Within the next few years a quantum computer will crack encryption. This once in a generation event will, in a single moment, render the entire world’s data vulnerable to theft and exploitation. While every cyber security team must deal with everyday threats, quantum computers are the ‘mega-threat’ to which their attention must now turn.
Quantum computers work differently from today’s ‘classical’ machines. This is because they are extremely good at performing vast amounts of computations in parallel whilst today’s computers have to solve problems one at a time. As such, quantum machines can derive knowledge from small datasets, which will allow them to break encryption.
