The conference Towards Ultimate Quantum Theory (UQT) is arranged by International Centre for Mathematical Modelling in physics, engineering and cognitive sciences (ICMM) at Linnaeus University in Växjö, Sweden. This is the 19th Växjö conference devoted to quantum foundations and applications of quantum theory, especially quantum information and probability. It is devoted to quantum foundations (including philosophical issues), experiment, and recently developed quantum technologies (with emphasize of their foundational aspects).

In spite of its tremendous success (both theoretical and experimental), the present quantum theory cannot be considered as the ultimate theory of micro-phenomena. It suffers of a variety of fundamental problems. Quantum mechanics is a nonrelativistic theory and its relativistic generalization, quantum field theory, suffers of divergences. But, of course, the biggest black cloud on the quantum sky is the impossibility to unify presently existing quantum theory with general relativity. The conference will be devoted to searching of new ways to creation of the ultimate quantum theory. However, since this project can take very long time (and even it may happen that is would be never finished), the conference also covers all traditional foundational topics: interpretations, mathematical apparatus, experiment, philosophy.
