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

Published by on

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 →

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

Published by on

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… Read more →

On the Reality of the Wavefunction

Published by on

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 →

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

Published by on

We try to give a physical meaning to the wave function or quantum state of a system, apart from being a very efficient 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

Published by on | 1 Response

Jean Bricmont (IRMP, Universite 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

Published by on

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 →

Response to Wiseman, Rieffel, and Cavalcanti on Bell’s 1964 Paper

Published by on

Edward J. Gillis Wiseman has claimed that Bell was wrong in stating that determinism was inferred rather than assumed in the summary of the EPR argument in his 1964 paper. The reply of Wiseman and his co-authors to my comment misstates my reasons for disputing this point, and fails to address the central criticism that their claim is based on a seriously flawed… Read more →

Quantum Equivalence Principle In A Universal Hilbert Space

Published by on

Michael York We propose a unifying quantum framework in which Einstein’s equivalence principle is generalized to a universal Hilbert space in which all interaction is treated as a generalization of a frame transformation and represented by a change of basis. In our scheme intrinsic information is carried by a physical system independently of any frame of reference (or basis). A… Read more →

Emergence of Spacetime Through Interaction

Published by on

Furkan Semih Dündar and Baris Tamer Tonguc We study kinematics of atoms and molecules in quantum shape dynamics. We analyzed a model universe where there is only electrical force between protons and electrons. A similar model where there is only gravitational attraction between masses was investigated by Barbour, Koslowski and Mercati before. Our results is an expansion of the ideas there. We found… Read more →

Resolving the Problem of Definite Outcomes of Measurements

Published by on

Art Hobson (University of Arkansas) The entangled “Schrodinger’s cat state” of a quantum and its measurement apparatus is not a paradoxical superposition of states but is instead a non-paradoxical superposition of nonlocal coherent correlations between states: An un-decayed nucleus is correlated with a live cat, and a decayed nucleus is correlated with a dead cat. This elucidation of entanglement is demonstrated by quantum-theoretical analysis and… Read more →
