Non-locality in Quantum Mechanics and Bell’s Inequality
Bell’s inequality makes it possible to test if there are long-distance correlations due to entanglement, even at space-like distances. This topic has...

Quantum Theories with Local Information Flow
Bell non-locality is a term that applies to specific modifications and interpretations of quantum mechanics. Yet, Bell’s original 1964 theorem is...

Quantum postulate vs. quantum nonlocality: on the role of the Planck constant in Bell’s argument
We present a quantum mechanical (QM) analysis of Bell’s approach to quantum foundations based on his hidden-variable model. We claim and try to...

A Quintet of Quandaries: Five No-Go Theorems for Relational Quantum Mechanics
Relational quantum mechanics (RQM) proposes an ontology of relations between physical systems, where any system can serve as an ‘observer’ and any...

On the Strangeness of Quantum Mechanics
The extravagances of quantum mechanics (QM) never fail to enrich daily the debate around natural philosophy. Entanglement, non-locality, collapse,...

Non-local characteristics of deleting machine
In this paper, we introduce a new deletion machine and its reverse. We compare the fidelity of retention and fidelity of deletion for both deleting...

The Reasoning of Quantum Mechanics Operator Theory and the Harmonic Oscillator
This book presents and details the process of quantization of a classical mechanical system in a relevant physical system, the harmonic oscillator....
-
Nonlocality
In this chapter, we describe and discuss the Einstein-Podolsky-Rosen (EPR) argument (and variants of it) and JohnA Bell’s proof of nonlocality. We...

What Does ‘(Non)-absoluteness of Observed Events’ Mean?
Recently there have emerged an assortment of theorems relating to the ‘absoluteness of emerged events,’ and these results have sometimes been used to...

Classically verifiable quantum advantage from a computational Bell test
Existing experimental demonstrations of quantum computational advantage have had the limitation that verifying the correctness of the quantum device...

von Neumann’s Theorem Revisited
According to a popular narrative, in 1932 von Neumann introduced a theorem that intended to be a proof of the impossibility of hidden variables in...

Bohr on EPR, the Quantum Postulate, Determinism, and Contextuality
The famous EPR article of 1935 challenged the completeness of quantum mechanics and spurred decades of theoretical and experimental research into the...

“Without in Any Way Disturbing the System”: Reality, Probability, and Nonlocality, from Bohr to Bell and Beyond
While continuing the exploration of Bohr’s thinking, this chapter aims to contribute to the ongoing task of clarifying the relationships among...

An Alternative Foundation of Quantum Theory
A new approach to quantum theory is proposed in this paper. The basis is taken to be theoretical variables, variables that may be accessible or...

Bell Non-Locality in Many-Body Quantum Systems with Exponential Decay of Correlations
Using Bell inequalities as a tool to explore non-classical physical behaviours, in this paper we analyse what one can expect to find in many-body...

Indeterminism and Undecidability
The aim of this paper is to argue that the (alleged) indeterminism of quantum mechanics, claimed by adherents of the Copenhagen interpretation since...

Autobiographical Notes of a Physicist
I describe aspects of my life in physics: the name I publish under, great physicists I have known, how I got into quantum foundations, what role I’ve...

Introduction
In this introduction, we joins the contributors to this collection in celebrating Andrei Khrennikov’s to both quantum foundationsQuantum...

The Changing Bell View of Beables: A Forgotten Story
John S. Bell is known, among other things, for the introduction of the notion of beable. The development of this notion inspired the so-called...
