It was published in "Scientific Reports", a known low-quality journal. They are not necessary predatory like some of the truly bad journals, e.g., work in this journal still is supposed to pass the "not a low effort triviality and not obviously wrong" check and there are even some really cool things published in this journal. However, I generally take publications in this journal with a significant grain of salt.

Also, just FYI, "Scientific Reports" is not in a specific subfield -- I have published on quantum computing in this journal. That is not too strange, there are plenty of "generalist" journals that are good, but I thought it could still be useful context to know.
