The CUDA-Q Platform for hybrid quantum-classical computers enables integration and programming of quantum processing units (QPUs), GPUs, and CPUs in one system. This repository contains the source code for all C++ and Python tools provided by the CUDA-Q toolkit, including the nvq++ compiler, the CUDA-Q runtime, as well as a selection of integrated CPU and GPU backends for rapid application development and testing.

To learn more about how to work with CUDA-Q, please take a look at the CUDA-Q Documentation. The page also contains installation instructions for officially released packages.

If you would like to install the latest iteration under development in this repository and/or add your own modifications, take a look at the latest packages deployed on the GitHub Container Registry. For more information about building CUDA-Q from source, see these instructions.
