From time-reversal symmetry to quantum Bayes' rules
Arthur J. Parzygnat, James Fullwood
Bayes' rule is one of the simplest yet most profound, ubiquitous, and far-reaching results of classical probability theo…

Axioms for retrodiction: achieving time-reversal symmetry with a prior
Arthur J. Parzygnat, Francesco Buscemi
We propose a category-theoretic definition of retrodiction and use it to exhibit a time-reversal symmetry for all quantum channels. We do this by introducing retrodiction families…

On quantum states over time
James Fullwood, Arthur J. Parzygnat
In 2017, D. Horsman, C. Heunen, M. Pusey, J. Barrett, and R. Spekkens proved that there is no physically reasonable assignment that takes a quantum channel and an initial state and…
