NVIDIA (NVDA.O) said it used Germany’s JUPITER supercomputer with 8,192 GPUs to simulate a 104‑qubit fault‑tolerant quantum computing system and validate a magic‑state distillation technique. NVIDIA said the method could reduce the number of physical qubits needed for fault‑tolerant quantum computing by about 90% and cut the simulation time from weeks to days. The company said the advance helps researchers test and optimise quantum designs earlier, but significant technical challenges to practic
