An Epistemic View of Quantum Communication [article]

Subhash Kak
2016 arXiv   pre-print
The notion of information obtained in such a communication is a property associated with the observers and while dependent on the nature of the physical system its fundamental basis is epistemic.  ...  This paper presents an epistemological perspective on quantum communication between parties that highlights the choices that must be made in order to send and obtain information.  ...  Next we examine the question of information in classical and quantum settings highlighting how its definition in the framework of ensembles requires an epistemic basis.  ...

On the Classification Between $$\psi$$-Ontic and $$\psi$$-Epistemic Ontological Models

Andrea Oldofredi, Cristian López

In particular, we will show that, since in the statistical interpretation ontic states describe ensembles rather than individuals, such a view cannot be considered ψ -epistemic.  ...  Moreover, they claimed that Einstein-who was a supporter of the statistical interpretation of quantum mechanics-endorsed an epistemic view of ψ .  ...  Therefore, as a simple logical consequence of the authors' classification, the ensemble view must be a -incomplete model which is also -epistemic.  ...

Comprehensive Multi-Agent Epistemic Planning

Francesco Fabiano
2021 Electronic Proceedings in Theoretical Computer Science  
In particular, we aim to achieve such goal by defining a new action-based language for multi-agent epistemic planning and to implement an epistemic planner based on it.  ...  In particular, this manuscript is focused on a specialized kind of planning known as Multi-agent Epistemic Planning (MEP).  ...  Epistemic Logic Dynamic Epistemic Logic is, clearly, connected to epistemic logic: that is the logic that allows to reason on the knowledge/belief of agents in static domains.  ...

The wave-function as a true ensemble [article]

J.R. Hance, S. Hossenfelder
2021 arXiv   pre-print
We argue that the ψ-ontic/epistemic distinction fails to properly identify ensemble interpretations and propose a more useful definition.  ...  In quantum mechanics, the wave-function only predicts probabilities of measurement outcomes, not individual outcomes.  ...  DIFFERENCE BETWEEN ψ-ENSEMBLE AND ψ-EPISTEMIC The introduction of the ψ-ensemble in the previous section sounds superficially very similar to the definition of a ψepistemic model introduced by Harrigan  ...

E-PDDL: A Standardized Way of Defining Epistemic Planning Problems [article]

Francesco Fabiano, Biplav Srivastava, Jonathan Lenchner, Lior Horesh, Francesca Rossi, Marianna Bergamaschi Ganapini
2021 arXiv   pre-print
This work is also useful in building more general epistemic planning environments where we envision a meta-cognitive module that takes a planning problem in E-PDDL, identifies and assesses some of its  ...  Epistemic Planning (EP) refers to an automated planning setting where the agent reasons in the space of knowledge states and tries to find a plan to reach a desirable state from the current state.  ...  This means that if the initial conditions do not comply with a finitary S5 logic the planners that construct the initial epistemic state from the given specification may not work.  ...

Testing for ontological errors in probabilistic forecasting models of natural systems

W. Marzocchi, T. H. Jordan
2014 Proceedings of the National Academy of Sciences of the United States of America  
Probabilistic forecasting models describe the aleatory variability of natural systems as well as our epistemic uncertainty about how the systems work.  ...  Testing a model against observations exposes ontological errors in the representation of a system and its uncertainties.  ...  Therefore, in common practice, the model ensemble {H m } is organized as branches of a logic tree, and the branch weights {π m }, which may depend on the hazard level x, are assigned according to expert  ...

Ontological Models in Quantum Mechanics: What do they tell us? [article]

Leslie Ballentine
2014 arXiv   pre-print
"Maximally ψ-epistemic" is shown to be equivalent to the conjunction of two other conditions, each of which can be realized in Hilbert spaces of arbitrary dimension, but which cannot occur together for  ...  A new condition, called "functionally ψ-epistemic", is introduced, which, were it to be excluded, would signal the exclusion of epistemic interpretations.  ...  But the case of ψ-ontic-supplemented also yields an ensemble description, so an ensemble interpretation can be either epistemic or ontic.  ...
