Check out the latest google invention.... A processor capable of doing in 3 minutes what summit (the most powerful computer in the world made in IBM) would have done in 10,000 years... It could change a lot of things in the world of crypto, such computing power.... And at the same time it will make it possible to achieve very beautiful things!
No their quantum computer is different to the quantum computers which would be a threat to Bitcoin. However if it were to be used against Bitcoin and we went on with the assumption that it could contribute to the networks processing power. Do you know how much money that quantum computer takes to build? Then you have running costs and maintenance and when considering these which could be used for more beneficial projects I doubt the government would be happy with Google processing some Bitcoin transactions on the network. Then its the problem of there only being one of these quantum computers in existence and looking at the price to both build and maintain the machine there would probably not be very many people who would be able to afford it which means it would have little effect on the difficulty of Bitcoin mining and all of this is assuming its appropriate to mine Bitcoins which it is not.
