New computer chips do math with light
Learn about these two futuristic inventions in Science News
Read my story about these new computer chips, published today in Science News.
The photonic devices, just announced in Nature, could pave the way for cheaper AI processing.
Inside this device made by Lightmatter, which is about as wide as a computer keyboard, four photonic chips do math with light. Over 200,000 components manipulate 512 light beams to perform matrix multiplication with greater speed and efficiency than a typical electronic chip.
This is a very cool update to my story that came out back in December, all about computing with light:
A new frontier awaits — computing with light

Today’s tech computes with electricity. But light shows promise as a new means of number-crunching. Could the future of computers be even brighter?
It’s crazy how tech has come this far. Keep up the good work.
