Dear Friends,
I recommend the following paper for your comment:

The Computing Spacetime
Fotini Markopoulou
<http://arxiv.org/find/gr-qc/1/au:+Markopoulou_F/0/1/0/all/0/1>
(Submitted on 17 Jan 2012)
The idea that the Universe is a program in a giant quantum computer
is both fascinating and suffers from various problems. Nonetheless,
it can provide a unified picture of physics and this can be very
useful for the problem of Quantum Gravity where such a unification
is necessary. In previous work we proposed Quantum Graphity, a
simple way to model a dynamical spacetime as a quantum computation.
In this paper, we give an easily readable introduction to the idea
of the universe as a quantum computation, the problem of quantum
gravity, and the graphity models.
Onward!
Stephen
