| Research Abstract |
For a general "quantum network" system, each node of which is given by a quantum system, a designing theory of a feedback controller that enhances quantum correlation between the nodes was clarified. Also a complete characterization of the quantum system generating maximal correlation was obtained. Moreover, a quantum controller enhancing a squeezed light field was experimentally demonstrated.
