IBM moves optical computing into the real world

IBM's developed a way of integrating optical computing onto standard silicon chips using standard 90-nanometer semiconductor manufacturing processes.

Could spin logic circuits replace CMOS?

In ten years' time, computers could be a million times more power-efficient than they are today, thanks to a new alternative to today's complementary metal-oxide semiconductor (CMOS) technology.

Cellphones built to see through walls

Researchers at UT Dallas have designed an imager chip that allows mobile phones to see through walls and other objects.

IBM hits terabit speeds with new chip technique
