Conditional Probability Spaces and the Structure of Agreement
Erya Yang, Adam Brandenburger
We use the machinery of a conditional probability space (Rényi, 1955) to obtain an Agreement Theorem (Aumann, 1976) under general conditions. A conditional probability space (CPS)…
Axiomatization of Rényi Entropy on Quantum Phase Space
Adam Brandenburger, Pierfrancesco La Mura
Phase-space versions of quantum mechanics -- from Wigner's original distribution to modern discrete-qudit constructions -- represent some states with negative quasi-probabilities.…
Classical Simulation of Non-Classical Systems: A Large Deviation Analysis
Adam Brandenburger, Pierfrancesco La Mura
Any quasi-probability representation of a no-signaling system -- including quantum systems -- can be simulated via a purely classical scheme by allowing signed events and a cancell…
Delayed Arrow-of-Time Detection in Signed Laplacian Dynamics
Adam Brandenburger, Pierfrancesco La Mura
We study how rapidly the direction of time becomes operationally detectable from mesoscopic data when state-weights may be positive or negative. In contrast with classical Markov p…
