Examples like Intel's Loihi chips tend to get competitive performance out of far lower clock speeds and energy use, but they ...

We all know, at least intellectually, that our computers are all built with lots of tiny transistors. But beyond that it’s a little hard to describe. They’re printed on a silicon wafer somehow ...

The idea of an optical transistor — and the associated optical logic circuits that may follow — conjures images of light controlling light in some sparkling, transparent computer. This dream ...
