Quantum Cryptography Should Be Part Of Your Security Strategy

The news that IBM

has used a quantum computer to solve a problem that that stumps the leading classical methods is another step on the road to what has become known as “quantum advantage”, where a quantum system solves a problem that cannot be solved by any amount of classical computation. For those of us in around fintech, the one problem that we really want to solve is breaking public key cryptography so that we can forge digital singatures, get access to bank systems and, of course, steal a lot of Bitcoin

Quantum Supremacy

This is important stuff. In the British government’s new technology strategy, quantum computing is one of the “priority” technologies and it is easy to udnerstand why. That point about solving problems beyond the reach of exisiting computers means that there is something of an arms race underway, with “quantum supremacy” as the goal.
