The point is I did my PhD on superconductivity. Well, just experimental, 
not theory.

D-wave have good material on their site explaining how the circuity works:

Still can not quite understand the physics behind this. That may change 
once I put more time into the subject and reading the above article. 
Much more time.

And small remarks.

1. If a governement of super-hiper huge influential company needed to 
have a super-hipercomputer that must work cooled by liquid Helium - that 
is not a problem for them. We can not have it.

2. The thing is rather to create a toy that will work at 300 K. That 
involves research on semiconductor nanostructures (who knows if that 
makes sense at all, for this aim)

3. Do we need that at all? For what a f*ck? Would not we should first 
know what for we need that? OK, this is question without an answer...
