Nvidia simulates magic state cultivation on 104 qubits

Nvidia ran a 104-qubit simulation of magic state cultivation on the Jupiter exascale supercomputer, claiming a 90% reduction in qubit overhead versus other methods. The work complements Google's hardware demo on the Willow chip, which cut errors 40-fold and reached 99.99% logical fidelity for T-states.

• Jupiter simulation used 104 qubits and 8,192 GPUs
• Nvidia claims 90% fewer qubits than other methods
• Google's Willow demo cut errors 40-fold at 99.99% fidelity
• Work used CUDA-Q and cuQuantum platforms
