Nvidia added CUDA-Q Logical to its open-source CUDA-Q platform, giving researchers and developers a toolkit for working with logical qubits and quantum error correction. On December 10, 2024, quantum hardware company Infleqtion used this technology to design and run a materials science experiment with logical qubits, achieving a measurable reduction in logical error rates. Roughly 75% of publicly available quantum processors are supported by CUDA-Q. Version 0.8 of CUDA-Q, launched in 2024, improved simulation speeds by 2.4 to 2.9 times for certain variational quantum algorithms. Nvidia is also developing NVQLink, a technology designed to enable microsecond-latency connections between quantum hardware controllers and GPUs.
