>> "If you could 3-D print a circuit that manipulates photons instead of electrons, that could pave the way for future applications in light-based computing". This goes hand in hand with the post that made news on HN 3 days ago about "Researchers demonstrate the first single-photon transistor using a semiconductor" source: https://news.ycombinator.com/item?id=17949622 https://news.ycombinator.com/item?id=17949622 Where can we learn more about "light-based computing"?
