Bell non-locality, Hardy’s paradox and hyperplane dependence

Published by on

Gordon N. Fleming Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” I argue, in section 4, that the ‘elements of reality’ of Hardy’s famous gedanken experiment can retain their Lorentz invariance, i.e., their frame independence, if one recognizes the hyperplane dependence of their localization. This requires avoiding the conflation of hyperplane dependence with frame dependence, which… Read more →

Is Any Theory Compatible With The Quantum Predictions Necessarily Nonlocal?

Published by on | 1 Response

Bernard d’Espagnat Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” Important advancements in scientific knowledge may, not infrequently, be looked at from several angles. Here, for investigating the question the article title defines, part of our attention shall have to be turned on the relationships of Bell’s theorem with the old, but still not fully cleared… Read more →

A possible definition of a Realistic Physics Theory

Published by on | 3 Responses

Nicolas Gisin (University of Geneva) Submitted to “90 Years of Quantum Mechanics” A definition of a Realistic Physics Theory is proposed based on the idea that, at all time, the set of physical properties possessed (at that time) by a system should unequivocally determine the probabilities of outcomes of all possible measurements. Full text

The roads not taken: empty waves, wavefunction collapse and protective measurement in quantum theory

Published by on

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 →

Entanglement, scaling, and the meaning of the wave function in protective measurement

Published by on

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 →

Precedence and freedom in quantum physics (Open Review Paper)

Published by on | 4 Responses

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 →
