Explore a range of software and platforms available today to help you get started with quantum computing.
Quantum-inspired technology — Digital Annealer

Digital Annealer is a computing technology inspired by quantum phenomena that uses annealing-based algorithms to solve combinatorial optimization problems quickly. As a software-based solution, Digital Annealer can be deployed quickly in customer environments.
Commercial quantum computers

Fujitsu's superconducting quantum computer has been deployed at the National Institute of Advanced Industrial Science and Technology (AIST). The system is designed to be scalable to several hundred qubits. Contact us to discuss quantum computer deployment or joint research.
OpenQARP

OpenQARP (Quantum Application for Research Package) has been available as open-source software since September 2026. By bringing together more than 100 software components, including quantum algorithms developed by Fujitsu, OpenQARP helps streamline quantum application development.
Qulacs (quantum circuit simulator software)

Qulacs is open-source quantum circuit simulator software designed to simulate quantum circuits at high speed.
It was developed by Osaka University, QunaSys, NTT, and Fujitsu.
Open Quantum Toolchain for Operators and Users

Open Quantum Toolchain for Operators and Users (OQTOPUS) is a suite of core software covering everything from environment setup to operation. It is provided as open-source software and can be freely customized to meet users' needs.
Custom quantum computing environment development

We design and build customized quantum computing environments by integrating quantum simulator execution environments, external libraries, and other components to meet specific customer requirements.
