## Particle or wave: there is no evidence of single photon delayed choice

Michael Devereux (Los Alamos National Laboratory) Wheeler supposed that the way in which a single photon is measured in the present could determine how it had behaved in the past. He named such retrocausation delayed choice. Over the last forty years many experimentalists have claimed to have observed single-photon delayed choice. Recently, however, researchers have proven that the quantum wavefunction of a single photon... Read more →

## On the Status of the Measurement Problem: Recalling the Relativistic Transactional Interpretation

ABSTRACT. In view of a resurgence of concern about the measurement problem, it is pointed out that the Relativistic Transactional Interpretation (RTI) remedies issues previously considered as drawbacks or refutations of the original TI. Specifically, once one takes into account relativistic processes that are not representable at the non-relativistic level (such as particle creation and annihilation, and virtual propagation), absorption...

The Consciousness of Embodied Cognition, Affordances, and the Brain brain [x] consciousness [x] experience [x] phenomenal [x] add tag Latest Results for Topoi on 2017-9-21 5:00am Abstract Tony Chemero advances the radical thesis that cognition and consciousness are actually the same thing. I question this conclusion. Even if we are the brain–body environmental synergies that Chemero and others claim, we will not be able to conclude that consciousness... Read more →

## A Reformulation of von Neumann’s Postulates on Quantum Measurement by Using Two Theorems in Clifford Algebra

Elio Conte According to a procedure previously introduced from Y. Ilamed and N. Salingaros, we start giving proof of two existing Clifford algebras, the Si that has isomorphism with that one of Pauli matrices and the Ni,±1 where Ni stands for the dihedral Clifford algebra. The salient feature is that we show that the Ni,±1 may be obtained from the Si algebra when we...

## On the Reality of the Wavefunction

Dear All, Recently, I have written a paper arguing against the claim of the PBR theorem. That is, I have shown that statistics of PBR's scenario can be reproduced by $\psi$-epistemic ontological models. However, the only thing that is required is to consider the role of the measurement ontic states. In what follows, I have provided the abstract of the... Read more →

## Quantum mechanics from an epistemic state space

Per Östborn (Lund University, Sweden) We derive the Hilbert space formalism of quantum mechanics from epistemic principles. A key assumption is that a physical theory that relies on entities or distinctions that are unknowable in principle gives rise to wrong predictions. An epistemic formalism is developed, where concepts like individual and collective knowledge are used, and knowledge may be actual... Read more →

## The De Broglie-Bohm Theory As A Rational Completion Of Quantum Mechanics

We try to give a physical meaning to the wave function or quantum state of a system, apart from being a very efficient tool for predicting results of measurements on that system. In other words, we ask: what does it mean for a system outside the laboratories to have a wave function? We first explain why two possible, and probably common, answers to... Read more →

## History of Quantum Mechanics or the Comedy of Errors

Jean Bricmont (IRMP, Universite catholique de Louvain) The goal of this paper is to explain how the views of Albert Einstein, John Bell and others, about nonlocality and the conceptual issues raised by quantum mechanics, have been rather systematically misunderstood by the majority of physicists.

## Quantum nonlocality observable on a non-statistical level: idea, experimental evidence, fundamental consequences

Sergey A. Emelyanov (A. F. Ioffe Institute) Today quantum nonlocality is discussed only in the context of EPR situation where we face a macroscopic system which is fundamentally indivisible insofar as it consists of entangled distant particles. But quantum formalism implies a one more type of indivisibility. It is the indivisibility of a quantum state per se regardless of its... Read more →

## Entangled history?

Did anyone read the papers by Wilczek on entangled history? Any comment?
