The term "quantum computer" does not mean an object that uses quantum mechanics, it would be pretty silly if it did as every object in the universe does, it means an object that uses quantum algorithms and quantum logic to process information. Until Feynman raised the possibility in the 1980s nobody had even thought about such a thing and it's only been since Shor's factoring work in 1994 that it has looked like they might actually be practical someday. But I repeat what I said before, there is not one speck of evidence that the human brain uses any sort of quantum algorithm in its logic or memory processing.</font><div class="gmail_default"><font face="arial, helvetica, sans-serif"> </font></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;display:inline"></div><font size="4">Yes<div class="gmail_default" style="font-family:arial,helvetica,sans-serif;display:inline"> </div>Penrose and Hameroff<div class="gmail_default" style="font-family:arial,helvetica,sans-serif;display:inline"> </div>had a theory that<div class="gmail_default" style="font-family:arial,helvetica,sans-serif;display:inline"> </div>electrons inside<div class="gmail_default" style="font-family:arial,helvetica,sans-serif;display:inline"> </div>the<div class="gmail_default" style="font-family:arial,helvetica,sans-serif;display:inline"> </div>microtubules in neurons would somehow get entangled and then somehow process information,<div class="gmail_default" style="font-family:arial,helvetica,sans-serif;display:inline"> </div>but they were extremely vague on how it would all work and there is zero evidence<div class="gmail_default" style="font-family:arial,helvetica,sans-serif;display:inline"> </div>that they're actually right.
