Joining forces for a European quantum computer

Ten international partners from academia and industry will collaborate in a unique research endeavour to build a high-performance quantum computer, available to a broad community of users. The project, OpenSuperQ, coordinated by Saarland University in Germany, is part of the EU’s unprecedented €1 billion Flagship initiative on Quantum Technology.
Chalmers University of Technology, Sweden, contributes with in-depth knowledge of the primal building blocks of the quantum computer.

The world is currently taking the first steps into the second quantum revolution where quantum technologies will play a decisiv​e part in advanced technology. In the last few years, quantum computing has been elevated from a basic research concept towards a viable cloud offering which will be affecting people’s everyday lives in multiple ways.

In order to catalyse the transfer of quantum computing research from the lab to the market, the collaborative project OpenSuperQ​ (An Open Superconducting Quantum Computer) aims at developing a large quantum computing system, available to external users. The open approach allows the system to serve a large community of early adopters and educate the next generation of quantum scientists, developers, and users.

“Building a quantum computer with 100 qubits is a very ambitious and difficult task. By joining forces in Europe and contributing with our respective expertise, the task will be easier to solve,” said Jonas Bylander, associate professor at the Quantum Technology Laboratory at Chalmers University of Technology and one of the principal investigators in OpenSuperQ.

Chalmers has over the years made many contributions to developing the field, coordinated several EU projects through professor Göran Wendin, and is leading the Wallenberg Centre for Quantum Technology​​​, the major Swedish effort of engineering a quantum computer.

“We are fortunate to have gathered a team of the most renowned players in the field bringing together science, engineering and application development at the highest level,” says Professor Frank Wilhelm-Mauch from the Physics Department of Saarland University who coordinates the project.

In order to fuel the translation of technologies into applications, the OpenSuperQ system will be located at the supercomputer centre at Forschungszentrum Jülich in Germany. The hardware will be based on superconducting integrated circuits and contain the necessary technological infrastructure, including a control system and cryogenics. The software stack will be integrated, from user access all the way to low-level control. 

While designed as an all-purpose quantum computer, the project particularly targets applications for quantum simulation in chemistry and materials science as well as for optimisation and machine learning. The computer will be among the leading platforms in the world and the first of its kind developed in Europe.

To maximise the project’s impact in the field, the partners strive to establish close links with European and international research and industry players, both as technology partners and as users. The involvement of highly recognised stakeholders in the advisory board, the basic science group and a user board will further contribute to the achievement of this aim.

OpenSuperQ receives funding from the current EU Research Framework Programme Horizon 2020 and will run for an initial period of three years. For more information, please visit​

>>About the Quantum Flagship

The Quantum Flagship was launched in 2018 as one of the largest and most ambitious research initiatives of the European Union. With a budget of €1 billion and a duration of 10 years, the flagship brings together research institutions, academia, industry, enterprises, and policy makers, in a joint and collaborative initiative on an unprecedented scale. The main objective of the Flagship is to consolidate and expand European scientific leadership and excellence in this research area as well as to transfer quantum physics research from the lab to the market by means of commercial applications and disruptive technologies. With over 5,000 researchers from academia and industry involved in this initiative throughout its lifetime, it aims to create the next generation of disruptive technologies that will impact Europe’s society, placing the region as a worldwide knowledge-based industry and technological leader in this field.
