Quantum secured gigabit optical access networks [PDF]
Scientific Reports, 2015 AbstractOptical access networks connect multiple endpoints to a common network node via shared fibre infrastructure. They will play a vital role to scale up the number of users in quantum key distribution (QKD) networks. However, the presence of power splitters in the commonly used passive network architecture makes successful transmission of weak ...
