Experimental implementation of quantum-coherent mixtures of causal relations
Abstract: Understanding the causal influences that hold among the parts of a system is critical both to explaining that system's natural behaviour and to controlling it through targeted interventions. In a quantum world, understanding causal relations is equally important, but the set of possibilities is far ... read more

Cause and Effect in a Quantum World
Speaker(s): Robert Spekkens

PIRSA:15050081  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Nonclassicality as the failure of noncontextuality
Speaker(s): Robert Spekkens
Abstract: To make precise the sense in which nature fails to respect classical physics, one requires a formal notion of "classicality". Ideally, such a notion should be defined operationally, so that it can be subjected to a direct experimental test, and it should be applicable in a wide variety of experiment... read more

Can Quantum Correlations be Explained Causally?
Speaker(s): Robert Spekkens
Abstract: There is a strong correlation between the sun rising and the rooster crowing, but to say that the one causes the other is to say more. In particular, it says that making the rooster crow early will not precipitate an early dawn, whereas making the sun rise early (for instance, by moving the rooster ... read more

The invasion of physics by information theory
Speaker(s): Robert Spekkens
Abstract: When we think of a revolution in physics, we usually think of a physical theory that manages to overthrow its predecessor. There is another kind of revolution, however, that typically happens more slowly but that is often the key to achieving the first sort: it is the discovery of a novel perspectiv... read more

Are superselection rules fundamental?
Speaker(s): Robert Spekkens
Abstract: Superselection rules in quantum theory assert the impossibility of preparing coherent superpositions of certain conserved quantities. For instance, it is commonly presumed that there is a superselection rule for charge and for baryon number, as well as a "univalence superselection rule" forbidding a... read more

Why I Am Not a Psi-ontologist
Speaker(s): Robert Spekkens
Abstract: The distinction between a realist interpretation of quantum theory that is psi-ontic and one that is psi-epistemic is whether or not a difference in the quantum state necessarily implies a difference in the underlying ontic state. Psi-ontologists believe that it does, psi-epistemicists that it does ... read more

Formulating Quantum Theory as a Causally Neutral Theory of Bayesian Inference
Speaker(s): Robert Spekkens
Abstract: Quantum theory can be thought of as a noncommutative generalization of Bayesian probability theory, but for the analogy to be convincing, it should be possible to describe inferences among quantum systems in a manner that is independent of the causal relationship between those systems.

The status of determinism in noncontextual models of quantum theory

Abstract: In an ontological model of quantum theory that is Bell-local, one can assume without loss of generality that the outcomes of measurements are determined deterministically by the ontic states (i.e. the values of the local hidden variables).

Specker's parable of the overprotective seer: Implications for Contextuality, Nonlocality and Complementarity
Speaker(s): Robert Spekkens
Abstract: I revisit an example of stronger-than-quantum correlations that was discovered by Ernst Specker in 1960. The example was introduced as a parable wherein an over-protective seer sets a simple prediction task to his daughter's suitors. The challenge cannot be met because the seer asks the suitors for ... read more

The Strange Quantum: What does it mean and how can we use it?
Speaker(s): Robert Spekkens
Abstract: Put two physicists in a room and ask them to talk about the interpretation of quantum mechanics. This is a recipe for disagreement; the mysteries of quantum theory run so deep that it’s hard to find any interpretive claims that are immune to controversy. Therefore, when thinking about quantum theo... read more

Why the quantum? Insights from classical theories with a statistical restriction
Speaker(s): Robert Spekkens
Abstract: It is common to assert that the discovery of quantum theory overthrew our classical conception of nature. But what, precisely, was overthrown? Providing a rigorous answer to this question is of practical concern, as it helps to identify quantum technologies that outperform their classical counterpar... read more

The resource theory of quantum reference frames: manipulations and monotones
Speaker(s): Robert Spekkens
Abstract: Every restriction on quantum operations defines a resource theory, determining how quantum states that cannot be prepared under the restriction may be manipulated and used to circumvent the restriction. A superselection rule is a restriction that arises through the lack of a classical reference fr... read more

The Strange Quantum: What does it mean and how can we use it? ISSYP Keynote Session
Speaker(s): Robert Spekkens
Abstract: In this talk, I describe some very simple but significant phenomena predicted by quantum theory. These are described simply in terms of what is observed in the laboratory, without making any presumptions about what sort of microscopic picture of reality might account for these observations. With th... read more

Liouville mechanics with an epistemic restriction and Bohr's response to EPR
Speaker(s): Robert Spekkens
Abstract: I will discuss a toy theory that reproduces a wide variety of qualitative features of quantum theory for degrees of freedom that are continuous. The ontology of the theory is that of classical particle mechanics, but it is assumed that there is a constraint on the amount of knowledge that an observe... read more
