• Authors: Ghislain Fourny
• Abstract summary: We argue that a simple, albeit somewhat uncomfortable shift of viewpoint leads to a way out of the impossibility to extend the theory beyond indeterminism. The paradigm shift involves a non-trivial relaxation of the commonly accepted mathematical definition of free choice.

• Abstract: In this letter, we point to three widely accepted challenges that the quantum theory, quantum information, and quantum foundations communities are currently facing: indeterminism, the semantics of conditional probabilities, and the spooky action at a distance. We argue that these issues are fundamentally rooted in conflations commonly made between causal dependencies, counterfactual dependencies, and statistical dependencies. We argue that a simple, albeit somewhat uncomfortable shift of viewpoint leads to a way out of the impossibility to extend the theory beyond indeterminism, and towards the possibility that sound extensions of quantum theory, possibly even deterministic yet not super-deterministic, will emerge in the future. The paradigm shift, which we present here, involves a non-trivial relaxation of the commonly accepted mathematical definition of free choice, leading to non-Nashian free choice, more care with the choice of probabilistic notations, and more rigorous use of vocabulary related to causality, counterfactuals, and correlations, which are three concepts of a fundamentally different nature.

  We propose a hidden variable theory compatible with non-relativistic quantum electrodynamics. Our approach introduces logical variables to describe propositions about the occupation of stationary states. It successfully describes the essential properties of individual trials.

• Epistemic Boundaries and Quantum Uncertainty: What Local Observers Can (Not) Predict [0.0]
  We argue that post-quantum theories can offer a predictive advantage while conforming to the Born rule on average. We uncover a fascinating possibility: When the assumption of reliable intersubjectivity between different observers is violated, subjective predictive advantage can, in principle, exist. The findings reconcile us to quantum uncertainty as an aspect of limits on Nature's predictability.

  We argue in favour of taking Kolmogorov's measure-theoretic axiomatisation of probability as the starting point towards an axiomatisation of causality. Our proposed framework is rigorously grounded in measure theory, but it also sheds light on long-standing limitations of existing frameworks.

• Causal nonseparability and its implications for spatiotemporal relations [0.0]
  This work investigates the philosophical implications of causal nonseparability, especially for the notion oftemporal relations. A preliminary discussion will study the formal connection between quantum and causal nonseparability. It will be shown that, depending on the interpretative framework, causal nonseparability suggests some kind of indeterminacy oftemporal relations.

• Convexity and uncertainty in operational quantum foundations [0.0]
  The purpose of this thesis is to investigate fundamental aspects of uncertainty. We first try to reveal why in quantum theory similar bounds are often obtained for two types of uncertainty relations. Then we consider a broader expression of uncertainty in quantum theory called quantum incompatibility.

• Lack of Value Definiteness in Quantum Gravity [0.0]
  We show in both Loop Quantum Gravity and in String Theory, these observables are non-commuting ones. We propose to interpret these physical quantities as ontologically indeterminate -- i.e., indeterminate in a non-epistemic, mind-independent way. This result has two important consequences for current debates in philosophy of physics.

  We put forth a new theoretical framework for merging quantum information science and causal inference by exploiting entropic principles. We apply our proposed framework to an experimentally relevant scenario of identifying message senders on quantum noisy links. This approach can lay the foundations of identifying originators of malicious activity on future multi-node quantum networks.
