Indeed, a friend of my was running experiments on quantum computing - the first 18 months on each run of his tests, as he moved between jobs and universities, was just setting up the necessary refrigeration systems (and generally building them from scratch each time). Only then could he even start building the experiment - total time to run it all seems to run across years.
