IBM’s announcement that they had produced the world’s smallest computer back in March raised a few eyebrows at the University of Michigan, home of the previous champion of tiny computing. Now, the Michigan team has gone even smaller, with a device that measures just 0.3 mm to a side — dwarfed by a grain of…
Ultrashort Light Pulses Make Faster Computers
Extremely short, configurable “femtosecond” pulses of light demonstrated by an international team could lead to future computers that run up to 100,000 times faster than today’s electronics. The researchers, including engineers at the University of Michigan, showed that they could control the peaks within the laser pulses and also twist the light. The method moves…
