>>9882329Quantum computers are in many ways worse than digital.
You've probably seen all the proofs by excited cryptologists who show you how_certain_ algorithms perform better and indeed in an entirely different complexity class using a quantum processes.
What you probably haven't seen is all the proofs where the quantum computing is worse for the most common processes. Not just a little worse, again an entirely different complexity class.
So in the end you'll end up with some kind of hybrid quantum/digital processor.
We've pretty much reached the limit. The future now is in clustering and efficient ECC.
