Trits Making a Comeback?

Maybe.  "Trits" – three-state logic, as opposed to the more familiar two-state logic bits, have a poor track record in practical development.  Of course, that was during the 1960's-70's in the USSR, where many good ideas got ground up by overwhelming bureaucracy, so maybe in the 21st Century we can finally get it to work.  Anyway, go read the Article at Quanta online magazine.

Nah, those three wheels just aren't going to cut it.  Cute picture though.  I'll guessing that three-state logic won't work out this time either, though the jury is still out and the idea is very much worth looking into.
