In information and communication networks, transmission capacity and security are main technical demands that are required to be continuously and rapidly upgraded. To use the maximum physical potential of the network, one has to develop "quantum node technology" which enables us to control quantum states of light and matters to achieve the ultimate communication capacity and sensitivity. In this article, we review our recent progress toward this goal, in particular, the technical progress of the quantum control photonic signals and demonstration of new quantum communication protocols by using these technologies.
