Welcome to the CUDA Quantum repository


The CUDA Quantum 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 Quantum toolkit, including the nvq++ compiler, the CUDA Quantum runtime, as well as a selection of integrated CPU and GPU backends for rapid application development and testing.
