| Research Abstract |
In order to treat quantum advantage of multi-terminal quantum network, it is essential to use the quantum entanglement state among multi-terminal. In this research, I treated the distinguishability, the quantification, the classification, and the convertability for the quantum entanglement state among multi-terminal. Further, I showed the existence of the universal coding for quantum channel that well works for the one-input and multi-output case.
