# Kamil Korzekwa

### Group Leader

Scientific background:

I got my BSc in Physics and MSc in Nanoengineering from Wrocław University of Science and Technology, where I was supervised by Professor Paweł Machnikowski. Then, I joined the Centre for Doctoral Training on Controlled Quantum Dynamics at Imperial College London, where I pursued my PhD degree in Physics under the joint supervision of Professor Terry Rudolph and Dr David Jennings. Afterwards I did my first postdoc in Quantum Science Research Group at the University of Sydney, Australia; and a second brief one in the International Centre for Theory of Quantum Technologies at the University of Gdańsk, Poland.

Research interests:

My research interests are mainly focused on classical-quantum divide arising within various thermodynamic and information processing tasks. This includes exploring protocols that may exhibit quantum advantage, developing various approaches to capture the notions of reversibility and irreversibility in the quantum regime, and studying structural differences between classical and quantum theories. Thus, my research lies at the interface of open quantum dynamics, quantum information and resource theories.

### Postdoc

Scientific background:

I completed my MSci in Maths and Physics at the University of Bristol, under the supervision of Dr. Tony Short. My PhD studies at the University of York were supervised by Professor Paul Busch and Dr. Roger Colbeck. Following my PhD I joined the Quantum Resources Group at the Jagiellonian University, Krakow as a post-doctoral researcher.

Research interests:

During my PhD I focussed on questions related to quantum measurement and uncertainty. In particular I am interested in the interplay between measurement uncertainty, preparation uncertainty, and incompatibility how these impact our ability to do useful tasks. Since joining the Jagiellonian University I have been thinking about problems relating to magic resources, which separate sub-theories of quantum mechanics which can be efficiently simulated by a classical computer from the full power of quantum theory which cannot. I have also been working on aspects of quantum phase transitions and uncertainty.

### Postdoc

Scientific background:

I got my BSc in Physics from the University of Concepción, Chile, where I was supervised by Professor Michal Kurgansky. Then, I joined the Centre for Optics and Photonics (CEFOP) also at the University of Concepción, where I pursued my PhD degree in Physics under the supervision of Professor Aldo Delgado. I continued for a brief period as a postdoc in CEFOP and afterwards I moved for my second postdoc to the National Quantum Information Centre (KCIK) at the University of Gdańsk, Poland.

Research interests:

I am currently interested in developing the framework of resource theories and applying it to the study of quantum channels. I would also like to contribute to this development by proposing new fundamental tasks or characterizing classes of theories under mild assumptions. However, due to my previous research, I am still interested in a wide spectrum of research areas relevant for quantum information, such as causality, emergence of classicality, nonlocality, contextuality, randomness amplification, quantum discrimination and Bayesian inference. Finally, I would like to mention some fields that intrigue me, but are not closely related to quntum information: fluid mechanics, Nambu mechanics and classical gravity.

Scientific background:

I obtained my MSc (German Diploma) from TU Munich (TUM) after studies of Mathematics and Physics in Munich and abroad, followed by a thesis on open quantum systems in the Glaser group at TUM and the theory division of Max Planck Institute of Quantum Optics (MPQ). In addition I received an Honours Degree in Technology Management by the Elite Network of Bavaria (ENB) and was a Visiting Researcher at the Center for Quantum Technologies (CQT) of the National University of Singapore.

Research interests:

My scientific interests center around the mathematical structure of quantum physics, primarily open quantum dynamics in the language of quantum information. I especially like research in the context of decoherence or the general contrast between quantum and classical phenomena. My two favourite physical areas have always been quantum theory and statistical physics, so the emerging field of quantum thermodynamics is of great interest to me. Resource theories and quantum control are useful frameworks for my endeavors, in addition I love approaches that employ operator algebras, representation theory or Lie-theoretic methods. In summary: my passion are mathematical structures relevant in our quantum world and its transition to classicality.

### BSc student

Scientific background:

I graduated from III LO Gdańsk High School, where I completed an International Baccalaureate programme with extended courses in mathematics and physics. Following one year abroad, studying Electrical and Electronic Engineering at Imperial College London, I enrolled in Theoretical and Experimental Physics course at the Jagiellonian University, where I currently study and work on my bachelor thesis.

Research interests:

My interests cover quantum cryptography, the problem of quantum decoherence, the classification of quantum resources, and group representation theory. I am particularly interested in Lie algebra, symmetries in SU(2) and U(1) groups, and their application to quantum channels and quantum communication. In my current project, I explore the topic of information capacity and information loss in communication via quantum channels without a shared reference frame. Aside from my scientific interests, I am also interested in research in the domain of engineering, in particular microelectronics and the design quantum hardware.
