Discovery of bistable nanocrystals promises faster, more energy-efficient optical computing

Optically bistable nanocrystals can store information that is written and read entirely through light, making them useful for building small and scalable optical memory units. These nanocrystals are controlled by a laser. One provides continuous power and the other triggers the light emission after a short pulse. This feature mimics the operation of electronic transistors and paves the way for…
