$NVDAPress releaseOct 19, 2026, 2:00 PM ETRead the release

NVIDIA announced a record 104-qubit simulation of fault-tolerant quantum computing run on JUPITER, Europe's first exascale supercomputer at the Jülich Supercomputing Centre. The work validated a magic-state cultivation approach that uses 90% fewer physical qubits than prior methods, and demonstrated 8,192 NVIDIA GPUs working in tandem via GH200 hardware and the CUDA-Q/cuQuantum software stack.
