I have to close this catch-all question review thread as a highly inadvisable activity.
First, if a particular question (or a larger subject space) becomes troublesome in actual practice, the merits of that topic should be raised and discussed in its own thread. Questions can and do get closed by those with that ability/reputation, but to make any question linked here subject to an ongoing pseudo meta poll ("vote up if you agree … this should be on another site") is not how this site is supposed to work.
Regarding the issue of whether cross-site questions should be moved elsewhere, please read
Respect the community – your own, and others’
Folks join this site because they have an interest in "quantum computing". You should uphold that as your scope comprehensively. A question that might also fit elsewhere does not make it off topic for this site. Please be careful about slicing this site up into a patchwork of topics trying to avoid pieces that might also fit on another site.
Unless a question or topic space has been deemed off topic on this site explicitly, we have no cause to remove someone's content for another site, along with the reputation and ownership that goes with it.
A quick note about moving questions to other sites —
Migrations have largely fallen out of favor as a means of moving new questions just asked. Migrations were intended to be used where there was significant content (answers) to be moved to another site when the scope of a site changes. But migrations have too many side effects to use them to routinely move new questions. They tend to make a mess of things (e.g. orphaned content becomes anonymous, improper tags, out of place comments, mismatched voting, ignoring any community guidelines, automatic dupe checks are skipped, etc), so migrations should not be used simply to move a question asked on the wrong site. When there is little content to save, the author should simply flag or delete the question, and re-ask their question in the context of the correct site.
