Point-like Particles in Fuzzy Space-time

Charles Francis

Published Jan 30, 1999• 0 citations
arXivHTMLPDF

Abstract

This paper is withdrawn as I am no longer using the term "fuzzy space- time" to describe the uncertainty in co-ordinate systems implicit in quantum logic. Nor am I using the interpretation that quantum logic can be regarded as a special case of fuzzy logic. This is because there are sufficient differences between quantum logic and fuzzy logic that the explanation is confusing. I give an interpretation of quantum logic in "A Theory of Quantum Space-time"

Square Root of \Not": A Major Difierence Between Fuzzy and

Quantum Logics, Владик Крейнович, Ladislav Kohout +1 more

Many authors have mentioned the similarity between quantum logic and fuzzy logic. In this paper, we show that, in spite of this similarity, these logics are identical. Speciflcally, we emphasize that while quantum logic has a special \square root of not operation which is very useful in quantum computing, fuzzy logic lacks such an operation.

Can Fuzzy Sets Be Useful in the (Re) Interpretation of Uncertainty in Quantum Mechanics?

Rudolf Seising

New scientific theories have been and will always be required for the progress of science. Two examples of new theories that were advanced in the 20th century are quantum mechanics and fuzzy set theory. Both deal with the concept of uncertainty and both use mathematical tools that are essentially different from those used in classical probability theory. In both, the introduction of new concepts (theoretical terms) was necessary because phenomena and processes observed in the real world could not be explained with existing mathematical concepts. This paper examines the possibilities of (re)interpreting uncertainty in quantum mechanics with the aid of fuzzy sets and systems

Fuzzy Systems to Quantum Mechanics

Hongxing Li

"This unique compendium represents important action of fuzzy systems to quantum mechanics. From fuzzy sets to fuzzy systems, it also gives clear descriptions on the development on fuzzy logic, where the most important result is the probability presentation of fuzzy systems. The important conclusions on fuzzy systems are used in the study of quantum mechanics, which is a very new idea. Eight important conclusions are obtained. The author has proved that mass-point motions in classical mechanics must have waves, which means that any mass-point motion in classical mechanics has wave mass-point dualism as well as any microscopic particle motion must have wave-particle dualism. Based on this conclusion, it has been proven that classical mechanics and quantum mechanics are unified."--Publisher's website

An Interpretation of Quantum Logic

Charles Francis

It is argued that the orthodox interpretation of quantum mechanics is in conflict with the objective existence of space-time, and suggested that kets are labels which name real states of matter but do not directly describe them. Position is a relationship between particles which necessarily contains uncertainty. The principle of superposition is seen as a definitional truism in the naming of states. The description of space in quantum logic resolves the measurement problem of quantum mechanics and related paradoxes such as Schrodinger's cat by attributing the collapse of the wave function to information.

The Fuzzy Bit

Milagrosa Aldana, M. A. Lledó

In this paper, the formulation of Quantum Mechanics in terms of fuzzy logic and fuzzy sets is explored. A result by Pykacz, which establishes a correspondence between (quantum) logics (lattices with certain properties) and certain families of fuzzy sets, is applied to the Birkhoff–von Neumann logic, the lattice of projectors of a Hilbert space. Three cases are considered: the qubit, two qubits entangled, and a qutrit ‘nested’ inside the two entangled qubits. The membership functions of the fuzzy sets are explicitly computed and all the connectives of the fuzzy sets are interpreted as operations with these particular membership functions. In this way, a complete picture of the standard quantum logic in terms of fuzzy sets is obtained for the systems considered.
