If the targeted atom loses more energy than is put in; wouldn’t the system continually lose energy, and increase its entropy?
Again this is Sabine I struggle to know what she is thinking at times as she seems to confuse herself.
I get the impression she thinks you wait for a random QM fluctuation to excite an atom (which cost you nothing) and then hit that excited atom getting twice the energy. I think she then views the atom drops back to repeat the process so it's not losing energy like you suggest but stealing it from QM or the universe ... she has a perpetual machine extracting energy with no change in the universe system save the temporary excite state.
Unfortunately she keeps ignoring the "if you knew" bit would require a measurement and that costs more energy and increases entropy more than the energy she would get back.
