The trick here is that shifting the quantum states for different frequencies accelerate away from one another dramatically increasing the quantum fisher. Just hope that was what the builder of your in-boat clock was using to test frequency accuracy the next time you are out in the middle of the ocean at night.
I am not sure if I feel smarter after watching or that or stupider. Of course if I apply quantum principle to it, I think I can be both at the same time. AMIRIGHT!!
