Anima Anandkumar wants computer scientists to move beyond the matrix, among other challenges.

Computer scientists have found a new type of problem that quantum computers can solve dramatically faster than their classical counterparts.

Intelligent beings learn by interacting with the world. Artificial intelligence researchers have adopted a similar strategy to teach their virtual agents new tricks.

Computer scientists can now solve a decades-old problem in practically the time it takes to write it down.

Why verify every line of a proof, when just a few checks will do?

Finding out whether a question is too difficult to ever solve efficiently depends on figuring out just how hard it is. Researchers have now shown how to do that for a major class of problems.

Researchers say we’re on the cusp of “GoPro physics,” where a camera can point at an event and an algorithm can identify the underlying physics equation.

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.

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.
