I'm not sure about their claim to having quantum computers, whats the technology they use? seems like just semi-conductors.

Google says/claims it has speeds 3600 times faster than a normal computer, seems as though google has just purchased from a company

that is  a copy of Bitcoin Asics. Also the theory of Quantum computers having dual position seems stupid, obviously it is

switching positions or its not actually doing anything ?

This has been covered many times here.  So far it does not do anything faster for the same money as conventional computing.  And at worst it is not even what they say it is.

Let's not get d-wave and "quantum computing" mixed up. Nextgen quantum computers will perform specific calculations at speeds unknown to to the fastest of today's supercomputers.

We should not be talking about nextgen quantum computing too seriously before we even know if the first generation is real. 

Also quantum computing is really not applicable to SHA-256.

Quantum computing is real. That I do know.

Isn't it ideal "in principle" for things like breaking encryption?

So far that has yet to be proven.  See my link above.  That is not the only one, search a little yourself. 

Secondly quantum computing is not ideal "in principle" for breaking encryption.  It has yet to solve a single hash or be used to break ANY encryption method, even weak ones.  How could it be possibly considered ideal for this task?

These things take time, relax and take a deep breath.

NSA is also working on one: http://rt.com/usa/quantum-computer-nsa-encryption-100/

They haven't proved it's real yet.

I don't understand very much, but it sound's very doubtful, that quantum computers will be useful any time soon :
