Tokyo QKD Network was inaugurated in October 2010 in a part of the NICT open testbed network "Japan Giga Bit Network Extreme (JGN-X)". Since then, QKD systems, QKD network technologies and various applications have been developed and tested on it. Some of these technologies are going out into user premises in 2015. Tokyo QKD Network will be offering a platform for developing security certification technologies, next generation QKD systems and new applications.
