There have been attempts to make these SFQ circuits work for ages, eg see this from 1999: https://www.researchgate.net/publication/3310945_Rapid_Single_Flux_Quantum_T-flip_flop_operating_up_to_770_GHz https://www.researchgate.net/publication/3310945_Rapid_Singl... What I want to know is, what were the problems that prevented them succeeding before, and have they been overcome now?

Dated (2005), but this report seems comprehensive: https://www.nitrd.gov/pubs/nsa/sta.pdf https://www.nitrd.gov/pubs/nsa/sta.pdf

  I think I've read about Josephson junction superconducting transistors in the mid-80's. And it wasn't in a cutting edge journal.
