Confusing Ontic and Epistemic Causes Trouble in Classical Physics Too
Speaker(s): N. David Mermin
Abstract: The subject of this conference is the Quantum State --- what the hell it is. A central issue is whether quantum states describe reality (the ontic view) or an agent's knowledge of reality (the epistemic view). Advocates of the epistemic view maintain that many quantum puzzles and conundra are artifa... read more

Does knowing my lambda mean knowing my psi?
Speaker(s): Terry Rudolph
Abstract: All known hidden variable theories that completely reproduce all quantum predictions share the feature that they add some information to the quantum state "psi". That is, if one knew the "state of reality" given by the hidden variable(s) "lambda"... read more

What are the costs of dealing with ";states of reality" in quantum theory?
Speaker(s): Caslav Brukner
Abstract: Bell and experimental tests of his inequality showed that it is impossible to explain all of the predictions of quantum mechanics using a theory which satisfies the basic concepts of locality and realism, but which (if not both) is violated is still an open question. As it seems impossible to resolv... read more

A Pilot Wave(s) Theory of Exclusively Local Beables
Speaker(s): Travis Norsen
Abstract: After reframing the question of the status of the quantum state in terms of J.S. Bell's "beables", I will sketch out a new theory which -- though nonlocal in the sense required by Bell's theorem -- posits exclusively local beables. This is a theory, in particular, in which the quan... read more

Reconciling the ontic and epistemic views in quantum contextuality
Speaker(s): Brian La Cour
Abstract: The classic debate between Einstein and Bohr over a realistic interpretation of quantum mechanics can be cast in terms of the measurement problem: Is there an underlying ontic state prior to measurement which maps deterministically to the measured outcome? According to the Kochen-Specker theorem... read more
