Quantum computing cooling challenges

What a great article. Teaser, I posted it here as it's about as hard core cooling as it gets:

Well, there are two challenges...
* Cooling is "easy enough"... build the whole thing into a space lab/satellite in an orbit that keeps it in the shade... the ambient temp of open space should be cold enough
* However, the 2nd challenge is bit harder... First, you have to find a DeLorean...
