First Electronic-Photonic Quantum Chip Created In Commercial Foundry
It's "a milestone for scalable quantum technologies," according to the announcement from Boston University. Scientists from Boston University, UC Berkeley, and Northwestern University "reported the world's first electronic-photonic-quantum system on a chip, according to a study published in Nature E...
"This is a small step on that path — but an important one, because it shows we can build repeatable, controllable quantum systems in commercial semiconductor foundries." The system combines quantum light sources and stabilizing electronics using a standard 45-nanometer semiconductor manufacturing process to produce reliable streams of correlated photon pairs (particles of light) — a key resource for emerging quantum technologies. Just as electronic chips are powered by electric currents, and optical communication links by laser light, future quantum technologies will require a steady stream of quantum light resource units to perform their functions.
