Dr. Simon Gerber
Group Leader "Quantum Photon Science"
5232 Villigen PSI
Simon Gerber is a tenured scientist and head of the Quantum Photon Science Group (formerly Quantum Technologies) within the Photon Science Division of the Paul Scherrer Institut (PSI). His degrees are from ETH Zurich and include a BSc in Physics , a MSc in Physics with distinction, as well as a Dr. Sc. for experimental work at the Department of Physics of ETH Zurich and the Laboratory for Neutron Scattering of PSI. During his PhD he investigated the interplay of unconventional superconductivity and magnetism in the vicinity of quantum criticality, primarily using low-temperature, high-magnetic field neutron scattering techniques. Thereafter, he moved to the Stanford Institute for Materials & Energy Sciences of the SLAC National Accelerator Laboratory and Stanford University as a postdoctoral fellow, where he focused on ultrafast and single-shot experiments of correlated electron systems at accelerator-based photon sources, namely X-ray free-electron lasers. Honours include a Fellowship of the Swiss Study Foundation, a Fellowship of the Swiss National Science Foundation, the Swiss Neutronics Young Scientist Prize of the Swiss Neutron Scattering Society, and the IBM Award in Condensed Matter Physics of the Swiss Physical Society.
Since his return to PSI as a tenure-track scientist in 2016, Simon Gerber engages in efforts to exploit PSI's accelerator-based photon sources, in particular the SwissFEL X-ray free-electron laser, to image coherent quantum control of solid-state qubit systems. Since 2019 he acts as ad interim and since 2021 as permanent head of the Quantum Photon Science Group (formerly Quantum Technologies), which includes supervision of PhD students and postdocs, as well as line management of the group's optical laboratories and the two endstations: the X01DC beamline at the SLS and SwissFEL Cristallina, where he is leading the Cristallina Quantum sub-project. The latter activity also involves the build-up of bespoke low-temperature, high-magnetic field sample environments and the development of new measurement schemes, which make use of the unique properties of SwissFEL's ultrashort X-ray pulses. He is a board member of PSI's Research Initiative Quantum Technologies Collaboration (QTC@PSI).
Simon Gerber's scientific research is focused on quantum many-body phenomena in condensed matter. It includes topics of fundamental condensed matter physics, such as the interplay of unconventional superconductivity and magnetism in quantum critical regimes, or charge order in high-temperature superconductors. In addition, he uses pulsed photon sources to study the non-equilibrium dynamics of correlated electron systems, ultrafast charge memory devices and coherent control of driven solid-state qubit host materials.
