NVIDIA simulates record 104-qubit fault-tolerant protocol on JUPITER

NVIDIA ran a 104-qubit simulation of a fault-tolerant quantum processor on Europe's first exascale supercomputer JUPITER, using 8,192 GH200 GPUs at Jülich. The company calls it the most detailed simulation of its kind, validating magic-state cultivation that needs 90% fewer physical qubits.

• The run used 8,192 GH200 GPUs at Jülich Supercomputing Centre
• Magic-state cultivation cuts physical qubit needs by 90%
• The model includes coherent phase errors and qubit leakage
• A 35.2 trillion-amplitude state took 512 TiB of GPU memory
