### Cryptographers Achieve Perfect Secrecy With Imperfect Devices

For the first time, experiments demonstrate the possibility of sharing secrets with perfect privacy — even when the devices used to share them cannot be trusted.

### AI Overcomes Stumbling Block on Brain-Inspired Hardware

Algorithms that use the brain’s communication signal can now work on analog neuromorphic chips, which closely mimic our energy-efficient brains.

### Machine Learning Becomes a Mathematical Collaborator

Two recent collaborations between mathematicians and DeepMind demonstrate the potential of machine learning to help researchers generate new mathematical conjectures.

### Computer Scientists Prove Why Bigger Neural Networks Do Better

Two researchers show that for neural networks to be able to remember better, they need far more parameters than previously thought.

### Machine Learning Gets a Quantum Speedup

Two teams have shown how quantum approaches can solve problems faster than classical computers, bringing physics and computer science closer together.

### Researchers Build AI That Builds AI

By using hypernetworks, researchers can now preemptively fine-tune artificial neural networks, saving some of the time and expense of training.

### Computer Scientists Eliminate Pesky Quantum Computations

For years, intermediate measurements made it hard to quantify the complexity of quantum algorithms. New work establishes that those measurements aren’t necessary after all.

### 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.

### The Year in Math and Computer Science

Mathematicians and computer scientists answered major questions in topology, set theory and even physics, even as computers continued to grow more capable.
