Yet, the proof of the `no-cloning theorem' is easy, and its consequences and potential for applications are immense. Similarly, why did it take us 60 years to discover the conceptually intriguing and easily derivable physical phenomenon of `quantum teleportation'? We claim that the quantum mechanical formalism doesn't support our intuition, nor does it elucidate the key concepts that govern the behaviour of the entities that are subject to the laws of quantum physics. The arrays of complex numbers are kin to the arrays of 0s and 1s of the early days of computer programming practice. Using a technical term from computer science, the quantum mechanical formalism is `low-level'. In this review we present steps towards a diagrammatic `high-level' alternative for the Hilbert space formalism, one which appeals to our intuition. The diagrammatic language as it currently stands allows for intuitive reasoning about interacting quantum systems, and trivialises many otherwise involved and tedious computations. It clearly exposes limitations such as the no-cloning theorem, and phenomena such as quantum teleportation. As a logic, it supports `automation': it enables a (classical) computer to reason about interacting quantum systems, prove theorems, and design protocols. -
Dynamical Relaxation to Quantum Equilibrium
Dynamical relaxation to quantum equilibrium Or, an account of Mike's attempt to write an entirely new computer code that doesn't do quantum Monte Carlo for the first time in years. ESDG, 10th February 2010 Mike Towler TCM Group, Cavendish Laboratory, University of Cambridge www.tcm.phy.cam.ac.uk/∼mdt26 and www.vallico.net/tti/tti.html [email protected] { Typeset by FoilTEX { 1 What I talked about a month ago (`Exchange, antisymmetry and Pauli repulsion', ESDG Jan 13th 2010) I showed that (1) the assumption that fermions are point particles with a continuous objective existence, and (2) the equations of non-relativistic QM, allow us to deduce: • ..that a mathematically well-defined ‘fifth force', non-local in character, appears to act on the particles and causes their trajectories to differ from the classical ones. • ..that this force appears to have its origin in an objectively-existing `wave field’ mathematically represented by the usual QM wave function. • ..that indistinguishability arguments are invalid under these assumptions; rather antisymmetrization implies the introduction of forces between particles. • ..the nature of spin. • ..that the action of the force prevents two fermions from coming into close proximity when `their spins are the same', and that in general, this mechanism prevents fermions from occupying the same quantum state. This is a readily understandable causal explanation for the Exclusion principle and for its otherwise inexplicable consequences such as `degeneracy pressure' in a white dwarf star. Furthermore, if assume antisymmetry of wave field not fundamental but develops naturally over the course of time, then can see character of reason for fermionic wave functions having symmetry behaviour they do. -

INFINITE POTENTIAL SHOW TITLE: GENERIC SHOW EPISODE #101 DATE: 3/17/20 TRANSCRIBED BY DAILY TRANSCRIPTION_TRE 00:00:28 DAVID BOHM People talked about the world, and I said, "Where does it end?" and, uh, uh... MALE And what answer did they give? DAVID BOHM Well, they-I never, uh, I don't remember. It wasn't terribly convincing I suppose. [LAUGH] DR. DAVID C. It was, uh, a night, and we were SCHRUM walking under the stars, black sky, and he looked up to the stars, and he said, "Ordinarily, when we look to the sky and look to the stars, we think of stars as objects far out and vast spaces between them." He said, "There's another way we can look at it. We can look at the vacuum at the emptiness instead as a planum, as infinitely full rather than infinitely empty. And that the material objects themselves are like little bubbles, little vacancies in this vast sea." 00:01:25 DR. DAVID C. So David Bohm, in a sense, was SCHRUM using that view to have me look at the stars and to have a sense of the night sky all of a sudden in a different way, as one whole living organism and these little bits that we call matter as sort to just little holes in it. DR. DAVID C. He often mentioned just one other SCHRUM aspect of this, that this planum, in a cubic centimeter of the planum, there's more, uh, energy matter than in the entire visible Page 2 of 62 universe. -

Truth begins in sense experience, but does not end there. Positivism fails to prove that there are not abstract ideas, laws, and principles, beyond particular observable facts and relationships and necessary principles, or that we cannot know them. Nor does it prove that material and corporeal things constitute the whole order of existing beings, and that our knowledge is limited to them. Positivism ignores all humanly significant and interesting problems, citing its refusal to engage in reflection; it gives to a particular methodology an absolutist status and can do this only because it has partly forgotten, partly repressed its knowledge of the roots of this methodology in human concerns. -

CORE Metadata, citation and similar papers at core.ac.uk Provided by SAS-SPACE Published: Louis Caruana, ‘John von Neumann's “Impossibility Proof” in a Historical Perspective’, Physis 32 (1995), pp. 109-124. JOHN VON NEUMANN'S ‘IMPOSSIBILITY PROOF’ IN A HISTORICAL PERSPECTIVE ABSTRACT John von Neumann's proof that quantum mechanics is logically incompatible with hidden varibales has been the object of extensive study both by physicists and by historians. The latter have concentrated mainly on the way the proof was interpreted, accepted and rejected between 1932, when it was published, and 1966, when J.S. Bell published the first explicit identification of the mistake it involved. What is proposed in this paper is an investigation into the origins of the proof rather than the aftermath. In the first section, a brief overview of the his personal life and his proof is given to set the scene. There follows a discussion on the merits of using here the historical method employed elsewhere by Andrew Warwick. It will be argued that a study of the origins of von Neumann's proof shows how there is an interaction between the following factors: the broad issues within a specific culture, the learning process of the theoretical physicist concerned, and the conceptual techniques available. In our case, the ‘conceptual technology’ employed by von Neumann is identified as the method of axiomatisation. 1. INTRODUCTION A full biography of John von Neumann is not yet available. Moreover, it seems that there is a lack of extended historical work on the origin of his contributions to quantum mechanics. -
David Bohm's Theory of the Implicate Order: Implications for Holistic Thought Processes*
ISSUES IN INTEGRATVE STUDIES No. 13, pp. 1-23 (1995) David Bohm's Theory of the Implicate Order: Implications for Holistic Thought Processes* by Irene J. Dabrowski, Ph.D. Division of Social Services, St. John's University, New York Abstract: David Bohm's theory of quantum physics, which focuses on the schism between matter and consciousness, is discussed in terms of positivist knowledge and the interdisciplinary holistic paradigm. This paper examines how scientific and educational holism, predicated on the relationship between knowledge and reality, fosters innovative approaches such as evolutionary learning, a pedagogical application of general systems theory. In pursuit of right- brain thought and a unified knowledge base, diverse modes of inquiry are presented in the context of Bohm's thesis of an implicate order. Given that holistic thought processes generate a reality-based knowledge, problem-solving styles are examined, which reveal the holistic orientation of proactive problem-solving. Interdisciplinary dialogue is identified as an essential way for moving toward holistic expressions and networks of thought. NEW VERSIONS of the sciences as well as other academic disciplines are being formulated in terms of a naturalistic mode of inquiry (Lincoln, 1989; Palm, 1979). The emergent post-positivist paradigm is directed toward a holistic conception of reality, replacing the Cartesian, mechanistic mode of conceptualization (Capra, 1982; Guba, 1981; Lincoln, 1989; Turner, 1990), In fact, characteristics of the "whole paradigm" are being identified in a variety of disciplines (Lincoln, 1989, p. 69). New dimensions include a refocusing from simple to complex realities, the movement from the mechanical to the holographic, and the emphasis from linear to mutual causality (Lincoln & Guba, 1985; Macy, 1991; Schwartz & Ogilvy, 1979). -

I explore the concept of speculation in particle physics and science fiction to examine emergent critical approaches for working in the two areas of literature and physics (the latter through critical science studies), but with the expectation of contributing new insights to media theory, critical code studies, and also the science studies of science fiction. -

Bohm's approach to quantum mechanics: Alternative theory or practical picture? A. S. Sanz∗ Department of Optics, Faculty of Physical Sciences, Universidad Complutense de Madrid, Pza. Ciencias 1, Ciudad Universitaria E-28040 Madrid, Spain Since its inception Bohmian mechanics has been generally regarded as a hidden-variable theory aimed at providing an objective description of quantum phenomena. To date, this rather narrow conception of Bohm's proposal has caused it more rejection than acceptance. Now, after 65 years of Bohmian mechanics, should still be such an interpretational aspect the prevailing appraisal? Why not favoring a more pragmatic view, as a legitimate picture of quantum mechanics, on equal footing in all respects with any other more conventional quantum picture? These questions are used here to introduce a discussion on an alternative way to deal with Bohmian mechanics at present, enhancing its aspect as an efficient and useful picture or formulation to tackle, explore, describe and explain quantum phenomena where phase and correlation (entanglement) are key elements. This discussion is presented through two complementary blocks. The first block is aimed at briefly revisiting the historical context that gave rise to the appearance of Bohmian mechanics, and how this approach or analogous ones have been used in different physical contexts. This discussion is used to emphasize a more pragmatic view to the detriment of the more conventional hidden-variable (ontological) approach that has been a leitmotif within the quantum foundations. The second block focuses on some particular formal aspects of Bohmian mechanics supporting the view presented here, with special emphasis on the physical meaning of the local phase field and the associated velocity field encoded within the wave function. -
