The name JUFE‑384 is a homage to the original (Josephson‑Underground‑Flux‑Entangler) platform pioneered by the Quantum Frontier Laboratory (QFL) at the University of Zurich in 2022. The “384” suffix denotes the target number of logical qubits that the system can sustain after a full round of surface‑code error correction. JUFE-384
If the early performance metrics hold as the technology matures, JUFE‑384 will usher in the first generation of , opening doors to scientific problems that have, until now, been relegated to the realm of theory. The coming years will test whether the engineering challenges can be met, but the proof‑of‑principle achieved in March 2026 already signals that the quantum future is no longer a distant horizon—it is being built, one flux loop at a time.
