How Quantum Communication Is Set to Revolutionise Cryptography

(SiliconRepublic) 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.
There will be no shortage of commercial applications for these advanced cryptographic mechanisms. 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 in Trinity College Dublin, we successfully implemented an algorithm that could achieve this level of security. That this took place during a hackathon – a sort of competition for computer programmers – shows that even enthusiasts without detailed knowledge of quantum physics can create some of the building blocks that will be needed for the quantum internet.
Financial institutions are already using quantum communication networks to make inter-bank transactions safer. And quantum communication satellites are up and running as the first step to extending these networks to a global scale.
The pipes of the quantum internet are effectively being laid as you read this.
