Hello.(adsbygoogle = window.adsbygoogle || []).push({});

I've got childish question.

I know that quantum computers are more effective than classical ones

in solving some problems. Naturally, a thought have come to me: are

there computers which are more effective than quantum ones, maybe

some "Superstring" computers? And maybe there are computers which

are more effective than Superstring computers? And so foth, ad infinitum.

I tried to search on the Internet for "superstring computers" with no result.

Accidentally on the http://www.theory.caltech.edu/people/preskill/" [Broken]

I've found http://www.theory.caltech.edu/~preskill/talks/berkeley_jp_may02.pdf" [Broken].

Here are Preskill's words from this talk:

"Can a quantum computer simulate M theory efficiently? Perhaps not,

because of M-theory inherent nonlocality. E.g., a quantum system

described by M-theory may have no natural tensor product

decomposition into smaller systems. Thus, M-theory may be a more

powerful computational model." :surprised

So I decided to ask you, what do you think about all this?
