Correlations all the way Down?
Speaker(s): Dean Rickles
Abstract: I give a review and assessment of relational approaches to quantum theory – that is, approaches that view QM “as an account of the way distinct physical systems affect each other when they interact – and not the way physical systems ‘are’”.... read more

Probabilities from Quantum States, or Quantum States from Probabilities?
Speaker(s): Howard Barnum
Abstract: I will consider various attempts to derive the quantum probabilities from the HIlbert space formalism within the many-worlds interpretation, and argue that they either fail, or depend on tacit probabilistic assumptions. The main problem with the project is that it is difficult to understand what the... read more

Quantum Theory from Complementarity, and its Implications
Speaker(s): Philip Goyal
Abstract: Complex numbers are an intrinsic part of the mathematical formalism of quantum theory, and are perhaps its most mysterious feature. In this talk, we show how it is possible to derive the complex nature of the quantum formalism directly from the assumption that a pair of real numbers is associated wi... read more

Mapping classical fields to quantum states
Speaker(s): Kenneth Wharton
Abstract: Abstract: Efforts to extrapolate non-relativistic (NR) quantum mechanics to a covariant framework encounter well-known problems, implying that an alternate view of quantum states might be more compatible with relativity. This talk will reverse the usual extrapolation, and examine the NR limit of a r... read more

What does relativity tells us about quantum theory?
Speaker(s): Daniel Terno
Abstract: Spacelike separated classical interventions make us to rethink what is quantum and what is classical. Quantum Lorentz transformations show that identification of subsystems is a tricky business, ditto entropy, entanglement and thermodynamic quantities. Resolution of information loss problem in black... read more
