### The Best Qubits for Quantum Computing Might Just Be Atoms

In the search for the most scalable hardware to use for quantum computers, qubits made of individual atoms are having a breakout moment.

### How Chain-of-Thought Reasoning Helps Neural Networks Compute

Large language models do better at solving problems when they show their work. Researchers are beginning to understand why.

### Physicists Finally Find a Problem for Quantum Computers Alone

Researchers have shown that a problem relating to the energy of a quantum system is easy for quantum computers but hard for classical ones.

### New Breakthrough Brings Matrix Multiplication Closer to Ideal

By eliminating a hidden inefficiency, computer scientists have come up with a new way to multiply large matrices that’s faster than ever.

### How Selective Forgetting Can Help AI Learn Better

Erasing key information during training results in machine learning models that can learn new languages faster and more easily.

### Never-Repeating Tiles Can Safeguard Quantum Information

Two researchers have proved that Penrose tilings, famous patterns that never repeat, are mathematically equivalent to a kind of quantum error correction.

### How Quickly Do Large Language Models Learn Unexpected Skills?

A new study suggests that so-called emergent abilities actually develop gradually and predictably, depending on how you measure them.

### Scientists Find Optimal Balance of Data Storage and Time

Seventy years after the invention of a data structure called a hash table, theoreticians have found the most efficient possible configuration for it.
