Even for the crazy world of quantum mechanics, this one is twisted. A
quantum computer program has produced an answer without actually
running.
…
This scheme could have an advantage over straightforward quantum
computing. “A non-running computer produces fewer errors,” says Hosten.
That sentiment should have technophobes nodding enthusiastically.

computer works best switched off
While it's true that a computer turned off produces vast amounts of
nothing really fast, so does a burned out light bulb. And the very fact that
there's still a program means there are bugs (proof? “Every program has at
least one bug and can be shortened by at least one instruction—from which, by
induction, one can deduce that every program can be reduced to one
instruction which doesn't work.” Q.E.D.”) so it's still far from evident that a
non-running quantum computer will have fewer errors than a running quantum
computer.
I guess these guys haven't heard of Heisenbugs.
You have my permission to link freely to any entry here. Go
ahead, I won't bite. I promise.
The dates are the permanent links to that day's entries (or
entry, if there is only one entry). The titles are the permanent
links to that entry only. The format for the links are
simple: Start with the base link for this site: https://boston.conman.org/, then add the date you are
interested in, say 2000/08/01,
so that would make the final URL:
https://boston.conman.org/2000/08/01
You can also specify the entire month by leaving off the day
portion. You can even select an arbitrary portion of time.
You may also note subtle shading of the links and that's
intentional: the “closer” the link is (relative to the
page) the “brighter” it appears. It's an experiment in
using color shading to denote the distance a link is from here. If
you don't notice it, don't worry; it's not all that
important.
