+45 2116 2657

HCØ Building 3-406

My activities explore practical quantum design and cryogenic electric manipulation and readout techniques. By choosing the material, geometry and boundary conditions, we create nanodevices with well-controlled, often surprising spin-electronic properties.

Low-dimensional semiconductors such as nanowires and 2D electron gases challenge us to harness the role of spin-orbit coupling, type of confinement, and the interplay between conduction band, valence bands, and superconductivity. Interested? Come join us! For my CV in a nutshell, read on.

I am Professor in Experimental Condensed Matter Physics at the Niels Bohr Institute (NBI). Pioneering spin-orbit coupling in nanostructures, I obtained my PhD at Cornell University under guidance of Prof. Daniel C. Ralph in 2007. After postdoctoral research with Prof. Charles Marcus in Boston I served as Research Associate at Harvard University before I moved to University of Copenhagen to help build the Center for Quantum Devices, an excellence center established 2012-2023 by the National Danish Research Foundation. In 2016 I founded QDevil, a quantum electronics hardware company located in Copenhagen. As CTO, I leveraged support through the European Innovation Council (EiC) and the Innovation Fund Denmark (IFD) to mature the quickly growing company into an internationally trusted partner for quantum technology research labs around the world, both academic and industrial. My innovative approach to research and education at the intersection of fundamental condensed matter physics and applied quantum technologies was recognized in 2019 by the university’s SCIENCE business award. I also serve as Principal Scientist at Quantum Machines, which QDevil joined in 2022, becoming one of the largest high-tech companies that is entirely focused on quantum control. At the Niels Bohr Institute, I lead a research group on semiconducting and superconducting quantum devices, including quantum dots, spin qubits, superconducting resonators and encoded qubits. Since the foundation of the Center for Quantum Devices in 2012, I have steadily advanced the cutting edge of NBI’s research and educational capabilities, specifically in the areas of condensed matter quantum transport measurements and the development of solid-state qubits. My innovative low-temperature techniques have advanced quantum science around the world, recognized by the 2024 Technology Transfer Prize of the German Physical Society. My overarching goal is to understand and proliferate the interplay of semiconductors and superconductivity in low-dimensional systems, and harness the resulting spin-electronic properties for quantum information applications.
