Quantum Scientists Have Built a New Math of Cryptography
In theory, quantum physics can bypass the hard mathematical problems at the root of modern encryption. A new proof shows how.
How Distillation Makes AI Models Smaller and Cheaper
Fundamental technique lets researchers use a big, expensive “teacher” model to train a “student” model for less.
Computer Scientists Figure Out How To Prove Lies
An attack on a fundamental proof technique reveals a glaring security issue for blockchains and other digital encryption schemes.
Researchers Uncover Hidden Ingredients Behind AI Creativity
Image generators are designed to mimic their training data, so where does their apparent creativity come from? A recent study suggests that it’s an inevitable by-product of their architecture.
How AI Models Are Helping to Understand — and Control — the Brain
Martin Schrimpf is crafting bespoke AI models that can induce control over high-level brain activity.
New Quantum Algorithm Factors Numbers With One Qubit
The catch: It would require the energy of a few medium-size stars.
How Can AI Researchers Save Energy? By Going Backward.
Reversible programs run backward as easily as they run forward, saving energy in theory. After decades of research, they may soon power AI.
For Algorithms, a Little Memory Outweighs a Lot of Time
One computer scientist’s “stunning” proof is the first progress in 50 years on one of the most famous questions in computer science.
The Fastest Way Yet to Color Graphs
Researchers have devised a scheme for painting the edges of a graph that’s almost as speedy as possible.
