I completed my BSc in Physics at the University of Patras in Greece. After a one year research stay at NCSR Demokritos in Athens, I went to the Max Planck Institute for Solid State Research to do my PhD thesis in the group of Klaus Kern. In 2006 I moved to the group of Silvano De Franceschi at CEA Grenoble for my postdoctoral studies. Since 2016, and after group leader positions at IFW Dresden and JKU Linz, I am the PI of the Nanoelectronics group at IST Austria.
Postdocs
Kevin Roux
kevin.roux@ist.ac.at
I completed my MSc in Physics at Université Paris Saclay and Institut d’Optique with a specialization in quantum physics; optics and condensed matter. After my master thesis at ETHZ in the group of Tilman Esslinger I started my PhD at EPFL under the supervision of Pr. J-P. Brantut where I build the first experiment combining strongly interacting fermions and photons in the strong coupling regime. Since Nov 2022 I work in the nanoelectronics group on cQED with holes in gate-defined quantum dots with the goal to use this system to simulate the physics of strongly correlated fermions with long-range photon mediated interactions.
Simon Robson
simon.robson@ist.ac.at
I completed my BSc in 2015, majoring in Physics and Computer Science at the University of Auckland in New Zealand. Afterwards, I moved to the University of Melbourne and obtained my MSc in 2017 with a thesis on the deterministic implantation of single phosphorus ions into silicon. I then stayed on for my PhD and extended these studies to develop a method to create entangled donor nanoarrays in silicon for a flip-flop qubit architecture, along with investigating semiconductor device failure analysis using a near-surface focused ion probe. I joined the Nanoelectronics group in July 2023 with the goal to create large-scale quantum devices based on hole qubits in Ge/SiGe heterostructures.
PhD Students
Marián Janík
marian.janik@ist.ac.at
I received my Bachelor degree in Electrical engineering (2015) and my Master of Engineering degree in Nuclear and physical engineering (2018) from Slovak University of Technology and my Master of Science degree in Solid state physics (2017) from Comenius University in Bratislava. In my theses I studied the structure of thin films using X-ray diffraction. I joined the group in June 2019 and I aim to couple two distant hole spins with a photon.
Carla Borja Espinosa
carlanataly.borjaespinosa@ist.ac.at
I completed my BSc in Physics (2020) at Yachay Tech University in Ecuador. During my bachelor’s, I did a one-month internship at the University of Alicante in Spain where I learn about the Scanning Tunneling Microscope in the break-junction configuration for measuring single-molecule conductance. In September 2021 I completed my MSc degree from the Barcelona Institute of Science and Technology. Here, I focused on the structural characterization of Ge-based heterostructures by means of Transmission Electron Microscopy. Since January 2022 I am part of the Nanoelectronics group, first as a scientific intern and then as a student to work on spin qubit experiments.
Jaime Saez-Mollejo
jaime.saezmollejo@ist.ac.at
I completed my BSc in Physics and MSc in Condensed Matter Physics at Universidad Autónoma de Madrid and during my experimental master thesis I studied superconducting proximity effects in single quantum dots in InAs nanowires. I joined the Nanoelectronics group in June 2020 as a PhD student for working in coupling hole spin qubits in Ge .
Oliver Sagi
oliver.sagi@ist.ac.at
I obtained my Bachelor and Master degree at the Budapest University of Technology and Economics, in Hungary, where I dealt with Electron Spin Resonance (ESR) and microwave impedance measurements. In September 2019, I joined the PhD program of IST Austria. In April 2020, I affiliated the Nanoelectronics group where my research focuses on hybrid Ge quantum circuits.
Yona Schell
yona.schell@ist.ac.at
I completed my bachelor in physics at University of Strasbourg in 2019. I obtained my master in nanophysics at University Grenoble Alpes and my master in physical engineering for photonics and microelectronics at Phelma in 2021. I joined the group in February 2021 as an intern for my master thesis on quantum devices in Ge quantum well. I started the PhD program in September 2021 where I am working on hole spin qubits.
Maksim Borovkov
maksim.borovkov@ist.ac.at
I obtained my Bachelor of Science degree from the Moscow Institute of Physics and Technology in the summer of 2020 and a Master of Science degree from Princeton University in the winter of 2022. As an undergraduate student, I was an intern at the Nanoelectronics group at ISTA participating in both the Germanium qubit and the hybrid InAs/Al nanowires projects. Supervised by Prof. Bernevig at Princeton, I theoretically studied the Topological Heavy-Fermion model applied to the Twisted Bilayer Graphene. Now, returning back to ISTA as a graduate student, I am excited to explore the physics and technological prospects of hybrid semiconductor-superconductor structures based on Germanium, including but not limited by minimal Kitaev chains and Andreev qubits, with the ultimate dream of creating a topological qubit.
Giorgio Fabris
giorgio.fabris@ista.ac.at
I obtained my Bachelor’s degree in Physics Engineering from Politecnico di Milano and I completed my Master’s degree in Quantum Engineering at ETH Zurich in May 2023.
I conducted my Master thesis at the University of Basel, where I focused on novel qubit platforms based on proximitized InAs 2DEGs within cQED architectures. I joined the Nanoelectronics group in September 2023 as a PhD student for working on spin qubits and hybrid semiconductor-superconductor devices based on Ge.
