The Quantum Internet Is Already Being Laid

By IQT News posted 21 Feb 2020

(Metro.News) There has been rapid progress in the development of quantum communication networks, and a master network to unite them all called the quantum internet. Just as the internet as we know it followed the development of computers, we can expect the quantum computer to be accompanied by the safer, better synchronised quantum internet.
But how could this quantum internet be built anytime soon when we currently can only build very limited quantum computers? Well, the devices in the quantum internet don’t have to be completely quantum in nature, and the network won’t require massive quantum machines to handle the communication protocols.
One qubit here and there is all a quantum communication network needs to function. Instead of replacing the current infrastructure of optical fibres, data centres and base stations, the quantum internet will build on top of and make maximum use of the existing, classical internet.
The world of finance, in particular, looks set to benefit as the quantum internet will lead to enhanced privacy for online transactions and stronger proof of the funds used in the transaction. Recently, at the CONNECT Centre for Future Networks in Trinity College Dublin, an algorithm was successfully implemented that could achieve this level of security.
