Disregarding custom OS that will probably be made first.
This is not how this works. One day in the future, when quantum computers have matured enough to do something actually useful instead of just quantum benchmarks, they still will not be general purpose systems.
The situation will be more like video cards at the moment: it would be a subsystem doing something very specialized and limited, being controlled by a driver handing over certain jobs from the OS of the real processor.

Quantum circuits aren’t general-purpose computers—they’re added to conventional computers to allow them to perform a small handful of algorithms more efficiently. I don’t believe any of those algorithms would benefit the basic features of an operating system enough that it would make sense to modify an OS to require the use of one.
(Although I could totally see Microsoft doing something like only licensing their circuit’s drivers to run on Windows.)
neither, you need to have a totally new architecture
Finally we can tell the console people we will have PC 2!
I think quantum computers may be impossible. But if they are possible, they will be a USB/PCIe accessory that works alongside an ordinary processor running an ordinary operating system.
I expect Linux will have a driver for quantum computers before Windows.
how can a thing that has existed for years be impossible?
What exists is a weird engineering experiment that runs some synthetic tests that are designed to return a number that you plot on a graph which you show your investors. And it costs all the money in the world and then some.
Not only there is no practical use for all that, there are debates about what the practical uses might even be in theory for something that nobody really sure is happening.
Quantum computing is a pipe dream, it’s never going to happen.
it’s happening but it’s probably not the thing that you think it is
It’s already happening so… L take?
