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 ...

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.

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 ...

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 ...

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.

Computers and various digital devices are used throughout organizations large and small to operate daily business. The fundamental role of digital systems in business brings with it serious security ...

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 ...
