Far from an expert on this subject (or really any other subject … 😉 ) @fucho80, I have been reading about the pending release of computers with this capability for the last 2 years or so, since R & D (research and development) on them has been very active for quite some time. As you cite here, there are many others, besides Google, who are in this “race” and we’ll likely all find out soon enough who the “winner” is going to be.
To what end? Only our sovereign Lord ultimately knows, but man views this as a huge technological step forward given the exponential increase in processing power these quantum computers represent. Perhaps you and I could agree that, as with most any technological advance, there will be some positive applications of it. And some that will be very sobering, in terms of what they will represent for our future …
I hope all is well for you and yours. God bless you!
