    Use cases are generally problems with very large amount of factors that are not feasible to calculate with normal comouters, think about chemical/medicine simulation and logistics optimization or public transport timetables.

      So that’s the part that gets me stuck. There is no clear answer and it has no way to check the result as QC aren’t capable of doing so (otherwise they wouldn’t be using QC since they can only be based on binary inputs and binary guesses of true / false outcomes on a massive scale). How can it decide that it is “correct” and that the task is completed?

      Computations based on guesses of true / false can only be so accurate with no way to check the result in the moment.

        Yes, took me months to see that too! The point of the chances is though, with some problems you don’t need a definitive answer. Having a solution that solves 95% of your problem can be enough for the problems you would use a quantum computer in the first place. In other cases, your chance is somewhere between 99 and 100 percent so you practically still have a definitive answer.
