Contextuality, Fine-tuning and Teleological Explanation
Emily Adlam - Chapman University
In this talk I will assess various proposals for the source of the intuition that there is something problematic about contextuality, and argue that contextuality is best thought of in terms of fine-tuning. I will suggest that as with other fine-tuning problems in quantum mechanics, this behaviour… -
Possibility of causal loops without superluminal signalling -- a general framework
Vilasini Venkatesh - University of York
Causality is fundamental to science, but it appears in several different forms. One is relativistic causality, which is tied to a space-time structure and forbids signalling outside the future. On the other hand, causality can be defined operationally using causal models by considering the flow of… -
Applied QBism and its Potential
John Debrota - University of New Mexico
The Quantum Bayesian, or QBist, interpretation regards the quantum formalism to be a tool that a single agent may adopt to help manage their expectations for the consequences of their actions. In other words, quantum theory is an addition to decision theory, and its shape, we hope, can teach us… -
Quantum networks theory
Pablo Arrighi - Université Grenoble Alpes
The formalism of quantum theory over discrete systems is extended in two significant ways. First, tensors and traceouts are generalized, so that systems can be partitioned according to almost arbitrary logical predicates. Second, quantum evolutions are generalized to act over network configurations… -
Detecting nonclassicality in restricted general probabilistic theories
Leevi Leppajarvi - University of Turku
The formalism of general probabilistic theories provides a universal paradigm that is suitable for describing various physical systems including classical and quantum ones as particular cases. Contrary to the often assumed no-restriction hypothesis, the set of accessible measurements within a given… -
Exploring quantum correlations in causal networks
George Moreno - Universidade Federal do Rio Grande do Norte
Bell’s theorem is typically understood as proof that quantum theory is incompatible with local hidden variable (LHV) models. In recent years, however, LHV models have been recognized as a particular and simple case of much more general causal networks that can give rise to new and stronger forms of… -
The Page-Wootters formalism: Where are we now?
Alexander Smith - Saint Anselm College
General relativity does not distinguish a preferred reference frame, and conservatively one ought to expect that its quantization does not necessitate such background structure. However, this desire stands in contrast to orthodox formulations of quantum theory which rely on a background time… -
The Entropic Dynamics approach to Quantum Mechanics
Ariel Caticha - State University of New York (SUNY)
Entropic Dynamics (ED) is a framework in which Quantum Mechanics is derived as an application of entropic methods of inference. In ED the dynamics of the probability distribution is driven by entropy subject to constraints that are codified into a quantity later identified as the phase of the wave… -
Quantum Theory needs complex numbers
Marc-Olivier Renou - ICFO - Institute of Photonic Sciences
While complex numbers are essential in mathematics, they are not needed to describe physical experiments, expressed in terms of probabilities, hence real numbers. Physics however aims to explain, rather than describe, experiments through theories. While most theories of physics are based on real… -

Making sense of semiclassical gravity
André Großardt - Friedrich Schiller University Jena
In absence of both experimental evidence for and a fully understood theory of quantum gravity, the possibility that gravity might be fundamentally classical presents an option to be considered. Such a semiclassical theory also bears the potential to be part of an objective explanation for the… -
Beyond Chance and Credence
Wayne Myrvold - Western University
This talk is about how to think about probabilistic reasoning and its use in physics. It has become commonplace, in the literature on the foundations of probability, to note that the word “probability” has been used in at least two distinct senses: an objective, physical sense (often called…
