Direct experimental reconstruction of the Bloch sphere
Abstract: The scientific journey from the first hints of quantum behaviour to the Bloch sphere in your textbook was a long and tortuous one. But using some of the technological and conceptual fruits of that journey, we show that an experiment can manifest the Bloch sphere via an analysis that doesn't require ... read more

Beyond local causality: causation and correlation after Bell
Speaker(s): Matthew Pusey
Abstract: There is now a remarkable mathematical theory of causation. But applying this theory to a Bell scenario implies the Bell inequalities, which are violated in experiment. We alleviate this tension by translating the basic definitions of the theory into the framework of generalised probabilistic theori... read more

What's an unknown POVM, and what does a two qubit state look like?
Speaker(s): Matthew Pusey
Abstract: If probabilities represent knowledge, what is an "unknown probability"? De Finetti's theorem licenses the view that it is simply a convenient metaphor for a certain class of knowledge about a series of events. There are quantum versions for "unknown states" and "unknown channels". I will explai... read more
