Entropy for theories with indefinite causal structure

Markes, Sonia, Hardy, Lucien

Understand

Entropy is a concept that has traditionally been reliant on a definite notion of causality.

However, without a definite notion of causality, the concept of entropy is not all lost.
Indefinite causal structure results from combining probabilistic predictions and dynamical space-time.
Combining the probabilistic nature of quantum theory and dynamical treatment space-time from general relativity is an approach to the problem of quantum gravity.
