Projects and Collaborations
PGI-9 is currently involved in multiple projects and collaborations listed below:
QuantERA - MAGMA project
This Summer, the MAGMA project of the European QuantERA programme for Research and Innovation in Quantum Technologies has officially started. In this project, theory, modeling, fabrication, and experiment will be combined to study the interplay between magnetism and superconductivity in state-of-the-art nano-electronic devices based on magnetic topological materials. This hybrid system has properties that are very promising for realizing robust topological states that can serve as future building blocks for quantum computation.
Development of spin-qubit devices from ZnSe/(Zn,Mg)Se quantum structures
DFG project together with Prof. Dr. Lars Schreiber (Lars Schreiber - RWTH AACHEN UNIVERSITY Institut für Quanteninformation - (rwth-aachen.de) from RWTH on electrostatically-defined spin qubits from II-V.
ForMikro - SiGeSn-NanoFETs (BMBF)
Research-intensive microelectronics and its applications are drivers of progress, competition and innovation across industries. To keep the pipeline of new microelectronics full, new knowledge in the natural and engineering sciences is to be tapped for future microelectronics. Funding for universities and non-university research institutions focuses on topics that are not yet being researched industrially, but for which there is proven interest from industry. The bridge between basic research and industry-led research in microelectronics is thus being expanded.

ML4Q stands for Matter and Light for Quantum Computing. The Cluster of Excellence started its scientific program in 2019 to lay the foundations for a comprehensive quantum technology with computing and networking capabilities. Top scientists from the fields of solid-state physics, quantum optics and quantum information are collaborating on this project.

Quantum information technology promises an enormous increase in computing power. A quantum information processor (QIP) requires a very high number of coupled qubits which must be operated at extremely low temperatures. For control, readout and coupling of such qubits, a control unit consisting of classical circuits is also needed. In order to scale down the quantum computer, the control units must be located in close proximity to the qubits when the number of qubits is high, and operated at extremely low operating voltages to minimize the power dissipation. This, however, is not possible with conventional CMOS technology. In this project, a CMOS technology dedicated for operation at cryogenic temperatures is to be developed based on advanced silicon technology.

Partners: RWTH Aachen, IHP Frankfurt Oder, University of Stuttgart.
Quantum technologies are technologies based on the targeted exploitation of quantum effects. Examples are semiconductor technologies, magnetic resonance imaging or lasers. Current developments in the second generation of quantum technologies focus on the controlled quantum state of individual or coupled systems themselves. This opens up possibilities for new applications in information transmission and processing, highly precise and sensitive measurement and imaging methods, or overcoming current limitations in the simulation of complex systems.
The project is part of the Bavarian State Government's technology offensive Hightech Agenda Bavaria and serves the goal of coordinating and expanding the research work of the two locations Julius-Maximilians-Universität Würzburg and Forschungszentrum Jülich on building blocks for quantum computing based on topological materials, conducting joint research with experimental and theoretical approaches, and supporting the promotion of young researchers in the field of topological quantum computing.
Superconducting qubits are currently among the leading quantum hardware platforms. In order to further extend the technological lead and establish superconducting qubits as a frontrunner in and after the NISQ era, it is necessary to achieve error rates that are significantly lower than before. To this end, a Thermal Laser Epitaxy (TLE) is being commissioned. This is a coating process that enables patterned layers of a wide variety of material combinations in a vacuum. This should make more powerful superconducting quantum electronics possible.
In this project, a quantum computer demonstrator with processor generations of different performance profiles (size, precision, application reference) based on superconducting circuits will be created. The core element is the combination of a qubit double strand with resonators. The circuits achieve their high quality through precise fabrication and analytics coupled with detailed modeling. System integration is guided by a tightly tuned software and firmware stack. A supply chain of supporting technologies is being established in preparation for further scaling steps.
In this collaborative project, the world's first millikelvin and UHV scanning probe microscopy instrument family based on adiabatic demagnetization cooling is being developed. This is versatile as an experimental environment for the emerging research field of quantum nanoscience and quantum technologies.
