Michał Oszmaniec Quantum Information Research Group is a website of the Quantum Information Group led by dr. Michał Oszmaniec. We study quantum information under the restrictions on resources that are allowed to be used. Such limitations arise from the difficulty to implement in practice the most general quantum-information protocols. In our research we use the combination of convex analysis, group theory, high-dimensional analysis and numerical simulations.

 Meet the team:


Principal Investigator

I am a theoretical physicist specialising in quantum computing, quantum information and mathematical physics.

The main topics of my current research are:


  • Quantum computation with fermions
  • Random quantum circuits, approximate t-designs, complexity of quantum states and unitaries
  • Characterisation and error mitigation in near-term quantum computers
  • Efficient classical simulation of noisy large-scale quantum systems, with applications to quantum supremacy and quantum simulations
  • Understanding the relative power and usefulness of POVMs and projective (von-Neumann) measurements in quantum information and quantum computing
  • Role of various kinds of correlations (such as contextuality, non-gaussianity) for quantum computation
Adam Sawicki
Senior Scientist

I am a mathematical/theoretical physicist specialising (among others) in quantum information theory. For a few last years I have been particularly interested in theoretical aspects of quantum computing.
The main topics of my current research are:
  • Efficient quantum gates
  • Variants of Solovay-Kitaev theorem
  • Random quantum compilers
  • t-designs and epsilon nets
  • applications of control theory in quantum computing
  • geometry of quantum correlations
Marcin Kotowski

I’m a mathematician (PhD from University of Toronto, 2016) with main research focus on probability theory. These days I’m interested in mathematical aspects of quantum information theory / quantum computing and more broadly in the set theoretic union (and sometimes intersection) of probability, quantum information and data science / machine learning.

Jan Tuziemski
Postdoc / Quantum Software Engineer

I am broadly interested in studies of quantum systems affected by noise. Having worked on information transfer in decohering quantum systems, dynamics of classical-quantum hybrids, as well as novel applications of the Feynman-Vernon approach, I now focus on noise characterization and error mitigation techniques for NISQ devices.

Postdoc / Quantum Software Engineer

Susane Calegari
PhD Student

My key areas of interest are classical simulation of quantum computers, quantum computational resources, quantum foundations, and quantum contextuality. I am a theoretical physicist with a master thesis on conformal invariance applied to quantum field theory and gravity. My research in quantum information has been on the understanding of the structure of correlations in multipartite systems. Now, as a Ph.D. student, I want to focus my studies on the role of contextuality as a resource for quantum computation.

Joanna Majsak
Master Student

I am a physics student, learning about different aspects of quantum information and computing and drawn to elegant mathematical models. I aim to better understand the possibilities of NISQ devices. Currently I am working on mitigating measurement errors in them.
