First Electronic-Photonic Quantum Chip Created in a Commercial Foundry

In a milestone for scalable quantum technologies, scientists from Boston University, UC Berkeley, and Northwestern University have reported the world’s first electronic–photonic–quantum system on a chip, according to a study published in Nature Electronics. 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 — a key resource for emerging quantum technologies. The advance paves the way for mass-producible “quantum light factory” chips and large-scale quantum systems built from many such chips working together.
