Fujitsu Releases Open Quantum Application Research Package as Open Source

Insider BriefPRESS RELEASE — Fujitsu Limited today announced the global open-source release of its quantum application development software, Open Quantum Application Research Package (OpenQARP (code name)).The software offers over 100 software components, including Fujitsu-developed quantum algorithms. These components can be combined to significantly streamline quantum application development. The software is compatible with various execution environments, such as Fujitsu’s quantum simulator built on a large-scale HPC environment and the NVIDIA CUDA-Q platform [1] for hybrid quantum-classical computing. Prior to its public release, Fujitsu has provided a beta version of the software to over 80 organizations since February 2026 through joint research and the Quantum Simulator Challenge [2], and it has already been used to generate numerous research and development results in quantum applications.By publicly releasing the software, which includes Fujitsu-developed algorithms, as open-source software, Fujitsu aims to accelerate the practical adoption of quantum software and contribute to addressing societal challenges through quantum technology.Quantum computing is expected to provide one approach to solving complex problems that conventional computers cannot address in various societal domains, such as materials development, financial optimization, healthcare, and drug discovery. Fujitsu has been engaged in the development of specific quantum applications through joint demonstrations with customers across various industries and joint research with universities and research institutions. To accelerate the practical adoption of quantum technology, it is crucial that cutting-edge algorithms are widely reusable rather than being custom-built for specific problems. Therefore, Fujitsu developed Open Quantum Application Research Package (OpenQARP (code name)), a quantum application development software that implements versatile quantum algorithms as components to promote their use in quantum algorithm development across various industries. To further expand the adoption of quantum technology, Fujitsu is now publicly releasing the software as open-source software on GitHub.Fujitsu will continue to promote OpenQARP (code name) not only within the quantum community but also across various industrial sectors. The company aims to accelerate the development of a wide range of quantum applications in society and contribute to addressing societal challenges through quantum technology.Providing the open tools and resources to accelerate quantum application development is one of the most important ways to accelerate the journey to useful quantum computing. Fujitsu’s use of CUDA-Q in OpenQARP (code name) shows how the right open tools, with access to GPU-acceleration, are empowering developers to build and scale toward quantum utility.All product names and other proper nouns mentioned herein are trademarks or registered trademarks of their respective owners.OpenQARP (code name) ― featured pageNVIDIA CUDA-Q platformAbout the Fujitsu Quantum Simulator Challenge 2025-26 (Technology Topics, December 17, 2025)A Simple Method for Seniority-Zero Quantum State PreparationSpectral subspace extraction via incoherent quantum phase estimationA Hybrid Quantum Computing Method for UV–Vis Spectroscopy of Solvated Molecules at Room TemperatureTopicsShare Get the latest research, company news, and market intelligence every week.
