Quantum computer sighted

It occurred to me this afternoon that I had no idea what a quantum computer physically looked like.

So I Google it, and found this photo from an Engadget article earlier this year, showing the innards of an IBM 50 qubit quantum computer:

Cool.

Actually, it does literally need to be very cool - but the article does a very poor job of explaining how exactly it is cooled down to liquid helium temperatures.   Does the whole thing sit in a liquid helium bath?
