Link: New Scientist Quantum computer works best switched off – News.

Even for the crazy world of quantum mechanics, this one is twisted. A quantum computer program has produced an answer without actually running.
The idea behind the feat, first proposed in 1998, is to put a quantum computer into a “superposition”, a state in which it is both running and not running. It is as if you asked Schroedinger’s cat to hit “Run”.
With the right set-up, the theory suggested, the computer would sometimes get an answer out of the computer even though the program did not run. And now researchers from the University of Illinois at Urbana-Champaign have improved on the original design and built a non-running quantum computer that really works.

Ya know – you think the Quantum world can’t get any weirder.

It’s not an unexpected result, but it’s still amazing to me that it actually happens. Like entanglement, it’s another verification that Quantum Physics is the proper way to view reality. So… two things can be true at the same time, faster than light travel is possible, we all exist in all places and at all times…

Now we just have to figure out what it means.
