When old tech dies, it usually stays dead. No one expects rotary phones or adding machines to come crawling back from oblivion. Floppy diskettes, VHS tapes, cathode-ray tubes—they shall rest in peace.

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 ...

Physicists have invented a new type of analog quantum computer that can tackle hard physics problems that the most powerful digital supercomputers cannot solve. New research published in Nature ...

Machine learning is another area where quantum computers may accelerate progress. This could happen indirectly, by speeding up subroutines in digital computers, or directly if quantum computers can be ...

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 ...

CAMBRIDGE, U.K. – A small Microsoft Research team had lofty goals when it set out four years ago to create an analog optical computer that would use light as a medium for solving complex problems.

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 ...

When thinking of the first PCs, most of us might imagine something like the Apple I or the TRS-80. But even before that, there were a set of computers that often had no keyboard, or recognizable ...

For six or seven decades, computers have been based on processing electronic 1s and 0s. Now, computer scientists are breaking out of that paradigm in strange new directions, as they seek new ways to ...

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 ...

In June, an IBM computing executive claimed quantum computers were entering the “utility” phase, in which high-tech experimental devices become useful. In September, Australia’s Chief Scientist Cathy ...
