I was thrilled to see Arqit come of out stealth mode yesterday with the announcement of a proposed SPAC Merger that will take it onto NASDAQ. Congratulations to David Williams, David Bestwick, Barry Childe and the remainder of the hugely talented team at Arqit who have set about the vitally important task of making sure our global communications and data are safe from hackers as quantum the first computing capability is deployed. Also see my previous update on the quantum hacking threat that businesses are waking up to. http://techinsights.dentons.com/post/102g5jw/what-is-your-quantum-strategy
Within this decade quantum computers will likely be able to break PKI. Core business systems and networks must move away from using PKI – so we must do it once and do it right. So called post quantum algorithms are not mature enough to be relied upon and will introduce new complications, before being compromised themselves by either classical or quantum attack. No public key algorithm can ever be described as “Quantum Safe”. Symmetric encryption keys, and the AES256 Symmetric Algorithm which uses them are known to be secure against quantum attack. Arqit has found a secure way to use them at scale.
