We may find out sooner than we'd like to think. Quantum Computing Is About to Overturn Cybersecurity’s Balance of Power - Singularity HUB Think about this for a bit. We've all seen the charts and graphs that show us how long it would take to break complex passwords. Here's an example: Password Recovery Speeds Now, imagine having a password that would take 631 Billion years to crack using a large scale distributed network. With quantum computing, this could be conceivably be cracked instantaneously. In essence, our existing methods of encryption and protection are for naught when it comes to quantum computing. Now, is this something that JQ Public will be able to afford? No, not for quite some time. But companies are already in a rush to be the first to create a scalable system and I'm sure governments are drooling at the prospect of what these systems can do. The cybersecurity aspects alone of having such a system is a spy agency's wet dream in the making. While the thought of quantum computing is rather exciting, for the folks on the security side of the house, their nightmare is just beginning.
