Fujitsu Open-Sources Quantum Software Package With 100+ Components
Fujitsu has released its Open Quantum Application Research Package (OpenQARP) globally as open-source software, making more than 100 quantum software components available to researchers and developers. The package includes Fujitsu-developed quantum algorithms and can run across environments ranging from standard PCs to Fujitsu’s quantum simulator and NVIDIA’s CUDA-Q platform.
The release is aimed at reducing the amount of software development required to build and test quantum applications. Fujitsu says the package had already been provided in beta to more than 80 organisations through joint research and its Quantum Simulator Challenge before the public release.
More Than 100 Components for Quantum Development
OpenQARP contains more than 70 reusable building blocks covering tasks such as quantum-state preparation, ansatz layers and the Quantum Fourier Transform. It also includes more than 20 ready-to-run algorithms, allowing developers to combine existing components rather than implement complete quantum routines from scratch.
Fujitsu says the approach can substantially reduce coding work. In one quantum-chemistry research example, an implementation using the ADAPT-VQE algorithm was reduced from about 130 lines of Python code to fewer than 40 lines using OpenQARP components.
Supports Fujitsu and NVIDIA Environments
The software is designed to work across different computing environments. Developers can install it on a standard Python-compatible PC, while integration with NVIDIA CUDA-Q provides a route to GPU-accelerated hybrid quantum-classical computing.
OpenQARP can also run on Fujitsu’s 40-qubit state-vector quantum simulator, which is built on a large-scale high-performance computing environment using 1,024 PRIMEHPC FX700 systems equipped with Fujitsu’s A64FX processors.
Fujitsu Algorithms Included
The package includes quantum algorithms developed by Fujitsu for specific research applications. Among them are methods designed to reduce quantum circuit depth in quantum-chemistry calculations and another approach aimed at simplifying input-state preparation for quantum phase estimation.
The software can therefore be used for work spanning areas such as quantum chemistry and other computationally intensive research fields. Fujitsu's broader objective is to make reusable quantum algorithms more accessible rather than having researchers repeatedly develop application-specific implementations.
Open Source Push Targets Wider Adoption
OpenQARP version 0.1.0 is being released under the Apache License 2.0. Fujitsu plans to continue expanding the package and its supported environments as it works to bring quantum application development beyond specialist research teams.
The public release gives developers access to Fujitsu's software components without requiring access to the company's proprietary development environment. With more than 80 organisations already involved during the beta phase, Fujitsu is now opening the project to a broader quantum-computing community.
