Quote: "In our measurement setup, we see such resonances, with Q 30-50, likely associated with the superconducting cable which runs between the sample and the amplifier. This implies an enhancement of the photon production rate by a factor of 1000-2000, consistent with what we observe." What they seem to be saying is that the photon production rate with the resonance is 1000-2000 times what it would be without the resonance (if I read it correctly). That doesn't really say anything about the ratio of input to output power. In fact the overall tenor of the paper seems to be that they were happy to detect the signal at all, not that they had a new source of power.
