This all sounds like some bullshit.
What was the solution?
> Critically, the quantum states that compose these officers have a special relationship called entanglement, which involves a correlation between different entities. If a red king is entangled with an orange queen, for instance, then even if the king and queen are both in superpositions of multiple regiments, observing that the king is red tells you immediately that the queen is orange.
Okay.
> The theory seemed to work, but to prove it, the authors had to construct a 6-by-6 array filled with quantum officers. ... > When the researchers repeated the algorithm over and over, the puzzle array cycled closer and closer to being a true solution. Eventually, the researchers reached a point where they could see the pattern and fill in the few remaining entries by hand.
So what is the goddamn solution???
There isn't one, cause that's all bullshit and they didn't solve anything. I can claim I solved all the proved unsolvable math problems that way (I just superpositioned everything quantumly so everything has a solution).
Grant money well wasted.
