About the Group

We are keen on all problems that involve quantum theory and interesting mathematics. In particular the group members have worked on:

– description of quantum entanglement in many body systems and quantum marginal problem using symplectic/algebraic geometry and representation theory

– classification of quantum statistics (anyons) on quantum graphs and quantum networks using algebraic topology

– characterisation of isospectral/isoscattering quantum graphs using representation theory of finite groups

– universality of quantum gates using Lie groups theory and number theory

– efficiency of quantum gates using ideas from the theory of random walks on compact groups

– membership problem for quantum gate-sets

Our research is funded by the Center for Theoretical Physics PAS and the National Science Center, Poland through Sonata Bis and Opus grants.
