Researchers Build AI That Builds AI

January 25, 2022

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

January 19, 2022

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

January 6, 2022

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

December 23, 2021

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

What Does It Mean for AI to Understand?

December 16, 2021

It’s simple enough for AI to seem to comprehend data, but devising a true test of a machine’s knowledge has proved difficult.

AI Researchers Fight Noise by Turning to Biology

December 7, 2021

Tiny amounts of artificial noise can fool neural networks, but not humans. Some researchers are looking to neuroscience for a fix.

Researchers Defeat Randomness to Create Ideal Code

November 24, 2021

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.

How Quantum Computers Will Correct Their Errors

November 16, 2021

Quantum bits are fussy and fragile. Useful quantum computers will need to use an error-correction technique like the one that was recently demonstrated on a real machine.

Surprising Limits Discovered in Quest for Optimal Solutions

November 1, 2021
