Leggett-Garg Inequalities, Pilot Waves and Contextuality (Open Review Paper)

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...

IJQF website is mobile ready

Our IJQF website has been upgraded to improve its speed and user experience. Moreover, the site is mobile ready. You can now visit the site with an iPad or a smart phone. For example, mobile visitors are able to navigate through the website and browse the Latest Papers on Quantum Foundations. Thanks to Frederick Townes and Sami Keijonen for their wonderful work!

The PBR theorem seen from the eyes of a Bohmian

The aim of this paper is to present an analysis of the new theorem by Pusey, Barrett and Rudolph (PBR) concerning ontic and epistemic hidden variables in quantum mechanics [Nature Phys. 8, 476 (2012)]. This is a kind of review and defense of my previous critical analysis done in the context of Bohmian mechanics. This is also the occasion for me to review some of... Read more →

IJQF launches preprint service

Although IJQF has a feed engine to search Latest Papers on Quantum Foundations worldwide and updates the list of papers daily, it is more convenient and helpful for members to upload their preprints and papers on quantum foundations in their IJQF blogs. Once these papers have been posted in the blogs, they are immediately visible to all members, and more importantly, other members can discuss... Read more →

The Philosophical Foundations of Dualities in Physics

A conference on The Philosophical Foundations of Dualities in Physics (co-organised by Elena Castellani and Dean Rickles) will take place at DILEF (Dipartimento di Lettere e Filosofia), via Bolognese 52, Florence, on the 15 and 16 of September, 2014. The workshop is part of a Studies in the History and Philosophy of Modern Physics special issue project on the foundations of...

A simplified basis for Bell–Kochen–Specker theorems

James D. Malley and Arthur Fine We show that a reduced form of the structural requirements for deterministic hidden variables used in Bell–Kochen–Specker theorems is already sufficient for the no-go results. Those requirements are captured by the following principle: an observable takes a spectral value x if and only if the spectral projector associated with x takes the value 1.... Read more →

(Nearly) 90 Years of Heisenberg's Error-Disturbance Relation: Challenges and Vindications

Paul Busch (University of York) Submitted to "90 Years of Quantum Mechanics" In 1927 quantum pioneer Werner Heisenberg formulated his famous uncertainty principle, one aspect of which concerned a trade-off between the accuracy in the measurement of one observable and the resultant necessary disturbance of another observable incompatible with the first. Here we investigate why it has taken nearly 90... Read more →

John Bell's Varying Interpretations of Quantum Mechanics

H. Dieter Zeh Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem”. For the first time I met John Bell at the Varenna conference of 1970 (d’Espagnat, 1971). I had been invited on suggestion by Eugene P. Wigner, who had already helped me to publish my first paper on the concept of what was later called decoherence... Read more →

John Bell – The Irish Connection

Andrew Whitaker (Queen’s University Belfast) Submitted to "Quantum Nonlocality and Reality – 50 Years of Bell’s theorem". John Bell lived in Ireland for only 21 years, but throughout his life he remembered his Irish upbringing with fond memories, pride and gratitude. Ireland has a very respectable tradition in physics, and particularly mathematical physics (McCartney and Whitaker 2003). As early as... Read more →
