Thanks—you’re right. I have seen “pure state” referring to a basis vector (e.g. in quantum computation), but in QTD your definition is definitely correct. I don’t like the term “pointer variable”—is there a different notation you like?
I’d prefer “basis we just so happen to be measuring in”. Or “measurement basis” for short.
You could use “pointer variable”, but this would commit you to writing several more paragraphs to unpack what it means (which I encourage you to do, maybe in a later post).
