Bahadir Dönmez, Software/System Engineer

After earning my dual bachelor's degrees in Electrical & Electronics Engineering and Physics from Bogazici University, Türkiye, I pursued a master's in Quantum Engineering at ETH Zurich. During my studies, I participated in multiple internships in the QUDEV group, focusing on superconducting quantum devices, and dedicated my master's thesis to developing a signal generation system for quantum gas experiments within the Quantum Optics group. My experience also includes an internship at Zurich Instruments, where I sharpened my Python software development skills for quantum experiment control.

As an Embedded System Engineer in the TIQI group, I combine my knowledge and skills in embedded systems, quantum technologies, and software development to design and optimize control hardware and software for state-of-the-art quantum experiment setups.

Jeremy Flannery, Post-doctoral Research Assistant

After completing my undergraduate BSc degree in physics at the University of Western Ontario (UWO), I earned my MSc at the University of Waterloo (UW) researching polymer physics using Raman spectroscopic techniques in the group of Prof. James Forrest. I then decided to focus my research on quantum information by earning my PhD at the Institute for Quantum Computing (IQC) at UW in the group of Prof. Michal Bajcsy studying enhanced light-matter interactions with ultra-cold atomic clouds. I joined the TIQI group as a postdoc working towards using quantum error correcting techniques on trapped ions.

Pavel Hrmo, Post-doctoral Research Assistant

Following my undergraduate studies in Physics at the University of Edinburgh, I attended the Centre for Doctoral Training in Controlled Quantum Dynamics at Imperial College London to obtain my MRes. I stayed at Imperial to pursue a PhD, investigating the potential application of Penning traps to quantum information processing. Afterwards, I moved to the Ion trapping group at the University of Innsbruck to do postdoctoral research on scalable quantum information processing in surface Paul traps. I joined TIQI to combine my research interests and implement a surface Penning trap capable of trapping arrays of ions.

Stephan Welte, Post-doctoral Research Assistant

I studied physics at the University of Freiburg where I wrote my master thesis in the group of Hanspeter Helm. Afterwards, I moved to Munich to do my PhD in the group of Gerhard Rempe at the Max-Planck-Institute of Quantum Optics (MPQ). In Munich, I worked with single atoms trapped in optical cavities and used this platform for applications in quantum communication and quantum computation in a network structure. After my PhD, I stayed for a postdoc at MPQ before joining the TIQI group in 2022. At TIQI, I am working on the implementation of novel schemes for quantum information processing with qubits encoded in the motional states of single ions.

Diana Prado Lopes Aude Craik, Post-doctoral Research Assistant

I'm a Marie Skłodowska-Curie (MSCA) Fellow in physics working on isotope-shift (IS) spectroscopy of trapped ions to search for new physics. During the outgoing phase of my fellowship, I worked with the Vuletić group at MIT on IS spectroscopy of ytterbium ions. At the TIQI group, I will work on precision spectroscopy of calcium ions. I completed my undergraduate studies in physics at MIT and my DPhil at the University of Oxford. Most of my research so far has been in precision measurement and quantum computing with trapped ions, but I have also had the opportunity to work with nitrogen vacancy centers in diamond at Harvard, with Ron Walsworth and Evelyn Hu.

Claudia Politi, Post-doctoral Research Assistant

I started my studies in Physics at the Second University of Naples (Italy), where I first became interested in atomic physics. I completed my bachelor's thesis in the group of Prof. Livio Gianfrani on Doppler broadening thermometry. For my master's studies, I moved to the University of Pisa (Italy). There, I became fascinated by laser cooling and trapping of atoms, as well as degenerate quantum gases. This interest led me to join the group of Prof. Francesca Ferlaino in Innsbruck (Austria) as an external master's student. At the end of 2017, I obtained my master's degree and shortly after started as a PhD student in the same research group, focusing on many-body quantum phases of dipolar erbium and dysprosium atoms. In June 2023, I joined the TIQI group as a postdoc, working on quantum information with circular Rydberg states.

Tanja Behrle, PhD Student

For my Bachelor's thesis I studied ultracold atoms in the Synthetic Quantum Systems group and later on as a research assistant in the Ultracold Quantum Gases group at the University of Heidelberg. During my graduate studies I got curious about quantum computing and decided to explore the field with a Master’s thesis in the Superconducting Quantum Devices group at the University of Oxford. Today for my PhD I am keen to continue working on quantum information combining it with quantum optics in the Trapped Ion Quantum Information group at ETH Zurich.

Francesco Lancellotti,  PhD Student

I studied physics and electrical engineering as an undergraduate at Polytechnic of Turin. Then I followed a theoretical master course in Physics in a consortium of universities located in Turin, Triest and Paris, receiving an Italian-French double degree. Here I found myself interest in Quantum Information. For this reason, I worked on Quantum Cryptography for my master project with the Nonlinear Photonics Group at INRS in Montréal (Canada). Then, appreciating the outstanding work of the Trapped Ion Quantum Information group at ETH Zurich, I joined it for my PhD.

Brennan MacDonald-de Neeve, PhD Student

During my Bachelor in engineering at McGill University, my lectures in thermodynamics and fluid mechanics got me interested in related topics in physics like statistical mechanics. My interest in physics eventually led me to work as a summer student in the group of Dr. Lilian Childress on NV centres where I became familiar with the field of quantum computing. During my Masters at ETH Zurich I learned more about quantum computing, and since I really enjoyed working with the TIQI group I decided to pursue a PhD here.

David Holzapfel, PhD Student

I studied physics at the University of Konstanz. I concluded my studies by investigating nonlinear dynamics of nanomechanical systems. During my Master studies, however, I got interested in quantum information and quantum computing. Therefore, after finishing my studies in Konstanz, I decided to shift gears and persue a PhD in trapped-ion physics. That is why I moved to Zürich to join the TIQI group, were I've now started working on the molecule project.

Alfredo Ricci Vasquez, PhD Student

I did my undergraduate studies in physics and electrical engineering at Universidad de los Andes, Colombia. There I did my physics thesis in quantum optics, using polarization and space variables to store information. After this I did my master studies at The University of Edinburgh, and my dissertation consisted is studying the use of randomized benchmarking to test ion trap digital quantum simulators. After this projects I decided that I wanted to work on quantum information theory using trapped ions, so I joined the TIQI group for my PhD.

I studied both physics and mathematics as an undergrad at Washington and Lee University in the USA. Between a summer with the nanofabrication research group at NIST and a class on quantum algorithms, I knew I wanted to dive into experimental quantum information processing during my Master's at ETH. Classes here have only solidified that interest, and I'm excited to be starting with the TIQI group.
