Peter Holland, University of Oxford In this contribution we shall be concerned with two classes of interpretations of quantum mechanics: the epistemological (the historically dominant view) and the ontological. The first views the wavefunction as just a repository of (statistical) information on a physical system. The other treats the wavefunction primarily as an element of physical reality, whilst generally retaining... Read more →
Maximilian Schlosshauer and Tangereen V. B. Claringbold (University of Portland) We examine the entanglement and state disturbance arising in a protective measurement and argue that these inescapable effects doom the claim that protective measurement establishes the reality of the wave function. An additional challenge to this claim results from the exponential number of protective measurements required to reconstruct multi-qubit states.... Read more →

Lee Smolin (Perimeter Institute for Theoretical Physics) A new interpretation of quantum mechanics is proposed according to which precedence, freedom and novelty play central roles. This is based on a modification of the postulates for quantum theory given by Masanes and Muller. We argue that quantum mechanics is uniquely characterized as the probabilistic theory in which individual systems have maximal... Read more →

Roman Jackiw Department of Physics, Massachusetts Institute of Technology John Bell and I met and became acquainted in 1967, when I went to CERN for a year-long research visit, soon after finishing my doctoral studies a Cornell. At that time, particle physics theory was dominated, as it happens from time-to-time, by a single idea; there was broad agreement among theorists... Read more →

During recent years, there is increasing interest in the ontological status and meaning of the wave function, and it seems that there is even a shift in research focus from the measurement problem to the problem of interpreting the wave function. This motivates us to organize an online workshop on the meaning of the wave function. The workshop aims to... Read more →
Proud to support the new journal! Here is my first submission: note on Leggett-Garg 4. Abstract: In this paper we first analyse Leggett and Garg's argument to the effect that macroscopic realism contradicts quantum mechanics. After making explicit all the assumptions in Leggett and Garg's reasoning, we argue against the plausibility of their auxiliary assumption of non-invasive measurability, using Bell's construction...
