Using humans to switch the settings in a Bell experiment
Speaker(s): Lucien Hardy
Abstract: I discuss how we might go about about performing a Bell experiment in which humans are used to decide the settings at each end. To get a sufficiently high rate of switching at both ends, I suggest an experiment over a distance of about 100km with 100 people at each end wearing EEG headsets, with the... read more

Bringing General Relativity into the Operational Probabilistic Framework
Speaker(s): Lucien Hardy
Abstract: I will discuss my work (in progress) to formulate General Relativity as an operational theory which includes probabilities and also agency (knob settings). The first step is to find a way to discuss operational elements of GR. For this I adapt an approach due to Westman and Sonego. I assert that all... read more

Operational structures and Natural Postulates for Quantum Theory
Speaker(s): Lucien Hardy
Abstract: In this talk we provide four postulates that are more natural than the usual postulates of QT.  The postulates require the predefinition of two integers, K and N, for a system. K is the number of probabilities that must be listed to specify the state.  N is the maximum number of st... read more

Operational structures as a foundation for probabilistic theories

Causality in quantum theory and beyond: towards a theory of quantum gravity

Abstract: The way we combine operators in quantum theory depends on the causal relationship involved. For spacelike separated spacetime regions we use the tensor product. For immediately sequential regions of spacetime we use the direct product. In the latter case we lose information – that is we cannot g... read more
