Start-up Meeting of NICT Commissioned Research (27 and 28, October 2011)

The Startup Meeting of NICT Commissioned Research was held on 27 (Thu) and 28 (Fri) October 2011 in Tokyo. All the teams and the reviewers of the subjects got together to share the missions of the projects, and to get to know each other for tight collaboration. It is far past the period when each team concentrated only their own subject. It is now the time we realized the interoperability between the systems developed, and integrate them into a practical quantum network.
