The Quantum Resources Group was dissolved on November 30, 2023.

​

Who we were

​

We were a theoretical physics research group established in January 2020 at the Jagiellonian University in Kraków, Poland. We specialised in quantum information science and formed a part of the Polish quantum computing consortium supported from 2020 till 2023 by the TEAM-NET grant funded by the Foundation for Polish Science.

​

What we did

​

Recent progress in experimental control over noisy intermediate-scale quantum (NISQ) systems may soon bring the advent of new technologies, whose operation will be based on purely quantum effects and that will be able to overcome current limitations of electromechanical systems and information processors. From a theoretical point of view, the first step to achieve this is to identify which components of quantum theory can provide such an advantage. In other words, we need to recognise what actually constitutes quantum resources. Once the relevant resources are identified, the next step is to characterise them, i.e. understand when different resources can be interconverted and how efficiently this can be done, which is captured by the mathematical framework of resource theories. Finally, there is also the third essential step: finding optimal ways to experimentally implement protocols exhibiting quantum advantage, while taking into account realistic constraints.

​

Our goal

​

The general goal of the Quantum Resources Group was to develop a theoretical framework underpinning quantum technologies, with a particular focus on quantum computing and quantum thermodynamics, by investigating all three aspects of quantum resource theories: identification, characterisation and implementation. These research goals were pursued by realising several objectives that included:

​

• Identification: investigating possibilities for quantum advantage within thermodynamic scenarios and finding operational interpretations for coherence resources.

​

• Characterisation: determining the constraints for manipulating magic states and developing quantitative methods to characterise thermodynamic irreversibility.

​

• Implementation: constructing experimentally feasible protocols for probing quantum thermodynamic phenomena and devising classical simulation algorithms for the certification and verification of the NISQ devices.
