Scalable Semiconductor Quantum Computer

There are many types of problems that would take today's most powerful supercomputers thousands of years to solve. Even with a significant increase in computing power, simulations of medicines, for example, are not feasible using conventional computers.


Quantum computing may soon be capable of solving such incredibly complex problems. The JARA Insitute for Quantum Information, QI for short, is developing a platform for a universal quantum computer based on spin qubits that is compatible with existing semiconductor technologies.

A particular technological problem, however, is the need to gain control over the coupling between qubits. Team QuTech, which consists of Professor Hendrik Bluhm, Matthias Künne, Dr. Lars Schreiber and Inga Seidler, has now developed an architectural element with which to overcome this problem. The technology is currently being patented and a spin-off company is being established.

Each year, RWTH recognizes university projects that contribute to the standing of the Aachen region as a hub of innovation. The submitted proposals are evaluated according to criteria such as technology advancement, innovation potential, customer benefit, potential for further development, commercial potential, and overall impression. In 2020, Professor Bluhm’s team was among the winners of the annual university competition.

The JARA Institute for Quantum Information, co-founded by Bluhm, is a joint initiative of RWTH and Forschungszentrum Jülich that institutionalizes the long-lasting collaboration between the two institutions in the field of Quantum Information Science.
