| Research Abstract |
The main theme of this research is to design or realize quantum systems with optics systems for showing the effectiveness of the quantum filter theory or the quantum control theory. In particular, the actual objective is to clarify the indispensable property of systems for the quantum state estimations or generating and holding quantum entangled states based on the quantum filter theory and the feedback control theory. The results of this research is to specify a quantum optics system, a combined system composed of a quantum optics system and a spin system, and the corresponding control strategies. We also succeed to derive the corresponding quantum filter equations. With this equations, we can show the effectiveness of the quantum state estimation by the actual experiments or that the feedback systems can generate the entangled states by numerical simulations. Moreover, we can also prove the controllability of a quantum feedback system.
