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? Brent On 4/27/2022 12:26 PM, John Clark wrote: In today's issue of the journal N

I found some stuff about you. Not very interesting, but somewhat explanatory. I gather you're subliminally jealous of my relationship with Carl Sagan, but for me it's not a big deal. I have a major regret that he didn't go through and publish what would have been my third citation during that p

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.
