works, Using Only Simple Math
The security system that underlies the internet makes use of a curious fact: You can broadcast part of your encryption to make your information much more secure.
Debate May Help AI Models Converge on Truth
How do we know if a large language model is lying? Letting AI systems argue with each other may help expose the truth.
Computer Scientists Establish the Best Way to Traverse a Graph
Dijkstra’s algorithm was long thought to be the most efficient way to find a graph’s best routes. Researchers have now proved that it’s “universally optimal.”
‘Quantum Memory’ Proves Exponentially Powerful
Researchers are exploring new ways that quantum computers will be able to reveal the secrets of complex quantum systems.
The Computer Scientist Who Builds Big Pictures From Small Details
To better understand machine learning algorithms, Lenka Zdeborová treats them like physical materials.
Computer Scientists Combine Two ‘Beautiful’ Proof Methods
Three researchers have figured out how to craft a proof that spreads out information while keeping it perfectly secret.
How ‘Embeddings’ Encode What Words Mean — Sort Of
Machines work with words by embedding their relationships with other words in a string of numbers.
Novel Architecture Makes Neural Networks More Understandable
By tapping into a decades-old mathematical principle, researchers are hoping that Kolmogorov-Arnold networks will facilitate scientific discovery.
Computer Scientists Prove That Heat Destroys Quantum Entanglement
While devising a new quantum algorithm, four researchers accidentally established a hard limit on entanglement.
