Open Superconducting Quantum Computers (OpenSuperQPlus)
Research Project, 2023 – 2026

Just like its predecessor OpenSuperQ, the OpenSuperQPlus project is part of the European Quantum Flagship Initiative. It is continuing and enhancing OpenSuperQ and brings together most of its team with new partners, resulting in a total of 28 partners from 10 countries under the leadership of Forschungszentrum Jülich.

Structured into two distinct project phases of 3.5 years each, OpenSuperQPlus follows an ambitious agenda with the ultimate goal of developing a versatile 1,000-qubit quantum-computing system made in Europe.

During the current first phase, quantum computer demonstrators with the target of controlling a 100 qubits each will be developed at three partner sites in the Netherlands, Sweden, and Germany. These systems will lay the foundation for the final 1,000-qubit system by the end of the project and are intended to be made accessible to end users in science and industry via a cloud platform.

The large-scale consortium anticipates special use cases in quantum simulation for the chemical industry and materials science, as well as in solving optimisation problems, advancing machine learning and piloting quantum error correction.
