Quantum technologies in the telecommunications industry

Quantum based technologies have been fundamental in our world. After producing the laser and the transistor, the devices that have shaped our modern information society, the possibilities enabled by the ability to create and manipulate individual quantum states opens the door to a second quantum revolution. In this paper we explore the possibilities that these new technologies bring to the Telecommunications industry.

Quantum Technologies for future Quantum Optical Networks

The recent evolutions in the convergence of QKD and classical communication systems are described, together with the relevance of SDN as a suitable approach for a real integration between QKD and WDM networks. Preliminary experimental results on a discrete-variable QKD prototype working in the O-band co-propagating with 40 50-GHz C-band information channels are reported, showing the capabilities of QKD in short/medium reach optical networks.
