Well, except nothing perhaps but hurtling at 60 percent of the speed of sound, at ten percent of normal oxygen levels, at 30 degrees below zero packed in with a 160 other sardines in zorris and hawaian shirts, a third of whom are presumably infected with measles.
You can read on airplanes???!

OK. Well, I thought I could've digested the two papers by this time. But I've failed and will probably give up for now. It's still entirely unclear to me how the 3 level system's dark states facilitate the finer-than-diffraction-limited resolution. So, I can't place the OR gate example into the context of the laser lattice and my 1st basic question about energy state transitions via different energy photons.
I believe I grok your point about any given "degenerate" state being "computed over" as if it is or could be real[ized], just so that the solutions are meaningful. But in the context of microscopy, distinguishing things below the resolution allowed by the drive beam, I remain completely lost.
Hopefully, I'll try again soon ... maybe on an airplane flight when I have nothing to distract me. 8^)

Excited eigenstates typically exist, but they would give configurations that were wrong like "D 0 0 -> 1". Suppose one wanted to find the key for a complex encryption circuit. A gate encoding that completely favored one gate, P(X) = 1, would not enable search.
