Well, I can agree with the term "expensive", but I'm not sure what you mean
by "finicky". Are you saying they only work sometimes? It seems a bit
hand-wavy to say that.

I've seen quantum computers before. They are room-sized, but not that big.
I still find the term "quantum annoying" rather imprecise.

Rob
