ML4Q&A - from the lives of quantum physicists – Details, episodes & analysis

In this episode, Mira and Chris talk with Markus Müller, a member of ML4Q and Professor at RWTH Aachen University and Forschungszentrum Jülich. Markus, an expert in quantum error correction, explains its importance in building large-scale quantum computers. He has supported pioneering logical qubit experiments on various platforms, including ion traps and superconducting qubits. They also discuss his recent work on avoiding mid-circuit measurements, a technique that benefits certain architectures and chip designs.

In this episode Mira and Chris talk to Silvia Pappalardi, who joined ML4Q as a junior professor last April. Silvia heads the Qhaos group (spelled with a Q) and introduces our listeners to the topic of quantum chaos which might be a bit intimidating for many of us. So, join Chris and Mira as they get some intuitive explanations from Silvia about concepts like thermalization and ergodicity and understand how these concepts relate to entanglement.

We continue to feature some of our experimental physicists. In this episode, we talk to Jan Klos, PhD student and associated member of ML4Q. Jan - who is almost done with his PhD thesis - performed his project in the group of Hendrik Bluhm and Lars Schreiber at the JARA Institute for Quantum Information. In the episode, Chris talks with Jan about going from a Master project in simulating quantum dot spin qubits to a PhD project fabricating them. They also discuss outreach, student supervision, thesis writing and working with engineers.

We continue to feature some of our experimental physicists. In this episode, we talk to Annika Kurzmann, Junior Principle Investigator at RWTH Aachen and associated member of ML4Q. We talk abour her work on optical quantum dots during her PhD and bilayer graphene quantum dots in her postdoc and how she is now bringing this together to detect single electron dots in graphene. We also discuss the Ruhrgebiet, tenure tracks and starting a lab during the pandemic.

We continue to feature some of our experimental physicists. In this episode, we talk to Beata Kardynal, group leader at Forschungszentrum Jülich and at RWTH Aachen. We discuss her career and her training in electronic devices to using these devices to couple to single photons. She reveals her favorite materials and how she didn't see a strong distinction between physics and engineering from the start.

In a new podcast episode of ML4Q&A, Kathrin Dorn (PhD student, Egger group) speaks to Dagmar Bruss, professor at the Institute for Theoretical Physcs III in Düsseldorf. They talk about Dagmar's passion about quantum information theory, how a coffee break in Oxford changed her research focus to quantum key distribution, her experience with the impostor phenomenon and how she got involved in a supercosmos project in astronomical technology. 00:00 intro 01:35 from astronomical technology to quantum information 06:23 working at ISI in Turin and joining talks by Grover and Shor 08:10 from experiment to theory 10:38 how is your working day? 14:43 struggles and experiencing the impostor phenomenon 19:24 work on quantum key distribution 25:27 ongoing work in ML4Q 32:28 1 or 2?

ML4Q&A continues featuring theoretical physicists in ML4Q. In the second episode, Chris Dickel is talking to David Gross, professor in Cologne and vice spokesperson of the ML4Q cluster. David's research interests lie on the application of rigorous mathematical methods to problems in quantum information theory and many-body theory. We talk about his career path, advising student projects in theoretical physics, teaching quantum mechanics and the Google event he was probably never invited to.

The first episode of ML4Q's podcast - ML4Q&A - is now online! Our guest is Martino Calzavara, a PhD researcher in the PGI-8 Institute for Quantum Control at the Forschungszentrum Jülich. We talk about him moving to Germany for his PhD and learning German, his experiences in academia as part of ML4Q as well as ultracold atom systems and how quantum control could help to cool these. We also talk about his simulations of these systems and machine learning, conferences in the times of a pandemic and Italian Pannetone vs. Pandoro.
