Several at the meeting were aware of Likharev's rapid single flux quantum (RSFQ) superconducting logic. They agree that it is a very interesting development, and further that it is fairly certain to work well.
|
However, they feel that the requirement for liquid helium temperatures is a severe impediment to widespread utilization, and without commodity production it is unlikely to be economic.

According to Stan Williams, recently Likarev came to Hewlett Packard.
|
|
He offered HP all of his patents, only asking that they develop the technology.
|
|
But HP management still declined. Williams quipped that if some company decided to produce RSFQ technology, somehow assembling the $100 million or so required in start-up capital, the day after they produce their first devices it would pronounced a great success, but on the second day the company would fold financially.
