Quantum Computing

Quantum computers have the potential to exceed the limits of conventional computing systems many times over. Medicine, logistics, material development and cryptography are just some of the fields that can experience enormous progress through quantum computers. Although there are already a variety of different approaches to quantum computing, there are currently only a few realizations in Germany that go beyond the laboratory setup.

Therefore, Fraunhofer IPMS is researching scalable technologies for semiconductor qubits together with German and European partners. For this purpose, we develop industry-oriented CMOS-compatible manufacturing methods. We deal with all important components of quantum computers, from material screening, process development and new integration concepts to characterization and implementation of necessary drive electronics. The state-of-the-art 300 mm semiconductor infrastructure of the Center Nanoelectronic Technologies offers excellent conditions for this.

Our research topics at a glance:

• Fabrication of qubits and their electronic interfacing, with special emphasis on industry-oriented scalability (Si/ SiGe, Si-MOSFET and superconducting qubit technologies).
• Development of new and optimized materials, processes and integration concepts for cryoelectronics as well as superconducting metallization concepts
• Development of manufacturing processes for nanostructuring, but also material development and electrical control from the CMOS area
