@darkuncle OMG. I just googled Jon Dowling. We went out of touch around 15 or so years ago. I never learned until today that he passed away in 2020. 
Jon and I worked together when he was at Caltech/JPL. He was a pioneer in #quantum #engineering and #computing. He led a small group of brilliant researchers in my Computing and Information Systems section. They were so far ahead in thinking about applications of #QC that senior management mostly considered the work too theoretical and/or controversial. I mostly tried to run interference for them and clear the brush out of Jon’s way. He once taught me the “Six Beer Quantum Rule” — you can only understand quantum tech after you’ve had six beers. (The proof is left to the reader.) I feel exceptionally lucky to have known him.
