Abstract quantum theory
Speaker(s): Robert Oeckl
Abstract: What is the essence of quantum theory? In the present talk I want to approach this question from a particular operationalist perspective. I take advantage of a recent convergence between operational approaches to quantum theory and axiomatic approaches to quantum field theory. Removing anything spec... read more

PIRSA:15050097  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Towards new foundations of quantum theory from first principles and from quantum field theory
Speaker(s): Robert Oeckl
Abstract: As is well known, time plays a special role in the standard formulation of quantum theory, bringing the latter into severe conflict with the principles of general relativity. This suggests the existence of a more fundamental and (as it turns out) covariant and timeless formulation of quantum theory.... read more

PIRSA:14110135  ( MP4 Medium Res , MP3 , PDF ) Which Format?
From locality and operationalism to classical and quantum theory?
Speaker(s): Robert Oeckl
Abstract: We present a first principles approach to a probabilistic description of nature based on two guiding principles: spacetime locality and operationalism. No notion of time or metric is assumed, neither any specific physical model. Remarkably, the emerging framework converges with the recently proposed... read more

A positive and local formalism for quantum theory
Speaker(s): Robert Oeckl
Abstract: The general boundary formulation (GBF) is an atemporal, but spacetime local formulation of quantum theory. Usually it is presented in terms of the amplitude formalism, which, in the presence of a background time, recovers the pure state formalism of the standard f... read more

PIRSA:09010002  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Against commutators
Speaker(s): Robert Oeckl
Abstract: The essential ingredients of a quantum theory are usually a Hilbert space of states and an algebra of operators encoding observables. The mathematical operations available with these structures translate fairly well into physical operations (preparation, measurement etc.) in a non-relativistic world... read more
