The one who rules the quantum computer rules the world.
Forget the AI, zoom in and explore the meanders of the quantum world.
I hope you have all read by now that top tech companies are working on a Quantum Computer. And it is going well.
*Why should you care?*
IF or rather WHEN we break the quantum barrier and make the computers error-prone, it will impact the world as we know now.
Why?
Security.
Whenever you talk to a security specialist they will tell you that no IT security solution can guarantee 100% protection. It can "decrease the surface of the attack" or "decrease the ROI of the attacker" - what does it mean? Simply put, there's an assumption that if it would take a hacker 34 years to break encrypted data - the data is protected. After all "ain't nobody got time for that", right?
Which does not mean the encryption is unbreakable. An encrypted string is nothing more that a long string of random letters, numbers and signs. The computer that would want to break such a string would have to work through all possible combinations of all the possible signs. Which you can imagine takes time and effort.
For an "average" computer.
But not a quantum one.
Calculations that would take a regular computer 34 years can take quantum computer hours or minutes.
