I've seen this bouncing around since the early 90s, with New Agey people like Danah Zohar, and probably predates even that. There never seemed to be a whole lot to it; not much more than "well, consciousness is weird, and quantum is weird, therefore consciousness is quantum". Or maybe "well, quantum is trendy, and I'd like to make a buck, therefore..."

FWIW the only place I EVER see the phrase "citation needed" is on HN. That's not a good or a bad thing: it's simply an observation.
