Language Specification

NVIDIA CUDA Quantum is a programming model for heterogeneous quantum-classical computing available in C++ and Python. As such, the model provides primitive types, concepts, syntax, and semantics that enable the integration of quantum processors with existing NVIDIA multi-GPU parallel programming models and architectures.

CUDA Quantum is a library-based language extension that defines quantum code as typed callables in standard C++. These callables are meant to be compiled with standard C++ compilers and run via quantum computer simulators or physical quantum architectures. When annotated with a unique quantum function attribute, these functions can be enhanced with standard circuit optimization and transformation passes.
