Quantum causal models
Speaker(s): Jonathan Barrett
Abstract: From a brief discussion of how to generalise Reichenbach’s Principle of the Common Cause to the case of quantum systems, I will develop a formalism to describe any set of quantum systems that have specified causal relationships between them. This formalism is the nearest quantum analogue to the cl... read more

Infinite composite systems and cellular automata in operational probabilistic theories
Speaker(s): Paolo Perinotti
Abstract: Cellular automata are a central notion for the formulation of physical laws in an abstract information-theoretical scenario, and lead in recent years to the reconstruction of free relativistic quantum field theory. In this talk we extend the notion of a Quantum Cellular Automaton to general Operatio... read more

Local quantum operations and causality
Speaker(s): Robert Oeckl
Abstract: I give further details on a unification of the foundations of operational quantum theory with those of quantum field theory, coming out of a program that is also known as the positive formalism. I will discuss status and challenges of this program, focusing on the central new concept of local quantu... read more

Towards synthetic Euclidean quantum field theory
Speaker(s): Tobias Fritz
Abstract: In this status report on current work in progress, I will sketch a generalization of the temporal type theory introduced by Schultz and Spivak to a logic of space and spacetime. If one writes down a definition of probability space within this logic, one conjecturally obtains a notion whose semantics... read more

Almost quantum correlations violate the no-restriction hypothesis
Speaker(s): Ana Belen Sainz
Abstract: To identify which principles characterise quantum correlations, it is essential to understand in which sense this set of correlations differs from that of almost quantum correlations. We solve this problem by invoking the so-called no-restriction hypothesis, an explicit and natural axiom in many rec... read more

A device-independent approach to testing physical theories from finite data
Speaker(s): Yeong-Cherng Liang
Abstract: The device-independent approach to physics is one where conclusions are drawn directly and solely from the observed correlations between measurement outcomes. This operational approach to physics arose as a byproduct of Bell's seminal work to distinguish quantum correlations from the set of correlat... read more

Quantum axiomatics à la carte
Speaker(s): Alexander Wilce
Abstract: The past decade or so has produced a handful of derivations, or reconstructions, of finite-dimensional quantum mechanics from various packages of operational and/or information-theoretic principles. I will present a selection of these principles --- including symmetry postulates, dilational assump... read more

Quantum reference systems: Where foundations meets gravity
Speaker(s): Philipp Hoehn
Abstract: Quantum foundations and (quantum) gravity are usually considered independently. However, I will demonstrate by means of quantum reference systems how tools and perspectives from quantum gravity can help to solve problems in quantum foundations and, conversely, how quantum foundation perspectives can... read more

Observables and (no) time in quantum gravity
Speaker(s): Bianca Dittrich
Abstract: I will explain the special requirements that observables have to satisfy in quantum gravity and how this affects deeply the notion of time. I will furthermore explore how the search for observables in classical gravity can inform the construction of a quantum theory of gravity.
