Current team

Thomas Botzung (Post-doc): After obtaining his PhD degree in 2019 (University of Strasbourg and University of Bologna), from 2020 until 2022 Thomas worked as a post-doc in the theoretical quantum technology group at RWTH Aachen, Germany. He continued his research in the Laboratoire de Physique de Modélisation des Milieux Condensés in Grenoble, France, performing numerical studies in SU(N) spin lattice systems. Since May 2024, he joint us back in Strasbourg to work on the project DINPOPARC (“Disorder-Induced Non-Classical States in Polaritonic Chemistry”).


Ruben Daraban (PhD student): After obtaining his Master's degree in physics at the University of Strasbourg in 2023, Ruben continued his studies with a PhD project afterwards. His research focuses on studying entanglement buildup in quantum circuits using classical simulations based on tensor network methods.


Tam'Si Ley (PhD student): Tam'Si obtained a master degree from Télécom SudParis and works as a Quantum Scientist for the Parisian quantum software startup QuantFi. In the framework of an interdisciplinary CIFRE project he is pursuing his computer science PhD degree at the University of Strasbourg, working on "Resource estimation for practical quantum computing".


Luiz Otavio Ribeiro Solak (Visiting PhD): Obtained his Master’s Degree in Sciences at the State University of Ponta Grossa (UEPG) in 2021 (supervisor: Lucas Stori de Lara). Then he proceeded to work on his PhD with Celso Jorge Villas-Bôas at Federal university of São Carlos (UFSCar) focusing on Quantum Information processing in Atom-Cavity systems. He is visiting from Sep. 2024 to July 2025.


Pedro Pablo Rosario Vargas (Visiting PhD): After obtaining his bachelor degree in 2021 (Colombia), Pedro moved to São Carlos - Brazil, where he continued his PhD studies on multipartite entanglement witnesses using collective operators, under the supervision of Prof. Romain Bachelard. He is visiting from Sep. 2024 to August 2025.

Former members

Guillermo Preisser (PhD student): Guillermo studied physics a the National Autonomous University of Mexico in Mexico City and graduated in 2019. For his PhD studies he moved to Strasbourg in February 2020. He is worked on the QUSTEC PhD project on "Semi-classical modelling of open quantum technology platforms", and explored new types of MPS/tensor network codes for analyzing entanglement dynamics in quantum many-body systems. He now works for Quantinuum in London.


David Wellnitz (PhD student): From 2013 to 2018, David studied physics at the University of Heidelberg. In 2018, he graduated (group of M. Weidemüller) on the application of network theory to atomic spectra. For his PhD studies he moved to Strasbourg in Nov. 2018. He was working on the LabEx NIE project: "Novel approaches to quantum many-body dynamics in molecular complexes", and exploring collective dynamics in collective light matter coupled-systems. He is now a post-doc at JILA in Boulder, CO, US.


Stefan Schütz (post-doc): Stefan obtained his PhD degree in physics at the Saarland University in Saarbrücken, Germany. In Strasbourg, from Oct. 2017 - Dec. 2018 he was working on the IdEx Attractivité project "Simulation of transport in engineered many-body quantum systems" (STEMQuS). He laid important foundations for exploring cavity-coupled many-body dynamics by applying adiabatic elimination theories.


Tiago Santiago do Espirito Santo (visiting PhD): Tiago studied Physics at the Universidade Federal de São Carlos (UFSCar) in Brazil and received his PhD degree in 2020 (under the supervision of R. Bachelard, romain.df.ufscar.br). He was visiting our team from Sep. 2017 – Mar. 2018 and worked on numerical modeling of cold atom light-scattering experiments.
