Terahertz implies wavelengths less than a millimeter. Computers will
have to adopt some kind of asynchronous architecture to take advantage
of that. I wonder if there are any proposed designs for such computers?

In today's issue of the journal Nature researchers report they have
developed a material that is superconducting in one direction but is a
normal conductor in the other direction, a superconducting diode,
something that had previously been thought to be impossible. They used
a 2D layer of a compound made of bromine and niobium (Nb3Br8) that is
only a few atoms thick. It only works at liquid helium temperatures,
3.86K or below, but they're currently working on something that works
at liquid nitrogen temperatures ,77K, because liquid helium is about
as expensive as champagne but liquid nitrogen is about as expensive as
milk. But even at the lower temperature this is a big deal. Mazhar
Ali, the chief researcher, is quoted as saying "/Technology that was
previously only possible using semiconductors can now potentially be
made with superconductors using this building block. This includes
faster computers, as in computers with up to terahertz speed, which is
300 to 400 times faster than the computers we are now using/." I'm
sure this will also be of enormous interest to those wishing to make a
quantum computer.
