Interpreting the Modal Kochen-Specker Theorem: Possibility and Many Worlds in Quantum Mechanics
No full textIn this paper we attempt to physically interpret the Modal Kochen-Specker (MKS) theorem. In order to do so, we analyze the features of the possible properties about quantum systems arising from the elements in an orthomodular lattice and distinguish the use of “possibility” in the classical and quantum formalisms. Taking into account the modal and many worlds non-collapse interpretation of the projection postulate, we discuss how the MKS theorem rules the constrains to actualization, and thus, the relation between actual and possible realms
Many worlds and modality in the interpretation of quantum mechanics: an algebraic approach
No full textMany worlds interpretations (MWI) of quantum mechanics avoid the measurement problem by considering every term in the quantum superposition as actual. A seemingly opposed solution is proposed by modal interpretations (MI) which state that quantum mechanics does not provide an account of what ?actually is the case?, but rather deals with what ?might be the case?, i.e. with possibilities. In this paper we provide an algebraic framework which allows us to analyze in depth the modal aspects of MWI. Within our general formal scheme we also provide a formal comparison between MWI and MI, in particular, we provide a formal understanding of why ?even though both interpretations share the same formal structure? MI fall pray of Kochen-Specker (KS) type contradictions while MWI escape them.Fil: Domenech, Graciela. Consejo Nacional de Investigaciónes Científicas y Técnicas.

Interpretaciones modales y de muchos mundos de la mecánica cuántica: un análisis de las propiedades físicas
No full textQuantum probability: a reliable tool for an agent or a reliable source of reality?
No full textIn this paper we attempt to analyze the concept of quantum probability within quantum computation and quantum computational logic. While the subjectivist interpretation of quantum probability explains it as a reliable predictive tool for an agent in order to compute measurement outcomes, the objectivist interpretation understands quantum probability as providing reliable information of a real state of affairs. After discussing these different viewpoints we propose a particular objectivist interpretation grounded on the idea that the Born rule provides information about an intensive realm of reality. We then turn our attention to the way in which the subjectivist interpretation of probability is presently applied within both quantum computation and quantum computational logic. Taking as a standpoint our proposed intensive account of quantum probability we discuss the possibilities and advantages it might open for the modeling and development of both quantum computation and quantum computational logic
Equational characterization for two-valued states in orthomodular quantum systems
No full textIn this paper we develop an algebraic framework in which several classes of two-valued
states over orthomodular lattices may be equationally characterized. The class of two-valued
states and the subclass of Jauch–Piron two-valued states are among the classes which we stud
Where are the Pink and White Terraces of Lake Rotomahana?
No full textIn 2018, Bunn and Nolden published a paper purporting to have established the true position of the Pink and White Terraces of Lake Rotomahana using forensic cartography, ‘reverse engineering’ an 1859 compass survey of Ferdinand von Hochstetter. Their results suggest that the terraces are buried partly on land, near the present-day lake shore. Sightlines constructed using an 1881 Charles Spencer photograph overlooking the White Terraces towards distant Maungaongaonga and Maungakakaramea, and replicated by us, show the location of the White Terraces by Bunn and Nolden to be untenable. Fitting the pre-1886 eruption outline map of Lake Rotomahana of Keam (2016. The Tarawera eruption, Lake Rotomahana, and the origin of the Pink and White Terraces. Journal of Volcanology and Geothermal Research 314:10–38.) to our high-resolution bathymetry shows a remarkable fit of the shoreline around the Pink Terraces area to distinct bathymetric features. Side-scan sonar images of inferred tiers of Pink Terraces (de Ronde CEJ, Scott BJ, Leonard GS, Calvert AT. 2016a. Evolution of the sublacustrine geothermal system of Lake Rotomahana, New Zealand: effects of the 1886 Mt. Tarawera eruption—an introduction. Journal of Volcanology and Geothermal Research 314:1–9.) show they sit where the map of Keam would have them lie.</p
Representing Quantum Superpositions: Powers, Potentia and Potential Effectuations
No full textIn this paper we attempt to provide a physical representation of quantum superpositions. For this purpose we discuss the constraints of the quantum formalism to the notion of possibility and the necessity to consider a potential realm independent of actuality. Taking these insights into account and from the basic principles of quantum mechanics itself we advance towards the definition of the notions of power and potentia. Assuming these notions as a standpoint we analyze the meaning of ‘observation’ and ‘interaction’. As a conclusion we provide a set of axioms which comprise our interpretation of quantum mechanics and argue in favor of a redefinition of the orthodox problems discussed in the literature
