NVIDIA Completes 104-Qubit Fault-Tolerant Quantum Computing Simulation, Claims Required Qubits Can Be Reduced by 90%

NVIDIA utilized 8192 GPUs on JUPITER, Europe's first exascale supercomputer hosted at the Jülich Supercomputing Center in Germany, to complete a full simulation of a 104-qubit fault-tolerant quantum processor, marking the largest full-scale simulation of its kind to date. This simulation validated magic state cultivation, one of the leading mainstream approaches for fault-tolerant quantum computing. NVIDIA states that this method reduces the number of required qubits by 90% compared to prior approaches, and cuts down development-phase simulation runtime from weeks to mere days. The company notes that such simulations are expected to accelerate the timeline for delivering practical quantum computers by several years.
