    Can We Falsify the Consciousness-Causes-Collapse Hypothesis in Quantum Mechanics?Jos’E. Ac’Acio de Barros & Gary Oas - 2017 - Foundations of Physics 47 (10):1294-1308.
    In this paper we examine some proposals to disprove the hypothesis that the interaction between mind and matter causes the collapse of the wave function, showing that such proposals are fundamentally flawed. We then describe a general experimental setup retaining the key features of the ones examined, and show that even a more general case is inadequate to disprove the mind-matter collapse hypothesis. Finally, we use our setup provided to argue that, under some reasonable assumptions about consciousness, such hypothesis is (...)

    Ontological indistinguishability as a central tenet of quantum theory.José Acacio de Barros & Federico Holik - 2023 - Philosophical Transactions of the Royal Society A 381:20220100.
    Quantum indistinguishability directly relates to the philosophical debate on the notions of identity and individuality. They are crucial for our understanding of multipartite quantum systems. Furthermore, the correct interpretation of this feature of quantum theory has implications that transcend fundamental science and philosophy, given that quantum indistinguishability is a resource in quantum information theory. Most of the conceptual analysis of quantum indistinguishability is restricted to studying the permutational invariance of quantum states, the concomitant quantum statistics and their entanglement. Here, we (...)

  3. Where Does Quanta Meet Mind?Carlos Montemayor & J. de Barros - 2019 - In J. De Barros & Carlos Montemayor (eds.), Quanta and Mind. Springer Verlag.
    The connection between quantum physics and the mind has been debated for almost a hundred years. There are several proposals as to how quantum effects might be relevant to understanding consciousness, including von Neumann’s Consciousness Causes Collapse interpretation (CCC), Penrose’s Orchestrated objective reduction (Orch OR), Atmanspacher quantum emergence theory, or Vitiello’s field theory. In this paper, we examine the CCC, in particular Stapp’s theory of interaction of mind and matter, and discuss how this imposes constraints to possible brain structures. We (...)

    Quanta and Mind: Essays on the Connection Between Quantum Mechanics and Consciousness.J. Acacio de Barros & Carlos Montemayor (eds.) - 2019 - Springer Verlag.
    This edited volume examines aspects of the mind/consciousness that are relevant to the interpretations of quantum mechanics. In it, an international group of contributors focus on the possible connections between quantum mechanics and consciousness. They look at how consciousness can help us with quantum mechanics as well as how quantum mechanics can contribute to our understanding of consciousness. For example, what do different interpretations aimed at solving the measurement problem in quantum mechanics tell us about the nature of consciousness, such (...)

    Implementation, Formalization, and Representation: Challenges for Integrated Information Theory.C. Montemayor, J. A. de Barros & L. P. G. De Assis - 2019 - Journal of Consciousness Studies 26 (1-2):107-132.
    Any theory of information needs to comply with what we call the implementation, formalization, and representation constraints. These constraints are justified by basic considerations concerning scientific modelling and methodology. In the first part of this paper, we argue that the implementation and formalization constraints cannot be satisfied because the relation between Shannon information and IIT must be clarified. In the second part of the paper, we focus on the representation constraint. We argue that IIT cannot succeed in satisfying this constraint (...)

  6. Indistinguishability and the origins of contextuality in physics.José Acacio De Barros, Federico Holik & Décio Krause - 2019 - Philosophical Transactions of the Royal Society A 377 (2157): 20190150.
    In this work, we discuss a formal way of dealing with the properties of contextual systems. Our approach is to assume that properties describing the same physical quantity, but belonging to different measurement contexts, are indistinguishable in a strong sense. To construct the formal theoretical structure, we develop a description using quasi-set theory, which is a set-theoretical framework built to describe collections of elements that violate Leibnitz's principle of identity of indiscernibles. This framework allows us to consider a new ontology (...)

  7. Contextuality in the Integrated Information Theory.J. Acacio de Barros, Carlos Montemayor & Leonardo De Assis - forthcoming - In J. A. de Barros, B. Coecke & E. Pothos (eds.), Lecture Notes on Computer Science.
    Integrated Information Theory (IIT) is one of the most influential theories of consciousness, mainly due to its claim of mathematically formalizing consciousness in a measurable way. However, the theory, as it is formulated, does not account for contextual observations that are crucial for understanding consciousness. Here we put forth three possible difficulties for its current version, which could be interpreted as a trilemma. Either consciousness is contextual or not. If contextual, either IIT needs revisions to its axioms to include contextuality, (...)

    Probabilistic Inequalities And Upper Probabilities In Quantum Mechanical Entanglement.J. De Barros & Patrick Suppes - 2010 - Manuscrito 33 (1):55-71.
    In this paper we analyze the existence of joint probabilities for the Bell-type and GHZ entangled states. We then propose the usage of nonmonotonic upper probabilities as a tool to derive consistent joint upper probabilities for the contextual hidden variables. Finally, we show that for the extreme example of no error, the GHZ state allows for the definition of a joint upper probability that is consistent with the strong correlations.

    Constraining Meanings With Contextuality.J. Acacio de Barros, Carlos Montemayor, Leonardo P. G. De Assis, Paul Skokowsi & John Perry - forthcoming - Foundations of Science:1-21.
    In this paper, we defend two claims. First, we argue that a notion of contextuality that has been formalized in physics and psychology is applicable to linguistic contexts. Second, we propose that this formal apparatus is philosophically significant for the epistemology of language because it imposes homogeneous rational constraints on speakers. We propose a Contextuality Principle that explains and articulates these two claims. This principle states that speakers update contextual information by significantly reducing the space of probabilities and variables in (...)

    Two questions on the geometry of gauge fields.N. C. A. da Costa, F. A. Doria, A. F. Furtado-do-Amaral & J. A. de Barros - 1994 - Foundations of Physics 24 (5):783-800.
    We first show that a theorem by Cartan that generalizes the Frobenius integrability theorem allows us (given certain conditions) to obtain noncurvature solutions for the differential Bianchi conditions and for higher-degree similar relations. We then prove that there is no algorithmic procedure to determine, for a reasonable restricted algebra of functions on spacetime, whether a given connection form satisfies the preceding conditions. A parallel result gives a version of Gödel's first incompleteness theorem within an (axiomatized) theory of gauge fields.

    In this paper we study in details a system of two weakly coupled harmonic oscillators from the point of view of Bohm’s interpretation of quantum mechanics. This system may be viewed as a simple model for the interaction between a photon and a photodetector. We obtain exact solutions for the general case. We then compute approximate solutions for the case where one oscillator is initially in its first excited state (a single photon) reaching the other oscillator in its ground state (...)
