Researchers at Cornell University have developed an electronic chip that they describe as a "microwave brain." The simplified chip is analog rather than digital, yet can process ultrafast data and ...

Chander Velu is a professor of innovation and economics at the Institute for Manufacturing, Department of Engineering, University of Cambridge, Cambridge, UK. The race is on to develop commercial ...

Quantum computers are coming. Or, at least, that’s what current predictions say. These machines harness the power of quantum mechanics, the set of rules governing how physics operates at atomic and ...

In a room at the United Kingdom’s University of Plymouth, a Ph.D. student is sitting at a computer, eyes closed as if he’s meditating. On his head is what looks like a black swimming cap, but is ...

While digital computers have become entrenched in our daily lives, a new analog quantum computer offers a stark contrast in both its design and capabilities. A team of physicists from Stanford ...

Britain's hush hush Government Communications Headquarters (GCHQ) intelligence and security organization has released new images never before made public of Colossus, the world's first digital ...

An energy-efficient chip called NeuRRAM fixes an old design flaw to run large-scale AI algorithms on smaller devices, reaching the same accuracy as wasteful digital computers. Artificial intelligence ...

Can a computer learn from the past and anticipate what will happen next, like a human? You might not be surprised to hear that some cutting-edge AI models could achieve this feat, but what about a ...

A computer that uses light rather than digital switches for calculations could help reduce the energy demands of artificial intelligence (AI), according to a new study. The scientists who invented the ...

Soldiers in ancient Greece would send secret dispatches by wrapping a strip of parchment around a staff and writing across it. Their messages could be deciphered only by someone with a staff of the ...
