China claims it has developed a quantum radar that can detect stealth aircraft

Regarding your last point, I think the paper simply meant to say that such systems would be more effective in an EW-heavy environment or in a setting that produces lots of radar clutter. I don't think the abstract specifically mentioned that longer ranges and higher resolutions could be achieved with relatively lower power.

Every point I made is a very straightforward implication of "exponential improvement over unentangled illumination." In fact, I'm being pretty conservative about what this can do. It might be possible to not just track low RCS targets the moment they appear on the radar horizon, but to probe the material properties of their RAM paint with sufficient detail to tell the batch they came from.

Do you have a link to the full paper? There is no way you've extracted all that from a four-line abstract.
