Compared with IBM’s Eagle (127 qubits) and Google’s Sycamore‑v2 (433 qubits), the JUQ‑703‑UC offers more than 5× the physical qubits while maintaining comparable or superior gate fidelities. Its biggest differentiator is the on‑chip error‑correction co‑processor, which offloads syndrome extraction and decoding to an embedded ASIC, reducing latency from the typical 10–20 µs (CPU‑hosted) to sub‑µs. | Benchmark | Metric | JUQ‑703‑UC Result |
