NVIDIA Simulates 104-Qubit Fault-Tolerant Quantum System on JUPITER
NVIDIA announced a 104-qubit fault-tolerant quantum simulation run on Jülich's JUPITER supercomputer, validating an approach it says needs 90% fewer qubits.
What you need to know
NVIDIA announced a 104-qubit simulation of a fault-tolerant quantum processor on JUPITER, Europe's first exascale supercomputer at Jülich Supercomputing Centre. The company described it as the largest comprehensive simulation of its kind, modeling realistic noise and validating a magic-state cultivation approach it says uses 90% fewer physical qubits than prior methods.
- The 104-qubit simulation ran on NVIDIA GH200 superchips at Jülich Supercomputing Centre.
- NVIDIA says the approach requires 90% fewer physical qubits than previous methods.
- Development used a GB200 NVL72 system at NVIDIA's Accelerated Quantum Research Center before scaling to 8,192 GPUs on JUPITER.
What the simulation modeled
NVIDIA said its researchers simulated magic-state cultivation, a method for producing the special qubit arrangements that fault-tolerant quantum computers consume during computation. Qubits are inherently noisy, so simulating the process under realistic noise conditions matters for judging how a design would perform.
The company called the 104-qubit run the largest comprehensive simulation of a fault-tolerant quantum processor to date. An earlier Jülich effort modeled 50 qubits under ideal, noiseless conditions, according to the announcement.
Scaling and purpose
Because memory requirements can grow exponentially with qubit count, large simulations exceed conventional systems. NVIDIA said researchers developed and tested methods on a GB200 NVL72 system at its Accelerated Quantum Research Center, scaling from four GPUs to hundreds before moving to 8,192 GPUs on JUPITER.
The company said the work cut a weekslong simulation to days. It framed such simulation as a way to refine designs before hardware is built, with potential applications in drug discovery, financial modeling and materials science. The simulations used NVIDIA cuQuantum software and the CUDA-Q platform's fault-tolerant logical layer.
How many qubits did NVIDIA's simulation model, and where did it run?
