| Outline of Final Research Achievements |
In this study, we have studied on a link of remote quantum devices for the development of quantum repeater technology that contributes to long-distance quantum communication. In particular, we have succeeded in constructing a system in which a quantum entangled photon source and a rare-earth doped Pr:YSO quantum memory are each frequency-stabilized and connected via wavelength conversion after 10 km optical fiber transmission.
