Secure & Un-hackable Computer Network is Close to Reality
Scientists have developed a method of securely communicating between multiple quantum devices, bringing a large-scale, un-hackable network closer to reality.
To date, communicating via quantum networks has only been possible between two devices of known provenance that have been built securely.
"We're in a technology arms race of sorts. When quantum computers are fully developed, they will break much of today's encryption whose security is only based on mathematical assumptions," said Ciaran Lee, from University College London in the UK.
"To pre-emptively solve this, we are working on new ways of communicating through large networks that don't rely on assumptions, but instead use the quantum laws of physics to ensure security, which would need to be broken to hack the encryption,"...
