I think if there is someone I would not want to own a quantum computer, next to Lockheed Martin, thats Google. They already are at least 10 years ahead of everyone else.
If they are the first to spend the money on seriously making use of quantum computers, who on earth is going to stop them if they decide to make bad use of their power?
I'd really like to see this power in a companies hands that is not against the concept of privacy.
