Well, it is possible that some physical systems can do more than quantum computers as currently conceived. However, I think it's better to reserve the term "quantum computers" to refer to "computers as deemed possible according to quantum mechanics" ... If Penrose and other radicals are right, then "quantum gravity computers" may be able to do stuff that quantum computers can't do ... which is physically sensible since quantum mechanics is known not to be a complete theory of the physical universe.... > > > As for your views on quantum probability...

Yes, I know that view of course, and I think it's wrong ... but, arguing that stuff on this list would be too much of a digression, as well as something I don't have time for tonight ;-) Will be fun to debate w/you someday though!! ben g ------------------------------------------- agi Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: https://www.listbox.com/member/?member_id=8660244&id_secret=114414975-3c8e69 Powered by Listbox: http://www.listbox.com
