__Abstract:__

Q-systems are unitary versions of Frobenius algebra objects which appeared in the theory of subfactors. We will discuss higher unitary idempotent completion for C*/W* 2-categories called Q-system completion and its inverse 2-functor called realization. We will explain several applications of Q-system realization such as generalized crossed product and K-theory of actions.
