The Quantum Mechanical Frame of
Reference
Andrew Soltau
Abstract: Everett demonstrates the appearance of collapse, within the
context of the unitary linear dynamics. However, he does not state
clearly how observers are to have determinate measurement records,
hence 50 years of debate. This, however, is inherent. He defines the
observer as the record of observations, which, naturally, is the record
of correlations established with the physical environment. As in
Rovellis Relational Quantum Mechanics , the correlations record is
the sole determinant of the effective physical environment, here the
quantum mechanical frame of reference: due to multiple realisation of
the functional identity of the observer, the physical environment is a
simultaneity of all the physical environments in which it is
instantiated, a universe superposition, in which only the environment
correlated with the observer by observations is determinate. This
effects a discrete and idiosyncratic physical environment for each
version of an observer, in which determinate measurement records are
recorded. Quantum mechanics is on this view fully relational,
demonstrated as not only viable but necessary by Rovelli Laudisa.
The quantum mechanical frame of reference is Everetts Relative
State, and on Tegmarks inside view, the time evolution follows the
standard von NeumannDirac formulation. Thus observers get
precisely the measurement records predicted by the standard
formulation, but since objectively there is only the appearance of
collapse, there is neither a measurement problem nor a disparity
with relativity. The linear dynamics and the collapse dynamics are
directly experienced, as the passage of time and the making of
observations, respectively.
