Fujitsu Limited today revealed the international open-source release of its quantum application advancement software application, Open Quantum Application Research Package (OpenQARP (code word)).
The software application provides over 100 software application parts, consisting of Fujitsu-developed quantum algorithms. These parts can be integrated to substantially improve quantum application advancement. The software application works with different execution environments, such as Fujitsu’s quantum simulator developed on a massive HPC environment and the NVIDIA CUDA-Q platform [1] for hybrid quantum-classical computing. Prior to its public release, Fujitsu has actually offered a beta variation of the software application to over 80 companies given that February 2026 through joint research study and the Quantum Simulator Challenge [2]and it has actually currently been utilized to produce various research study and advancement lead to quantum applications.
By openly launching the software application, that includes Fujitsu-developed algorithms, as open-source software application, Fujitsu intends to speed up the useful adoption of quantum software application and add to attending to social obstacles through quantum innovation.
Background
Quantum computing is anticipated to supply one technique to resolving complicated issues that traditional computer systems can not resolve in numerous social domains, such as products advancement, monetary optimization, health care, and drug discovery. Fujitsu has actually been participated in the advancement of particular quantum applications through joint presentations with consumers throughout numerous markets and joint research study with universities and research study organizations. To speed up the useful adoption of quantum innovation, it is important that advanced algorithms are extensively multiple-use instead of being customized for particular issues. Fujitsu established Open Quantum Application Research Package (OpenQARP (code name)), a quantum application advancement software application that executes flexible quantum algorithms as elements to promote their usage in quantum algorithm advancement throughout numerous markets. To even more broaden the adoption of quantum innovation, Fujitsu is now openly launching the software application as open-source software application on GitHub.
Functions of Open Quantum Application Research Package
1. Structured execution through the arrangement of flexible software application elements
OpenQARP (code word) supplies over 70 composable foundation, from state preparation and ansatz layers to the Quantum Fourier Transform. It likewise supplies over 20 ready-to-run algorithms constructed from these blocks, consisting of Subspace-Search Variational Quantum Eigensolver [3] for Noisy Intermediate-Scale Quantum [4] gadgets and quantum stage evaluation for fault-tolerant quantum computing [5]Users can integrate these elements according to their goals to establish quantum applications, thus minimizing software application efforts.Fujitsu actively utilizes the software application in its own research study and releases the resulting results. In the research study and advancement of quantum chemistry applications for determining molecular electronic states, executing a procedure utilizing the ADAPT-VQE algorithm needed around 130 lines of Python code, which its elements decreased to under 40 lines. This substantially minimizes the concern of carrying out quantum algorithms, permitting scientists to concentrate on confirming algorithms and applications.
2. Effective quantum calculation through Fujitsu-developed sophisticated algorithms
OpenQARP (code word) likewise offers Fujitsu-developed quantum algorithms as parts. These consist of the Unitary set Coupled Cluster Doubles algorithm, which leverages pre-computation arise from classical computer systems to decrease the variety of quantum gate layers (circuit depth) needed for preliminary state preparation in quantum chemical computations, and Density of States Quantum Phase Estimation, which decreases the problem of preparing intricate input states needed for quantum stage estimate and effectively acquires details about energy spectra.
3. Compatibility with different execution environments, from basic PCs to GPU-equipped systems and supercomputers
OpenQARP (code word) can be quickly set up and utilized by anybody in a basic PC environment that supports Python. It can likewise incorporate with NVIDIA CUDA-Q as a backend by means of a source develop, allowing quantum circuit execution in open GPU-accelerated environments. It can be utilized in Fujitsu’s 40-qubit state-vector quantum simulator environment, which is made up of 1,024 FUJITSU Supercomputer PRIMEHPC FX700 systems, each geared up with Fujitsu’s “A64FX” [6] processor. This supercomputing environment has actually been offered to more than 80 companies through the Quantum Simulator Challenge, and the pre-released beta variation of the software application has actually been utilized to carry out a range of quantum calculations. Fujitsu likewise prepares to sequentially support simulation environments based upon the STAR architecture for quantum computing that it is investigating.
Future Plans
Fujitsu will continue to promote OpenQARP (code word) not just within the quantum neighborhood however likewise throughout different commercial sectors. The business intends to speed up the advancement of a wide variety of quantum applications in society and add to attending to social obstacles through quantum innovation.
Remark from Sam Stanwyck, Director of Quantum Product at NVIDIA:
Offering the open tools and resources to speed up quantum application advancement is among the most crucial methods to speed up the journey to beneficial quantum computing. Fujitsu’s usage of CUDA-Q in OpenQARP (code word) demonstrates how the right open tools, with access to GPU-acceleration, are empowering designers to construct and scale towards quantum energy.
