Future quantum computers will one day bring us many great benefits. Unfortunately they will also break many of the cryptographic protocols on which current Internet security depends. Google’s quantum supremacy breakthrough notwithstanding, this is still most likely many years off. However, sensitive data intercepted and stored today, or long lifecycle...
The UK Quantum Showcase demonstrates why others around the world are seeking to copy the UK’s quantum technology approach. It’s little surprise that the UK government is providing additional funding of £315m over the next 5 years. The 2018 UK National Quantum Technology Showcase took place in the prestigious QEII...
The internet has changed so much of our human activity for the better. But its very existence is now threatened by quantum attack.
The emergence of quantum computing means that the encryption techniques used by the Internet will be hacked. There are a variety of solutions to this problem emerging. The ArQit system offers a significant contribution to keep the Internet safe.
By injecting quantum safe keys into the major peering points at the heart of the Internet, we can keep the control planes of the World’s network safe. Large corporations can keep their cloud applications safe. And one day, we will be able to get quantum keys to households and even mobile phones, through R&D we are conducting to create an interface between satellite and metro fibre networks.
The ArQit project brings together three powerful technology innovations:
Advances in small satellite technology means that it is now possible to launch and fly robust, fully-stabilised, secure satellite platform constellations in low earth orbit at low cost.
Advances in optical technology means that accurate and powerful instruments can be used in space and on ground to transmit and detect photons to the required level of accuracy.
Our innovation in creating quantum generation devices brings commercial communications into the quantum realm for the first time.
