'Handwritten' numbers generated by integrated optical computing chip
An illustration of an integrated optical computing chip and "handwritten" numbers it generated. The chip contains an artificial neural network that can learn how to write in its own distinct style. The system uses "noise" (stray photons from lasers and thermal background radiation) to augment its creative capabilities and is approximately 10 times faster than comparable conventional digital computers and more energy efficient.
