cuQuantum SDK: A High-Performance Library for Accelerating Quantum Science

Welcome to the cuQuantum SDK documentation!

NVIDIA cuQuantum SDK is a high-performance library for quantum information science and beyond. Currently its primary target is quantum circuit simulations and it consists of two major components:

  • cuStateVec: a high-performance library for state vector computations

  • cuTensorNet: a high-performance library for tensor network computations

In addition to C APIs, cuQuantum also provides Python APIs via cuQuantum Python.

NVIDIA cuQuantum Appliance offers a containerized solution, including a distributed state vector simulator backend for IBM’s Qiskit Aer and a multi-GPU backend for Google’s qsim state vector simulator.

To quickly get started with cuQuantum or cuQuantum Python installation, please refer to our guide on Getting Started for instructions.
