In my haste in a recent question I accidentally created the
w-state tag - I didn't realize that it had not already been created. Apparently there is similarly no
ghz-state tag (although there is a
A quick search of the site notes that there are a good number (I would guess at least thirty) questions wherein the W-state is fundamental to the question and is not incidental to the answer. Further there are maybe a similar number of such questions about GHZ states. Such questions may be a bit better than, say,
faster-than-light (while not disparaging that tag in particular), which has six questions total.
Should there be such tags? If so, what is the best time to touch posts to retag so that they minimize impact to the front page? Would they provide any value - for example, would Google use the tags in any manner?
I've tried to do various global updates for some questions on the weekend (e.g., Josza -> Jozsa and q-bit -> qubit), when the volume appears lowest, but I probably inadvertently move some good questions and answers further down the front page.
Tag creation and management/retagging appears to be high-maintenance activities. I am not sure if there's a way to retag a post that doesn't otherwise touch it to move to the front page.
