Locality and measurements within the SR model for an objective interpretation of quantum mechanics
One of the authors has recently propounded an SR (semantic realism) model
which shows, circumventing known no-go theorems, that an objective
(noncontextual, hence local) interpretation of quantum mechanics (QM) is
possible. We consider here compound physical systems and show why the proofs of
nonlocality of QM do not hold within the SR model. We also discuss quantum
measurement theory within this model, note that the objectification problem
disappears since the measurement of any property simply reveals its unknown
value, and show that the projection postulate can be considered as an
approximate law, valid FAPP (for all practical purposes). Finally, we provide
an intuitive justification for some unusual features of the SR model.Comment: 29 pages, minor correction
Superpositional Quantum Network Topologies
We introduce superposition-based quantum networks composed of (i) the
classical perceptron model of multilayered, feedforward neural networks and
(ii) the algebraic model of evolving reticular quantum structures as described
in quantum gravity. The main feature of this model is moving from particular
neural topologies to a quantum metastructure which embodies many differing
topological patterns. Using quantum parallelism, training is possible on
superpositions of different network topologies. As a result, not only classical
transition functions, but also topology becomes a subject of training. The main
feature of our model is that particular neural networks, with different
topologies, are quantum states. We consider high-dimensional dissipative
quantum structures as candidates for implementation of the model.Comment: 10 pages, LaTeX2
Static Quantum Games Revisited
The so called \emph{quantum game theory} has recently been proclaimed as one
of the new branches in the development of both quantum information theory and
game theory. However, the notion of a quantum game itself has never been
strictly defined, which has led to a lot of conceptual confusion among
different authors. In this paper we introduce a new conceptual framework of a
\emph{scenario} and an \emph{implementation} of a game. It is shown that the
procedures of "quantization" of games proposed in the literature lead in fact
to several different games which can be defined within the same scenario, but
apart from this they may have nothing in common with the original game. Within
the framework we put forward, a lot of conceptual misunderstandings that have
arisen around "quantum games" can be stated clearly and resolved uniquely. In
particular, the proclaimed essential role of entanglement in several static
"quantum games", and their connection with Bell inequalities, is disproved
How to play two-players restricted quantum games with 10 cards
We show that it is perfectly possible to play 'restricted' two-players,
two-strategies quantum games proposed originally by Marinatto and Weber having
as the only equipment a pack of 10 cards. The 'quantum board' of such a model
of these quantum games is an extreme simplification of 'macroscopic quantum
machines' proposed by one of the authors in numerous papers that allow to
simulate by macroscopic means various experiments performed on two entangled
quantum objectsComment: 4 pages, 3 figure
Quantum structures and the nature of reality: the indigo book of "Einstein meets Magritte"
Quantum Structures and the Nature of Reality is a collection of papers written for an interdisciplinary audience about the quantum structure research within the International Quantum Structures Association. The advent of quantum mechanics has changed our scientific worldview in a fundamental way. Many popular and semi-popular books have been published about the paradoxical aspects of quantum mechanics. Usually, however, these reflections find their origin in the standard views on quantum mechanics, most of all the wave-particle duality picture. Contrary to relativity theory, where the meaning of its revolutionary ideas was linked from the start with deep structural changes in the geometrical nature of our world, the deep structural changes about the nature of our reality that are indicated by quantum mechanics cannot be traced within the standard formulation. The study of the structure of quantum theory, its logical content, its axiomatic foundation, has been motivated primarily by the search for their structural changes. Due to the high mathematical sophistication of this quantum structure research, no books have been published which try to explain the recent results for an interdisciplinary audience. This book tries to fill this gap by collecting contributions from some of the main researchers in the field. They reveal the steps that have been taken towards a deeper structural understanding of quantum theory
