There are/seem to be very specific scientific applications, mostly around simulation of other systems whose hamiltonians map nicely to that of the computer. For almost everyone on the planet that isn’t very useful, but for that small handful it can be a game changer. … doesn’t contribute much here, but worth knowing! It’s exciting either way.
