Dagomir Kaszlikowski Group

Our main research interest can be summarised in one word: CORRELATIONS. We are interested in correlations because, from an orthodox point of view, quantum theory is nothing more than a theory of correlations in space and time. Correlations are essential in studies of information aspects of quantum theory such as quantum nonlocality, contextuality and quantum information processing in general.

Recently we have also started investigations into the origins of ‘quantum supremacy’. Our approach is based on alternative formulations of quantum theory as local quasi-stochastic processes on quasi-probability distributions. The Holy Grail of this aspect of our research is to find new quantum algorithms and to better understand why quantum computers are more powerful than classical Turing machines.

We are also interested in the social, economical and environmental impacts of rapidly evolving quantum technologies.
