Information and measurement in generally covariant quantum theory
S. Jay Olson, Jonathan P. Dowling
abstract: Due to the absence of an external, classical time variable, the probabilistic
predictions of covariant quantum theory are ambiguous when multiple
measurements are considered. Here, we introduce an information theoretic
framework to the covariant formalism, and use it to interpret the measurement
process. We find that the time ordering of measurements emerges as an entropy
relationship in the state of the observers, giving unique probabilities for
multiple measurements. This approach suggests a new, fully self-contained
probability interpretation for generally covariant quantum physics, which makes
use of a quantum mechanical description of the observer, in contrast to
standard quantum mechanics which assumes an external, classical observer.
