    Quantum Mechanics is About Quantum Information.Jeffrey Bub - 2005 - Foundations of Physics 35 (4):541-560.
    I argue that quantum mechanics is fundamentally a theory about the representation and manipulation of information, not a theory about the mechanics of nonclassical waves or particles. The notion of quantum information is to be understood as a new physical primitive—just as, following Einstein’s special theory of relativity, a field is no longer regarded as the physical manifestation of vibrations in a mechanical medium, but recognized as a new physical primitive in its own right.

    A Matter of Principle: The Principles of Quantum Theory, Dirac’s Equation, and Quantum Information.Arkady Plotnitsky - 2015 - Foundations of Physics 45 (10):1222-1268.
    This article is concerned with the role of fundamental principles in theoretical physics, especially quantum theory. The fundamental principles of relativity will be addressed as well, in view of their role in quantum electrodynamics and quantum field theory, specifically Dirac’s work, which, in particular Dirac’s derivation of his relativistic equation of the electron from the principles of relativity and quantum theory, is the main focus of this article. I shall also consider Heisenberg’s earlier work leading him (...)

    Boolean Information Sieves: A Local-to-Global Approach to Quantum Information.Elias Zafiris - 2010 - International Journal of General Systems 39 (8):873-895.
    We propose a sheaf-theoretic framework for the representation of a quantum observable structure in terms of Boolean information sieves. The algebraic representation of a quantum observable structure in the relational local terms of sheaf theory effectuates a semantic transition from the axiomatic set-theoretic context of orthocomplemented partially ordered sets, la Birkhoff and Von Neumann, to the categorical topos-theoretic context of Boolean information sieves, la Grothendieck. The representation schema is based on the existence of a categorical adjunction, (...)

  4. Bohmian Mechanics and Quantum Information.Sheldon Goldstein - 2010 - Foundations of Physics 40 (4):335-355.
    Many recent results suggest that quantum theory is about information, and that quantum theory is best understood as arising from principles concerning information and information processing. At the same time, by far the simplest version of quantum mechanics, Bohmian mechanics, is concerned, not with information but with the behavior of an objective microscopic reality given by particles and their positions. What I would like to do here is to examine whether, and to what (...)

    Quantum Information and Inferential Reasoning.Gennaro Auletta - 2005 - Foundations of Physics 35 (1):155-156.
    Information may be extracted from a quantum–mechanical system only by means of inference. For this reason, the observer, although not required as such for obtaining an eigenstate of the measured observable on a given system, is necessary for obtaining information.

    This report reviews what quantum physics and information theory have to tell us about the age-old question, How come existence? No escape is evident from four conclusions: (1) The world cannot be a giant machine, ruled by any preestablished continuum physical law. (2) There is no such thing at the microscopic level as space or time or spacetime continuum. (3) The familiar probability function or functional, and wave equation or functional wave equation, of standard quantum theory provide (...)

    Quantum Information Biology: From Information Interpretation of Quantum Mechanics to Applications in Molecular Biology and Cognitive Psychology.Masanari Asano, Irina Basieva, Andrei Khrennikov, Masanori Ohya, Yoshiharu Tanaka & Ichiro Yamato - 2015 - Foundations of Physics 45 (10):1362-1378.
    We discuss foundational issues of quantum information biology —one of the most successful applications of the quantum formalism outside of physics. QIB provides a multi-scale model of information processing in bio-systems: from proteins and cells to cognitive and social systems. This theory has to be sharply distinguished from “traditional quantum biophysics”. The latter is about quantum bio-physical processes, e.g., in cells or brains. QIB models the dynamics of information states of bio-systems. We argue (...)

    Quantum Information Theory and the Foundations of Quantum Mechanics.Christopher Gordon Timpson - 2013 - Oxford University Press.
    Christopher G. Timpson provides the first full-length philosophical treatment of quantum information theory and the questions it raises for our understanding of the quantum world. He argues for an ontologically deflationary account of the nature of quantum information, which is grounded in a revisionary analysis of the concepts of information.

  9. Explaining the Unobserved—Why Quantum Mechanics Ain’T Only About Information.Amit Hagar & Meir Hemmo - 2006 - Foundations of Physics 36 (9):1295-1234.
    A remarkable theorem by Clifton, Bub and Halvorson (2003) (CBH) characterizes quantum theory in terms of information--theoretic principles. According to Bub (2004, 2005) the philosophical significance of the theorem is that quantum theory should be regarded as a ``principle'' theory about (quantum) information rather than a ``constructive'' theory about the dynamics of quantum systems. Here we criticize Bub's principle approach arguing that if the mathematical formalism of quantum mechanics remains intact then there is (...)

    Quantum Theory is Not Only About Information.Laura Felline - 2018 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics.
    In his recent book Bananaworld. Quantum mechanics for primates, Jeff Bub revives and provides a mature version of his influential information-theoretic interpretation of Quantum Theory (QT). In this paper, I test Bub’s conjecture that QT should be interpreted as a theory about information, by examining whether his information-theoretic interpretation has the resources to explain (or explain away) quantum conundrums. The discussion of Bub’s theses will also serve to investigate, more in general, whether other approaches (...)

    On the Common Structure of the Primitive Ontology Approach and the Information-Theoretic Interpretation of Quantum Theory.Lucas Dunlap - 2015 - Topoi 34 (2):359-367.
    We use the primitive ontology framework of Allori et al. to analyze the quantum information-theoretic interpretation of Bub and Pitowsky. There are interesting parallels between the two approaches, which differentiate them both from the more standard realist interpretations of quantum theory. Where they differ, however, is in terms of their commitments to an underlying ontology on which the manifest image of the world supervenes. Employing the primitive ontology framework in this way makes perspicuous the differences between the (...)

    Quantum Information - What Price Realism?Amit Hagar - 2005 - Intl. J. Of Quantum Information 3 (1):165-170.
    Recent suggestions to supply quantum mechanics (QM) with realistic foundations by reformulating it in light of quantum information theory (QIT) are examined and are found wanting by pointing to a basic conceptual problem that QIT itself ignores, namely, the measurement problem. Since one cannot ignore the measurement problem and at the same time pretend to be a realist, as they stand, the suggestions to reformulate QM in light of QIT are nothing but instrumentalism in disguise.

  15. Characterizing Quantum Theory in Terms of Information-Theoretic Constraints.Rob Clifton, Jeffrey Bub & Hans Halvorson - 2002 - Foundations of Physics 33 (11):1561-1591.
    We show that three fundamental information-theoretic constraints -- the impossibility of superluminal information transfer between two physical systems by performing measurements on one of them, the impossibility of broadcasting the information contained in an unknown physical state, and the impossibility of unconditionally secure bit commitment -- suffice to entail that the observables and state space of a physical theory are quantum-mechanical. We demonstrate the converse derivation in part, and consider the implications of alternative answers to a (...)

    It's a Matter of Principle: Scientific Explanation in Information‐Theoretic Reconstructions of Quantum Theory.Laura Felline - 2016 - Dialectica 70 (4):549-575.
    The aim of this paper is to explore the ways in which Axiomatic Reconstructions of Quantum Theory in terms of Information-Theoretic principles can contribute to explaining and understanding quantum phenomena, as well as to study their explanatory limitations. This is achieved in part by offering an account of the kind of explanation that axiomatic reconstructions of Quantum Theory provide, and re-evaluating the epistemic status of the program in light of this explanation. As illustrative case studies, I (...)

    Quantum Theory is an Information Theory.Giacomo M. D’Ariano & Paolo Perinotti - 2016 - Foundations of Physics 46 (3):269-281.
    In this paper we review the general framework of operational probabilistic theories, along with the six axioms from which quantum theory can be derived. We argue that the OPT framework along with a relaxed version of five of the axioms, define a general information theory. We close the paper with considerations about the role of the observer in an OPT, and the interpretation of the von Neumann postulate and the Schrödinger-cat paradox.

    Isolation and Information Flow in Quantum Dynamics.Benjamin Schumacher & Michael D. Westmoreland - 2012 - Foundations of Physics 42 (7):926-931.
    From the structure of quantum dynamics for closed and open systems, we describe several general results about information flow between interacting systems, which can be expressed in diagrammatic form. Conditions on information flow (e.g., that no information is transferred from system A to system B) imply that the overall dynamical evolution has a particular structure. We also remark that one simple type of two-qubit interaction, the unitary CNOT gate, cannot be represented by local operations and a (...)

    The Information Interpretation and the Conceptual Problems of Quantum Mechanics.Miguel Ferrero - 2003 - Foundations of Physics 33 (4):665-676.
    It has been traditionally considered that Quantum Mechanics has two conceptual kinds of problems, namely, those related with local-realism and the so-called measurement problem. That is, the uniqueness of the result when we make a measurement. With the development of what is called generically Quantum Information Theory, a new form of the Copenhagen interpretation of the formalism has taken shape.(1) In this paper, we will analyse if this information interpretation is able to clarify these old problems.

    Quantum Theory Beyond the Physical: Information in Context.Kirsty Kitto, Brentyn Ramm, Laurianne Sitbon & Peter Bruza - 2011 - Axiomathes 21 (2):331-345.
    Measures and theories of information abound, but there are few formalised methods for treating the contextuality that can manifest in different information systems. Quantum theory provides one possible formalism for treating information in context. This paper introduces a quantum inspired model of the human mental lexicon. This model is currently being experimentally investigated and we present a preliminary set of pilot data suggesting that concept combinations can indeed behave non-separably.

    Information Invariance and Quantum Probabilities.Časlav Brukner & Anton Zeilinger - 2009 - Foundations of Physics 39 (7):677-689.
    We consider probabilistic theories in which the most elementary system, a two-dimensional system, contains one bit of information. The bit is assumed to be contained in any complete set of mutually complementary measurements. The requirement of invariance of the information under a continuous change of the set of mutually complementary measurements uniquely singles out a measure of information, which is quadratic in probabilities. The assumption which gives the same scaling of the number of degrees of freedom with (...)

    Non-Local Correlations in Therapeutic Settings? A Qualitative Study on the Basis of Weak Quantum Theory and the Model of Pragmatic Information.Anja Matschuck - 2011 - Axiomathes 21 (2):249-261.
    Weak Quantum Theory (WQT) and the Model of Pragmatic Information (MPI) are two psychophysical concepts developed on the basis of quantum physics. The present study contributes to their empirical examination. The issue of the study is whether WQT and MPI can not only explain ‘psi’-phenomena theoretically but also prove to be consistent with the empirical phenomenology of extrasensory perception (ESP). From the main statements of both models, 33 deductions for psychic readings are derived. Psychic readings are defined (...)

    We present a novel spontaneous collapse model where size is no longer the property of a physical system which determines its rate of collapse. Instead, we argue that the rate of spontaneous localization should depend on a system’s quantum Integrated Information, a novel physical property which describes a system’s capacity to act like a quantum observer. We introduce quantum Integrated Information, present our QII collapse model and briefly explain how it may be experimentally tested against (...)

    Quantum Mechanics Emerges From Information Theory Applied to Causal Horizons.Jae-Weon Lee - 2011 - Foundations of Physics 41 (4):744-753.
    It is suggested that quantum mechanics is not fundamental but emerges from classical information theory applied to causal horizons. The path integral quantization and quantum randomness can be derived by considering information loss of fields or particles crossing Rindler horizons for accelerating observers. This implies that information is one of the fundamental roots of all physical phenomena. The connection between this theory and Verlinde’s entropic gravity theory is also investigated.

    Nonlocal Quantum Information Transfer Without Superluminal Signalling and Communication.Jan Walleczek & Gerhard Grössing - 2016 - Foundations of Physics 46 (9):1208-1228.
    It is a frequent assumption that—via superluminal information transfers—superluminal signals capable of enabling communication are necessarily exchanged in any quantum theory that posits hidden superluminal influences. However, does the presence of hidden superluminal influences automatically imply superluminal signalling and communication? The non-signalling theorem mediates the apparent conflict between quantum mechanics and the theory of special relativity. However, as a ‘no-go’ theorem there exist two opposing interpretations of the non-signalling constraint: foundational and operational. Concerning Bell’s theorem, we argue (...)

    Hiding Information in Theories Beyond Quantum Mechanics, and It's Application to the Black Hole Information Problem.Markus P. Müller, Jonathan Oppenheim & Oscar C. O. Dahlsten - 2014 - Foundations of Physics 44 (8):829-842.
    The black hole information problem provides important clues for trying to piece together a quantum theory of gravity. Discussions on this topic have generally assumed that in a consistent theory of gravity and quantum mechanics, quantum theory is unmodified. In this review, we discuss the black hole information problem in the context of generalisations of quantum theory. In this preliminary exploration, we examine black holes in the setting of generalised probabilistic theories, in which (...) theory and classical probability theory are special cases. We are able to calculate the time it takes information to escape a black hole, assuming that information is preserved. In quantum mechanics, information should escape pure state black holes after half the Hawking photons have been emitted, but we find that this get’s modified in generalisations of quantum mechanics. Likewise the black-hole mirror result of Hayden and Preskill, that information from entangled black holes can escape quickly, also get’s modified. We find that although information exits the black hole as predicted by quantum theory, it is fairly generic that it fails to appear outside the black hole at this point—something impossible in quantum theory due to the no-hiding theorem. The information is neither inside the black hole, nor outside it, but is delocalised. (shrink)

    Quantum Information as a General Paradigm.Gennaro Auletta - 2005 - Foundations of Physics 35 (5):787-815.
    Quantum–mechanical systems may be understood in terms of information. When they interact, they modify the information they carry or represent in two, and only two, ways: by selecting a part of the initial amount of (potential) information and by sharing information with other systems. As a consequence, quantum systems are informationally shielded. These features are shown to be general features of nature. In particular, it is shown that matter arises from quantum–mechanical processes through (...)

    What is Quantum Information?Olimpia Lombardi, Federico Holik & Leonardo Vanni - 2016 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 56:17-26.
    In the present paper we develop different arguments to show that there are no reasons to consider that there exists quantum information as qualitatively different than Shannon information. There is only one kind of information, which can be coded by means of orthogonal or non-orthogonal states. The analogy between Shannon’s theory and Schumacher’s theory is confined to coding theorems. The attempt to extend the analogy beyond this original scope leads to a concept of quantum (...) that becomes indistinguishable from that of quantum state. But information is essentially linked with communication, as it is clear in both Shannon’s and Schumacher’s proposals. If we detach information from this link, we are not talking about information but about quantum mechanics. We also stress the neutrality of information with respect to the physical theories that describe the systems used for its implementation. This view opens the way towards a non-reductive unification of physics: if different physical theories can be reconstructed on the same neutral informational basis, they could be meaningfully compared with no need of searching for reductive links among them.

    A Quantum-Information-Theoretic Complement to a General-Relativistic Implementation of a Beyond-Turing Computer.Christian Wüthrich - 2015 - Synthese 192 (7):1989-2008.
    There exists a growing literature on the so-called physical Church-Turing thesis in a relativistic spacetime setting. The physical Church-Turing thesis is the conjecture that no computing device that is physically realizable can exceed the computational barriers of a Turing machine. By suggesting a concrete implementation of a beyond-Turing computer in a spacetime setting, Istvan Nemeti and Gyula David have shown how an appreciation of the physical Church-Turing thesis necessitates the confluence of mathematical, computational, physical, and indeed cosmological ideas. In this (...)

    Summary Proposed by Einstein, Podolsky, and Rosen (EPR) in 1935, the entangled state has played a central part in exploring the foundation of quantum mechanics. At the end of the twentieth century, however, some physicists and mathematicians set aside the epistemological debates associated with EPR and turned it from a philosophical puzzle into practical resources for information processing. This paper examines the origin of what is known as quantum information. Scientists had considered making quantum computers (...)

    Quantum Information and Locality.Dennis Dieks - unknown
    The surprising aspects of quantum information are due to two distinctly non-classical features of the quantum world: first, different quantum states need not be orthogonal and, second, quantum states may be entangled. Non-orthogonality leads to the blurring of classical distinctions. On the other hand, entanglement leads via non-locality to teleportation and other ``entanglement-assisted'' forms of communication that go beyond what is classically possible. In this article we attempt to understand these new possibilities via an analysis (...)

    Is Measurement a Black Box? On the Importance of Understanding Measurement Even in Quantum Information and Computation.Michael Dickson - 2007 - Philosophy of Science 74 (5):1019–1032.
    It has been argued, partly from the lack of any widely accepted solution to the measurement problem, and partly from recent results from quantum information theory, that measurement in quantum theory is best treated as a black box. However, there is a crucial difference between ‘having no account of measurement' and ‘having no solution to the measurement problem'. We know a lot about measurements. Taking into account this knowledge sheds light on quantum theory as a theory (...)

  46. The Ontological Status Of Quantum Information.Robert ArnĂutu - 2010 - Studia Universitatis Babeş-Bolyai Philosophia 1.
    Quantum mechanics raise many philosophical questions regarding the status of reality. One of the newest and very important subdomain of quantum mechanics is quantum information theory. There are two questions to which a philosophical approach to quantum information has to respond: What is the referent of the concept of quantum information? and How does quantum information behaves? After a general presentation of the characteristics of quantum information as revealed (...)

    Thinking Carefully About Quantum Information.Armond Duwell - 2014 - Metascience 23 (3):485-488.
    The development of quantum information theory over the last 20 years has produced a plethora of interesting new results and along with them a host of claims have been made by physicists and philosophers about how quantum information theory helps us understand the quantum world. When one examines such claims with any attention to detail, it is quite obvious that radically different and incompatible claims are being made about the quantum world. Christopher Timpson’s (...) Information Theory and the Foundations of Quantum Mechanics provide a sober and thorough critical guide to these claims.Claims made about how quantum information theory can help us understand the quantum world are a motley collection, and so too are the chapters of Timpson’s book. That said, they can almost be sorted into two broad categories: those that aim to define quantum information and to understand the quantum world in terms of it, and those that aim to reconstruct quantum mechanics in terms of information-the ..

    Quantum Information Processing, Operational Quantum Logic, Convexity, and the Foundations of Physics.Howard Barnum - 2003 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 34 (3):343-379.
    Quantum information science is a source of task-related axioms whose consequences can be explored in general settings encompassing quantum mechanics, classical theory, and more. Quantum states are compendia of probabilities for the outcomes of possible operations we may perform on a system: ''operational states.'' I discuss general frameworks for ''operational theories'' (sets of possible operational states of a system), in which convexity plays key role. The main technical content of the paper is in a theorem that (...)

    Classical and Quantum Information: Two Kinds of Information?Cristian López & Olimpia Lombardi - 2015 - Scientiae Studia 13 (1):143-174.
    El presente artículo busca ofrecer un análisis conceptual de la noción de información, a partir del modo en que es definida por las teorías formales de Claude Shannon y de Benjamin Schumacher. Contra la postura según la cual existen dos tipos de información de naturalezas diferentes, una información clásica y una información cuántica, aquí argumentamos que no hay razones suficientes para sostener la existencia de la información cuántica como un nuevo tipo sustancialmente distinto de información. Afirmamos así que existe un (...)

    Quantum Information or Quantum Coding?Olimpia Lombardi & Cristian López - unknown
    In this work we will deal only with the concept of information in the communicational context, in which information is primarily something that has to be transmitted for communication purposes. The aim of the paper is to consider some arguments traditionally put forward to support the idea that quantum information is qualitatively different than classical information. On the basis of the analysis of those arguments, we will conclude that there are no reasons to admit the (...)
