Interpretations of Quantum Mechanics
Speaker(s): Robert Spekkens
Abstract: Just as there is a
difference between knowing how to *drive* a car and understanding its
functioning well enough to fix it when it breaks down, so too is there a
difference between knowing how to *use* quantum theory to make
predictions and understanding... 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. In particular... read more

The status of determinism in noncontextual models of quantum theory
Speaker(s): Robert Spekkens
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). The question I address in this talk is whether such determin... read more

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

Lecture Series presented by KPMG - Quantum Foundations: From Plato's Cave to Bertlmann's Socks
Speaker(s): Robert Spekkens
Abstract: The mysteries of quantum theory run deep. Despite 80 years of research, there is still no consensus on its interpretation. This talk will explore some of the important issues in the foundations of quantum theory, from the idea that we have only a limited knowledge of a deeper reality, like the priso... read more

Quantum analogues of Bayes' theorem, sufficient statistics and the pooling problem
Speaker(s): Robert Spekkens
Abstract: The notion of a conditional probability is critical for Bayesian reasoning. Bayes’ theorem, the engine of inference, concerns the inversion of conditional probabilities. Also critical are the concepts of conditional independence and sufficient statistics. The conditional density operator i... 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.

Liouville mechanics with an epistemic restriction and Bohr's response to EPR
