It increases the rate of production of neutral antihydrogen from antiprotons and positrons by a factor of 8. It doesn't increase the efficiency of production of antiprotons, which is the extremely inefficient, energy intensive part.
If you have a process where it takes 5MW to produce one component and 80KW to convert that component into the final product, and you increase the efficiency of the second step 8 times so it only takes 10KW, that's real and awesome, but still almost irrelevant to the overall efficiency of the process. I have no idea what the actual numbers are, just stating the general concept.
They cut production time to a given number of anti-atoms from 10 weeks to 7 hours by improving the electron cooling, just from this fact it is a bit rich to insist the anti-proton generation is the limiting factor.
Going to the paper itself we can observe that the CERN Antiproton Decelerator can deliver 10^7 antiprotons every 2 minutes. Remembering it previously took 10 weeks to capture 10^4 anti-atoms, I hope you forgive me for not agreeing that the antiproton generation is the source of important inefficiencies.
Now we can make a firecracker's worth of antimatter (by annihilation energy) in a mere two hundred thousand years of continuous production. Super cool stuff though, pun intended.
if produced in BIG enough quantities, very small reactors. As far as AM cannot be mined, but only produced at high price, currently it would matter only for deep space and bombs where we have RTG-s for deep space.

(You have to wait for civic applications of the newly discovered technologies for a while, but the "technology transfer" from CERN to practical applications has a few notable examples.)
The most realistic sci-fi engines are nuclear pulse engines where you ride the shockwaves of thousands of fusion bombs to reach a few percent of the speed of light. Those we could probably build right now if we were willing to spend the money. Replacing the fusion bombs with antimatter bombs would be a nice improvement for the basic design
Is there a way to slow down using fusion bombs? Even if you manage to bring thousands of fusion bombs with you? Sounds like this is only a sensible approach for sending probes, which will then zip by their target at huge speeds.
In all (realistic) interplanetary space travel - not to mention interstellar - the difference between the largest bomb/death ray anyone has ever experienced and a better drive, is purely a matter of where you aim it and when/how you throttle it up.
The most hilarious part of the expanse for instance is how they didn’t really use their actual drives as weapons even in CQB, which is quite a waste!
Not actually that different for rockets now, frankly, we just usually don’t operate direct nuclear fission/fusion drives right now for this very reason and our own sense of self preservation.
There certainly are plans on the drawing board!
It would take 23 grams of antimatter to produce the effect of a 1 megaton nuclear bomb, and the biggest factor stopping someone is both production of the matter itself (improving) and actual shielding technology (magnetic bottles good enough to effectively trap that much antimatter are huge and extremely energy consuming right now - much bigger than a fusion bomb of equivalent power).
Theoretically, it should be possible to store that much in a thermos bottle, however. We just need better superconductor technology.
