Scientists just demonstrated light driven computing at 10,000 GHz over 100× faster than today’s processors. Ultrafast computing breakthrough In a new study, researchers showed that ultrafast laser pulses can perform logic operations in a 2D semiconductor called tungsten disulfide. Instead of traditional transistors switching with electrical current, the system uses light to control electron valley states, a technique known as valleytronics. By manipulating these states with femtosecond laser pulses (10⁻¹⁵ seconds), the team achieved logical switching frequencies above 10 terahertz. For comparison, today’s processors operate at only 3–5 GHz 👀! This experiment shows that future computers could potentially operate hundreds to thousands of times faster by combining photonics and quantum materials. while still a laboratory demonstration, the research points toward a future of light driven computing far beyond silicon’s limits.



DTK 我还没还呢,怎么就感谢归还了……?




I'm joining @OpenAI at the end of the month, and I can't wait to get started! I'll be working on everything related to Codex, bringing what I learned building Codex Monitor, and working with the developer experience team with @romainhuet!
