Juq-716 🆕 Quick

Key takeaway: JUQ‑716 is the only commercial silicon process that in a single PDK. Competing offerings still rely on post‑fabrication “add‑on” solutions (e.g., external SFQ chips, custom packaging).

Enter – a purpose‑built semiconductor platform that reconciles the ultra‑low‑noise, low‑power, and cryogenic demands of quantum control while still leveraging the massive ecosystem of advanced CMOS manufacturing. juq-716
