It's also important to realize that quantum in the gate is currently 
pretty primitive. We're still running only a subset of tempest because 
the rest of it doesn't work on quantum. Grenade doesn't yet include 
quantum support (though that's still not passing either).

I would highly encourage some quantum experts to invest time in 
enhancing gate tests in tempest so we can catch these kinds of things in 
the future.
