Outline of Final Research Achievements

I focused on the networked systems which each system is connected to other systems via quantum communication. My study was divided into three parts: (1) stabilization problems of classical or quantum systems via quantum communication, (2) estimation problems of initial quantum state under measurement records of the systems, and (3) generation problems of quantum correlation in the quantum networked systems.
The results are as follows: (1) designing the encoding and state estimator suitably, there were controllers that stabilize the networked system. (2) A quantum smoothing theory has been developed, which enables us to know what past state of the quantum system was. (3) A consensus algorithm was developed and applied to networked quantum systems, and the algorithm generates the quantum correlation among the systems. On the other hand, I characterized the connection which generates the quantum correlation between quantum systems by the transfer entropy.
