As someone who started off in "quantum" in similar conditions around the same time, but decided to stay on the academic researcher track:

A great deal of the recent progress has been on honing, parallelizing, and automating the same processes one used to do by hand/at small scale in 2013. You'll probably instantly recognize most of the things going on in the lab, and could become productive on a short schedule.

However, I'd be wary of the medium-term prospects of the field: The discord between the perceived and actual capabilities of the hardware remains as big as ever. You could consider re-entering the field if you're happy contributing to incremental technological advances relevant to other researchers. Progress with meaningful societal or economic impact is probably much further off.
