<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have read this paper, but it seems to me that the
word 'idealization' has a key place in it. Thus, the statement that 'quantum
mechanics is about the structure of information' begs the question of what
information is being discussed. Is it not conceivable, in the 'macroworld', that
the elements of the processes of energy transfer/transformation involved in
information do not commute and require a non-Boolean algebra?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I thus am unable, given my lack of knowledge of
quantum mechanics, to see the implications of the paper for the 'structure of
information in a genuinely partly deterministic world' such as the one (I
think) we live in.' If there are such implications, I would be sincerely
interested in knowing them. If there are no such implications, the paper gives a
useful picture of the cut. </FONT></DIV>

<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; BACKGROUND: white; COLOR: black; FONT-FAMILY: 'Arial','sans-serif'">The
aim of this paper is to consider the consequences of an information-theoretic
interpretation of quantum mechanics for the measurement problem. The
motivating idea of the interpretation is that the relation between quantum
mechanics and the structure of information is analogous to the relation
between special relativity and the structure of space-time. Insofar as quantum
mechanics deals with a class of probabilistic correlations that includes
correlations structurally different from classical correlations, the theory is
about the structure of information: the possibilities for representing,
manipulating, and communicating information in a genuinely indeterministic
quantum world in which measurement outcomes are intrinsically random are
different than we thought. Part of the measurement problem is deflated as a
pseudo-problem on this view, and the theory has the resources to deal with the
remaining part, given certain idealizations in the treatment of
macrosystems.<o:p></o:p></SPAN></P>
