NVIDIA and Jülich Run 104-Qubit Magic State Cultivation Simulation on JUPITER Supercomputer
NVIDIA and Jülich Supercomputing Centre simulated a 104-qubit fault-tolerant quantum computing experiment on the JUPITER exascale supercomputer, using 8,192 NVIDIA GH200 Grace Hopper Superchips. The simulation validated a magic state cultivation protocol that could reduce the number of physical qubits needed for fault tolerance. The work is described in an NVIDIA technical report.

Magic state cultivation validated by this simulation could be adopted in near-term error-corrected quantum processors, lowering physical qubit overhead and bringing 100-logical-qubit demonstrations within reach in the next two years.
The simulated 104-qubit fault-tolerant protocol is within the scale of existing superconducting and trapped-ion prototypes, and the exascale simulation provides credible evidence that the protocol works beyond small toy models. If hardware noise and control imperfections do not negate the overhead reduction, teams may prioritise implementing it on real devices.
