I have also made some amusing youtube videos on the subject of Josephson junction dynamics which can be found here:
Note these videos are only probably amusing if you have already studied JJ dynamics in detail. Otherwise they probably make very little sense.
I have several published papers on JJ amplifiers, which can be found on my Google Scholar page here.
While Josephson Junctions have been a very interesting and useful technology for several decades, and have helped me make a living, I think that work on low temperature technology is mostly a waste of time and money. I probably should not say this, since it still helps me make a living, but I think quantum computing is, like its classical JJ computing cousin, a giant boondoggle. Anything at a temperature below 77 kelvin(the boiling point of liquid nitrogen) is, in my view, a waste of time at this point in human history.
