Collapse-in and Collapse-out in Partial Measurement in Quantum Mechanics and its WISE Interpretation

Published by on

Gui-Lu Long (Tsinghua University) SCIENCE CHINA Physics, Mechanics & Astronomy, (2021)  https://doi.org/10.1007/s11433-021-1716-y In this short communication, we will concentrate onthe partial measurement issue and give an explanationconcerning the WISE interpretation. The essential ideaof WISE is given in Ref. [4], together with the linearcombination of unitaries (LCU) formalism of quantumcomputing. LCU has now become one of the major techniquesin quantum algorithm design…. Read more →

The Quantum Measurement Problem

Published by on

The quantum measurement problem is the most fundamental question of all: How the ghostly quantum mechanical coexistence of many mutually incompatible possibilities result in the concrete reality of the normal world, even though we and our measuring instruments are all made of atoms obeying quantum mechanics. In this brief article we lay down the criteria for such a mechanism.

Superselection rule in the problem of scattering a particle on a one-dimensional delta-potential

Published by on

Recently, discussions of fundamental problems of (non-relativistic) quantum mechanics usually concern Bell’s inequalities. As for the discussions around the Schrödinger’s cat paradox, they faded into the background. At the same time, the discussion of Bell’s inequalities suggests that the Schrödinger’s cat paradox has already been resolved. Therefore, it is worth returning to the Schrödinger’s cat paradox to make sure that,… Read more →

The kh{\^o}ra and the two-triangle universe of Plato’s Timaeus. (arXiv:2008.11947v1 [math.HO]) 上午8:56 | physics.hist-ph updates on arXiv.org Authors: Luc Brisson, Salomon Ofman (IMJ-PRG (UMR\_7586)) The main purpose of this article is to try to understand the connection between the physical universe and the mathematical principles that underlies the cosmological account of the Timaeus. Aristotle’s common criticism of Plato’s cosmology is that he confuses… Read more →

Revised submission: Decoherence and the Transactional Interpretation

Published by on

In response to reviewer comments, I am posting a sightly revised version of my previously submitted paper. Editor: please note that my emails to you are not getting through at the moment, so please consider this my resubmission. Many thanks. ABSTRACT: This paper presents an analysis of decoherence resulting from the physically real non-unitarity, or ‘objective reduction,’ that occurs in… Read more →

The classical and the quantum paper

Published by on

Hi, I would greatly appreciate any comments and critique of the paper https://arxiv.org/abs/1912.05914 with the abstract copied below. Thank you. -Alexey Newtonian and Schroedinger dynamics can be formulated in a physically meaningful way within the same Hilbert space framework. This fact was recently used to discover an unexpected relation between classical and quantum motions that goes beyond the results provided… Read more →

Decoherence in the Transactional Interpretation

Published by on

Abstract. This paper presents an analysis of decoherence resulting from the physically real non-unitarity, or ‘objective reduction,’ that occurs in the Transactional Interpretation (TI).  Two distinct aspects of the decoherence process are identified and disambiguated; specifically, (i) the resolution of the basic measurement interaction with respect to the observable under study, and (ii) the effect on the measured system of… Read more →
