Breakthrough in both quantum/ classical photonic computing: Transistor operating at single-photon intensities controlling powerful beams of light

https://www.eurekalert.org/news-releases/1106958

"using light to control light requires massive power, overcome using avalanche multiplication: single photon strikes silicon, creates single electron triggering avalanche generating up to 1 M new electrons, switching much more powerful probe beam on/ off... uses less energy, room temperature. CMOS compatibility, GHz (potentially 100s)... quantum computing (faster teleportation protocols), classical: not limited by current CPUs' approx. 5 GHz heat/ energy cap... data centers, optical communications, high-performance CPUs"
