The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; .

A novel secure communication network with quantum key distribution in a metropolitan area is reported. Different QKD schemes are integrated to demonstrate secure TV conferencing over a distance of 45km, stable long-term operation, and application to secure mobile phones.
