Where does “QD” come from?

I can't write an accurate etymology sentence for this chain because the meaning of the English headword QD is unknown, and the connection between "QD" and Latin "quaque" isn't established by the information provided. An etymology requires tracing how a word's form and meaning developed across languages, but without knowing what QD means or how it relates to the Latin source, I cannot responsibly create a sentence that would misrepresent the actual linguistic relationship. If you can provide the meaning of QD or clarify the etymological connection, I'd be happy to write the sentence.

QD (English): once per day; Initialism of quantum dot
