Title: Theory-Independent Realism
Authors: D. M. Fucci, R. M. Angelo,
Abstract summary: We use a framework of generalized probabilistic theories to expand the notion of realism for a theory-independent context. We propose quantifiers for the realism of arbitrary physical properties given a particular state of a generic physical theory. These theory-independent quantifiers are then employed in quantum mechanics and we investigate their relation with another well-established irrealism measure.

Abstract: The distinctive features of quantum mechanics, which set it apart from other physical theories, challenge our notions of realism. Recovering realism from purely philosophical grounds, a quantitative and operational criterion was proposed in the past, but solely for the context of quantum mechanics. We use a framework of generalized probabilistic theories to expand the notion of realism for a theory-independent context, providing a criterion uniquely based on the probabilities assigned to measurement outcomes. More so, using robustness and the Kullback-Leibler divergence, we propose quantifiers for the realism of arbitrary physical properties given a particular state of a generic physical theory. These theory-independent quantifiers are then employed in quantum mechanics and we investigate their relation with another well-established irrealism measure.

Testing trajectory-based determinism via time probability distributions [44.99833362998488]
Bohmian mechanics (BM) has inherited more predictive power than quantum mechanics (QM) We introduce a prescription for constructing a flight-time probability distribution within generic trajectory-equipped theories. We derive probability distributions that are unreachable by QM.

Relaxation of first-class constraints and the quantization of gauge theories: from "matter without matter" to the reappearance of time in quantum gravity [72.27323884094953]
We make a conceptual overview of an approach to the initial-value problem in canonical gauge theories. We stress how the first-class phase-space constraints may be relaxed if we interpret them as fixing the values of new degrees of freedom.

A refinement of the argument of local realism versus quantum mechanics by algorithmic randomness [0.0]
In quantum mechanics, the notion of probability plays a crucial role. In modern mathematics, probability theory means nothing other than measure theory. We present a refinement of the Born rule, called the principle of typicality, for specifying the property of results of measurements in an operational way.

A Measure-Theoretic Axiomatisation of Causality [55.6970314129444]
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.

Potentiality realism: A realistic and indeterministic physics based on propensities [0.0]
We discuss our specific interpretation of propensities, that require them to depart from being probabilities at the formal level. This view helps reconcile classical and quantum physics by showing that most of the conceptual problems that are customarily taken to be unique issues of the latter are actually in common to all indeterministic physical theories.

Quantum Theory Needs (And Probably Has) Real Reduction [0.0]
It appears that for quantum theory to be viable in a realist sense, it must possess genuine, physical non-unitarity. Penrose's theory of gravitation-induced collapse and the Transactional Interpretation are discussed.

Quantum realism: axiomatization and quantification [77.34726150561087]
We build an axiomatization for quantum realism -- a notion of realism compatible with quantum theory. We explicitly construct some classes of entropic quantifiers that are shown to satisfy almost all of the proposed axioms.

Gentle Measurement as a Principle of Quantum Theory [9.137554315375919]
We propose the gentle measurement principle (GMP) as one of the principles at the foundation of quantum mechanics. We show, within the framework of general probabilistic theories, that GMP imposes strong restrictions on the law of physics.

Unscrambling the omelette of causation and inference: The framework of causal-inferential theories [0.0]
We introduce the notion of a causal-inferential theory using a process-theoretic formalism. Recasting the notions of operational and realist theories in this mold clarifies what a realist account of an experiment offers beyond an operational account. We argue that if one can identify axioms for a realist causal-inferential theory such that the notions of causation and inference can differ from their conventional (classical) interpretations, then one has the means of defining an intrinsically quantum notion of realism.
