| Outline of Final Research Achievements |
In this research project, mainly the following two results have been obtained. (1) Based on the systems and control theory, I have elaborated a general theory for characterizing and synthesizing a decoherence-free subsystem, for the general linear quantum systems. (2) A general theory to design a feedback controller for generating a DFS was obtained. (3) Using the important notions ``zeros (of a transfer function)" or more generally ``zero-dynamics", I have constructed a theory for building a DFS as a quantum memory for general linear quantum systems.
