there is also Normal Computing[0] that are trying different approaches to chips like that. Anyway these are very difficult problems and Extropic already abandoned some of their initial claims about superconductors to pivot to more classical CMOS circuits[1] [0]: https://www.normalcomputing.com https://www.normalcomputing.com [1]: https://www.zach.be/p/making-unconventional-computing-practical https://www.zach.be/p/making-unconventional-computing-practi...
