NVIDIA says Magic State Cultivation cuts physical-qubit needs by 90%
NVIDIA says researchers used 8,192 GPUs on JUPITER at Germany’s Jülich Supercomputing Centre to simulate a 104-qubit fault-tolerant quantum system. The company described it as the largest comprehensive simulation of such a system. The work examined Magic State Cultivation under hardware noise, with the method requiring 90% fewer physical qubits than earlier approaches.
What to know
- 01
The method was scaled from four GPUs to hundreds on GB200 NVL72 before moving to JUPITER, shortening simulations from weeks to days.
- 02
The simulation used the cuQuantum library and the fault-tolerant logical layer of CUDA-Q.
Why it matters
The simulation findings can help researchers assess noise effects and refine fault-tolerant quantum designs before building hardware.
