5Quasiset theory: a formal approach to a quantum ontology of propertiesSynthese 200 (5): 126. 2022.In previous works, an ontology of properties for quantum mechanics has been proposed, according to which quantum systems are bundles of properties with no principle of individuality. The aim of the present article is to show that, since quasiset theory is particularly suited for dealing with aggregates of items that do not belong to the traditional category of individual, it supplies an adequate metalanguage to speak of the proposed ontology of properties and its structure.

6What is Quantum Information? (edited book)CUP. 2017.Combining physics and philosophy, this is a uniquely interdisciplinary examination of quantum information science. Suitable as both a discussion of the conceptual and philosophical problems of this field and a comprehensive standalone introduction, this book will benefit both experienced and new researchers in quantum information and the philosophy of physics.

173What is Shannon information?Synthese 193 (7): 19832012. 2016.Despite of its formal precision and its great many applications, Shannon’s theory still offers an active terrain of debate when the interpretation of its main concepts is the task at issue. In this article we try to analyze certain points that still remain obscure or matter of discussion, and whose elucidation contribute to the assessment of the different interpretative proposals about the concept of information. In particular, we argue for a pluralist position, according to which the different …Read more

12Classical limit and quantum logicInternational Journal of Theoretical Physics 57. 2018.The more common scheme to explain the classical limit of quantum mechanics includes decoherence, which removes from the state the interference terms classically inadmissible since embodying nonBooleanity. In this work we consider the classical limit from a logical viewpoint, as a quantumtoBoolean transition. The aim is to open the door to a new study based on dynamical logics, that is, logics that change over time. In particular, we appeal to the notion of hybrid logics to describe semiclassi…Read more

73Logic, Geometry And Probability TheorySOP Transactions On Theoretical Physics 1. 2013.We discuss the relationship between logic, geometry and probability theory under the light of a novel approach to quantum probabilities which generalizes the method developed by R. T. Cox to the quantum logical approach to physical theories.

40What is quantum information?Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 56 1726. 2016.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 nonorthogonal 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 information that bec…Read more

149Qspaces and the Foundations of Quantum MechanicsFoundations of Physics 38 (11): 969994. 2008.Our aim in this paper is to take quite seriously Heinz Post’s claim that the nonindividuality and the indiscernibility of quantum objects should be introduced right at the start, and not made a posteriori by introducing symmetry conditions. Using a different mathematical framework, namely, quasiset theory, we avoid working within a labeltensorproductvectorspaceformalism, to use Redhead and Teller’s words, and get a more intuitive way of dealing with the formalism of quantum mechanics, alt…Read more

9On the interpretation of probabilities in generalized probabilistic modelsIn José Acacio de Barros, Bob Coecke & E. Pothos (eds.), Quantum Interaction. QI 2016. Lecture Notes in Computer Science, Vol. 10106, Springer, Cham. pp. 194205. 2016.We discuss generalized pobabilistic models for which states not necessarily obey Kolmogorov's axioms of probability. We study the relationship between properties and probabilistic measures in this setting, and explore some possible interpretations of these measures.

3Nonunitary evolution of quantum logicsIn F. Bagarello, R. Passante & C. Trapani (eds.), NonHermitian Hamiltonians in Quantum Physics. Springer Proceedings in Physics, vol 184, Springer, Cham. pp. 219234. 2016.In this work we present a dynamical approach to quantum logics. By changing the standard formalism of quantum mechanics to allow nonHermitian operators as generators of time evolution, we address the question of how can logics evolve in time. In this way, we describe formally how a nonBoolean algebra may become a Boolean one under certain conditions. We present some simple models which illustrate this transition and develop a new quantum logical formalism based in complex spectral resolutions,…Read more

26Quantum Logical Structures For Identical ParticlesCadernos de História E Filosofia da Ciéncia 2 (1): 1358. 2016.In this work we discuss logical structures related to indistinguishable particles. Most of the framework used to develop these structures was presented in [17, 28] and in [20, 14, 15, 16]. We use these structures and constructions to discuss possible ontologies for identical particles. In other words, we use these structures in order to characterize the logical structure of quantum systems for the case of indistinguishable particles, and draw possible philosophical implications. We also review s…Read more

47A Discussion on Particle Number and Quantum IndistinguishabilityFoundations of Physics 37 (6): 855878. 2007.The concept of individuality in quantum mechanics shows radical differences from the concept of individuality in classical physics, as E. Schrödinger pointed out in the early steps of the theory. Regarding this fact, some authors suggested that quantum mechanics does not possess its own language, and therefore, quantum indistinguishability is not incorporated in the theory from the beginning. Nevertheless, it is possible to represent the idea of quantum indistinguishability with a firstorder la…Read more

15A new conceptual scheme for the interpretation of the improper mixtures in quantum mechanicsScientiae Studia 11 (1): 101118. 2013.En este artículo, analizamos el significado de las matrices densidad en el formalismo de la mecánica cuántica. Discutimos el problema de los "sistemas cuánticos compuestos" en la lógica cuántica así como también la interpretación de las mezclas impropias. Tomando en cuenta el desarrollo de la lógica cuántica convexa, presentamos un análisis de la estructura formal de la teoría que, argumentaremos, debe ser considerado a la hora de desarrollar un nuevo esquema conceptual para la interpretación de…Read more

49A formal framework for the study of the notion of undefined particle number in quantum mechanicsSynthese 192 (2): 505523. 2015.It is usually stated that quantum mechanics presents problems with the identity of particles, the most radical position—supported by E. Schrödinger—asserting that elementary particles are not individuals. But the subject goes deeper, and it is even possible to obtain states with an undefined particle number. In this work we present a set theoretical framework for the description of undefined particle number states in quantum mechanics which provides a precise logical meaning for this notion. Thi…Read more
