Computers

Reversible programs run backward as easily as they run forward, saving energy in theory. After decades of research, they may soon power AI.

The brain’s astounding cellular diversity and networked complexity could show how to make AI better.

While some fret about technology’s social impacts, Raj Reddy still believes in the power of artificial intelligence to improve lives.

Our computers can get a lot more done when they share the load with other machines.

You don’t need 0s and 1s to perform computations, and in some cases it’s better to avoid them.

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

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

Researchers prove that navigating certain systems of vectors is among the most complex computational problems.

What makes a quantum computer more powerful than a classical computer? It’s a surprisingly subtle question that physicists are still grappling with, decades into the quantum age.
