One of my colleagues read a paper about quantum computing techniques to solve complex optimization problems (the domain of complex mixed integer solvers) and tried it out for a financial portfolio optimization, replicating the examples provided by one of the quantum computing companies during a trial period.

The computer *did not* produce the same results each time, and often the results were wrong. The service provider's support staff didn't help -- their response was effectively "oh shucks."

We discontinued considering quantum computing after that. Not suitable for our use-case.

Maybe quantum computing would be applicable if you were trying to crack encryption, wherein getting the right result once is helpful regardless of how many wrong answers you get in the process.
