NVIDIA Expands Open Source CUDA-Q Platform for Fault-Tolerant Quantum Computing
nvidia ·
NVIDIA announced an expansion of its open source CUDA-Q platform with a new orchestration layer called CUDA-Q Logical, designed for developing applications on fault-tolerant quantum computers. This layer provides a programmable and verifiable approach to designing and testing fault-tolerant quantum applications in areas such as drug discovery, financial modeling, and materials development. Fermi National Accelerator Laboratory used CUDA-Q Logical to accelerate fault-tolerant architecture development from five months to three weeks, achieving a 7x speedup. Sandia National Laboratories developed a new benchmark called QUOPS, now available in CUDA-Q, to measure progress toward utility-scale quantum computing, with early results for QPUs from Google, IBM, and Quantinuum. Iceberg Quantum used CUDA-Q Logical to model a fault-tolerant architecture for Diraq's qubits, reducing the estimated physical qubits needed for 1,000 logical qubits by roughly 10x compared to previous estimates. Other organizations adopting CUDA-Q Logical include Infleqtion, IQM Quantum Computers, QCDesign Quantum Motion, and Sandia National Laboratories. The broader ecosystem is also integrating NVIDIA technologies like NVQLink for quantum-GPU supercomputing and NVIDIA Ising for qubit calibration, with companies such as Anyon Computing, Quandela, and Quantum Machines demonstrating integrations. CUDA-Q Logical is now available on GitHub, and the QUOPS reference implementation is also accessible.
