Implementation Security of Quantum Key Distribution
Kiyoshi Tamaki · NTT technical review · 2017
Quantum key distribution is the ultimate cryptography in that it is theoretically secure against any possible eavesdropping.This ultimate security is an attractive feature, and companies and organizations in several countries, including Japan, are working on the deployment of networks for quantum key distribution.However, further research is needed to achieve the ultimate practical security, rather than security in principle.In this article, we introduce our recent research activities toward achieving the ultimate practical security.
