$NVDA EXPANDS CUDA-Q FOR FAULT-TOLERANT QUANTUM COMPUTING Nvidia has launched CUDA-Q Logical, a new open-source layer designed to help researchers build and test fault-tolerant quantum systems by jointly optimizing algorithms, error correction and hardware requirements. Fermilab says the platform cut one architecture-development workflow from roughly five months to three weeks, a 7x speedup. Iceberg Quantum and Diraq also used it to model 1,000 logical qubits using 150,000 physical qubits, about 10x fewer than Diraq’s previous estimates. These are simulated resource estimates, not operating logical qubits today. Nvidia is also adding QUOPS, a hardware-agnostic benchmark developed by Sandia National Laboratories to compare progress toward utility-scale quantum computing across different platforms. CUDA-Q Logical is already being used by Fermilab, Sandia, Infleqtion, IQM, QCDesign and Quantum Motion. The broader strategy is hardware-agnostic: Nvidia is building the software, GPU and interconnect layer that can sit between different quantum processors and classical supercomputers, regardless of which qubit architecture ultimately wins.
