What happened: NVIDIA ran a record quantum computing simulation on the JUPITER exascale supercomputer at Jülich, validating a fault-tolerant technique called magic state cultivation. Key numbers: The approach requires 90% fewer physical qubits than previous methods. JUPITER is Europe's first exascale supercomputer. Why it matters: The result gives quantum hardware companies a reason to rent NVIDIA's cuQuantum and CUDA-Q toolchain before building physical hardware, reframing competitors as near-term customers.
