When the German computer pioneer Konrad Zuse built the world’s first programmable computer in war time Berlin, it performed floating point arithmetic at a clock speed of between 5 and 10 Hz. The ...

Digital point-and-shoot cameras as well as consumer and prosumer video camcorders have optical zoom, but they also have digital zoom. At the telephoto side of the camera, the computer takes over ...

Are you ready to test your brain with a fun and tricky optical illusion? Here’s a challenge that might leave you scratching your head: three computers and three computer mice are all tangled up ...

Quantum computers run at temperatures just a hair above absolute zero. And keeping them humming along at these temps requires ...

Japanese researchers have helped develop an optical quantum computer that has the potential to drastically reduce the size of the next-generation computer and do even faster calculations. Because ...

Given that the basic computing element of a computer is a transistor — an electronic switching element — and that great progress has been made in all-optical switching and logic, there is an ...
