Quantum technologies

­In superposition

Basics and applications of quantum technologies and quantum computing

There is no either-or here, quanta can take on different states – and they can do so simultaneously. Physicists call this superposition. The realm of the quantum has its own logic and this is exactly where its enormous opportunities lie. Jülich wants to take advantage of them.

Quantum technology will change our world – in science, industry, business and everyday life. However, the optimal synthesis of theoretical knowledge and practical competence is needed in order for the high expectations to be fulfilled regarding this revolutionary technology. This is a challenge that is a perfect match, as this is where Forschungszentrum Jülich can play to its particular strengths in the area of benefit-inspired fundamental research. Jülich combines fundamental research in quantum materials and quantum computing with concrete application development.

The research campus is intended to cover the entire development chain: from concepts and novel components to the quantum computer prototype, all key components will be developed at the Helmholtz Quantum Center (HQC), while the Jülich Supercomputing Center (JSC) will make a range of systems of different maturity levels available to a broad user community via the Jülich User Infrastructure for Quantum Computing (JUNIQ). At the same time, the JSC will work on the realisation of quantum algorithms and their application. It is therefore no coincidence that, as part of the EU research initiative Quantum Flagship, the first European quantum computer is being built at Jülich. With its scientists and unique infrastructure, Forschungszentrum Jülich offers the best conditions.


 How does a quantum computer work?

Quantum computers do not work like conventional computers. The latter use bits, in other words, zeros and ones. Die grundlegenden Einheiten eines Quantencomputers sind dagegen Quanten-Bits, sogenannte Qubits. The basic units of a quantum computer, on the other hand, are quantum bits, so-called qubits. They cannot only assume the value one or zero – but both at the same time. More...


David DiVincenzo

Prof. David DiVincenzo

Prof. David DiVincenzo is considered a pioneer in the field of quantum information. Among other things, his name is associated with the development of criteria that a quantum computer must meet, known as the “DiVincenzo criteria”. The physicist is head of the Theoretical Nanoelectronics division at the Peter Grünberg Institute (PGI-2) and teaches at RWTH Aachen University’s JARA Institute for Quantum Information.

Tommaso Calarco

Prof. Tommaso Calarco

Prof. Tomasso Calarco is a two-time Marie Curie and Fulbright Fellow and a member of the Executive Committee of the European Academy of Sciences. He is one of the intellectual fathers of the Quantum Manifesto, which called for a European initiative for next generation quantum technologies in 2016. The scientist is head of the Quantum Control division at the Peter Grünberg Institute of Forschungszentrum Jülich (PGI-8).

Kristel Michielsen

Prof. Kristel Michielsen

Prof. Kristel Michielsen heads the Quantum Information Processing group at the Jülich Supercomputing Centre (JSC) and co-authored the publication in “Nature” on Google’s proof of quantum superiority. She works on models and methods with which complex quantum systems can be simulated using supercomputers. She thus plays a major role in the development of various types of quantum computers and their promising special applications.

Hendrik Bluhm

Prof. Hendrik Bluhm

Prof. Hendrik Bluhm did research at the American elite universities of Stanford and Harvard. He is an expert on spin qubits. The Alfried Krupp Prize for Young University Teachers laureate heads the JARA-Institute for Quantum Information (PGI-11) together with Prof. DiVincenzo.

Wilhelm Mauch

Prof. Frank Wilhelm-Mauch

Prof. Frank Wilhelm-Mauch coordinates the OpenSuperQ project of the European Quantum Initiative, which aims to build the first European quantum computer at Forschungszentrum Jülich. The physicist heads the "Quantum Computing Analytics" division at the Peter Grünberg Institute (PGI-12) and has received a Google Resesarch Award and the APS Outstanding Referee Award from the American Physical Society (APS), among other awards, for his work.

Initiatives, infrastructure and cooperation

EU Flagship

Quantum Flagship

The Quantum Flagship is one of the most ambitious long-term research and innovation initiatives of the European Commission. The large-scale initiative, which will be financed with € 1 billion over a period of 10 years, started in October 2018. Forschungszentrum Jülich contributes its expertise to three projects.

Quantum Center

Helmholtz Quantum Center

With the Helmholtz Quantum Center (HQC), a central technology laboratory is being established which covers the entire research spectrum for quantum computing – from research into quantum materials to prototype development. The HQC brings together six research fields and seven technology clusters, thus combining basic research, theory and development – all the way from quantum materials to complete quantum computer systems.


JARA-Institut für Quantum Information

The JARA Institute for Quantum Information combines theoretical and experimental research in quantum information science with the goal of achieving decisive progress in the realisation of quantum computations on a large scale. The institute is a joint initiative of RWTH Aachen University and Forschungszentrum Jülich.

JUNIQ - A unique user infrastructure for quantum computing

JUNIQ, short for Jülich User Infrastructure for Quantum Computing, will be the unified portal to a number of different quantum computers – accessible via the cloud for German and European users. More...
