With the advent of powerful quantum computers, much of our cryptography will become insecure, leaving our data and communication unprotected and vulnerable. The scale of required changes is both complex and extensive. This is why all government organisations and IT suppliers need to start preparing now to mitigate the risks quantum technology poses to cryptography.
