By civilian, do you mean IBM, Google, HP, and Microsoft? The cheapest civilian quantum computer is $15 million.

Large enterprise quantum computers suffer from the same problems that I previously described. The military has quantum computers, but they are used for certain tasks. Just the same as super computers. When they need reliable calculations performed a supercomputer is likely to do it. Quantum computing is used to solve more time intensive tasks that would take even a supercomputer a long time to complete.

They both have their place and value. Maybe in 10 years we will see more of the problems ironed out in quantum computing.
