Preface
No full textThe special issue ‘Quantum Foundations & Quantum Information (QF&QI)-13’ contains a representative selection of papers given at the 15th Växjö conference on Quantum Foundations, held 10–13 June 2013. This important event in the development of foundational understanding of quantum theory and experiment combined the Marcus Wallenberg symposium ‘Quantum Theory: Advances and Problems’ (QTAP) and its satellite workshop QF&QI. As previous Växjö con- ferences, QTAP/ QF&QI was arranged by the International Centre for Mathe- matical Modeling in Physics, Engineering and Cognitive Sciences, Linnaeus University, Sweden. The organizing committees of QTPA and QF&QI consisted of leading theoreticians and experimentalists, and philosophers with strong interest in quantum foundations

“Something happened:” on the real, the actual, and the virtual in elementary particle physics
No full textThroughout the history of quantum theory, “an elementary particle” has been a problem to which only fragments of a possible solution could be offered. At a certain point of this history, “a virtual particle” has become part of this problem. While still considering this problem as a problem, this article, in contrast to most approaches to it, which are realist in nature, offers a nonrealist one. This approach is grounded in the concept of reality without realism, RWR, introduced by this author previously, and an interpretation of high-energy quantum phenomena and quantum field theory (QFT), grounded in this concept, which allows for a range of (RWR-type) interpretations. The status of real and virtual particles is different in the present interpretation. While, in this interpretation, both concepts are idealizations, that of real particles is required by it. By contrast, the concept of virtual particles is not required, although, because of certain observable effects in high-energy quantum regimes, this interpretation assumes that there exists something in nature, especially manifested in high-energy quantum regimes, that may be handled by means of the concept of virtual particles. RWR-type interpretations do, however, permit an idealization defined by this concept and may adopt it, because of its practical effectiveness. This article will do so, while still maintaining the essential difference in the nature of the idealizations defined by the concepts of real and virtual particles
Reality, Indeterminacy, Probability, and Information in Quantum Theory
No full textFollowing the view of several leading quantum-information theorists, this paper argues that quantum phenomena, including those exhibiting quantum correlations (one of their most enigmatic features), and quantum mechanics may be best understood in quantum-informational terms. It also argues that this understanding is implicit already in the work of some among the founding figures of quantum mechanics, in particular W. Heisenberg and N. Bohr, half a century before quantum information theory emerged and confirmed, and gave a deeper meaning to, to their insights. These insights, I further argue, still help this understanding, which is the main reason for considering them here. My argument is grounded in a particular interpretation of quantum phenomena and quantum mechanics, in part arising from these insights as well. This interpretation is based on the concept of reality without realism, RWR (which places the reality considered beyond representation or even conception), introduced by this author previously, in turn, following Heisenberg and Bohr, and in response to quantum information theory
The Maze of Taste: On Bataille, Derrida, and Kant
Get PDFThe case of Kant's Critique of Judgment offers a powerful example of the radical disruption of the metaphysical text, enacted by Bataille's major сoncepts. The analysis of the metaphor of economy in Kant, Bataille and Derrida suggests the crucial importance of Bataille's general economy— as the economy of loss —for deconstructing the Kantian conception of genius and the whole scheme of taste— as an economy of consumption —and inscribing a complex interplay forces that the general economy is designed to account for. Once however taste, art and the economy of genius can no longer be inscribed through the restricted economy of the metaphysical text, the question of genre and style of a different inscription—a general economy—acquires a crucial significance. Bataille's own discursive practice can be seen as an exemplification of such a different— plural — style
1925. “Atomic Theory and Mechanics”: From the Old Quantum Theory to Heisenberg’s Quantum Mechanics
No full textA Missing Link: The Double-Slit Experiment and Quantum Entanglement
No full textThis article reconsiders the double-slit experiment by establishing a new type of relationship between it and the concept of entanglement. While the role of entanglement in the double-slit experiment has been considered, this particular relationship appears to have been missed in preceding discussions of the experiment, even by Bohr, who extensively used it to support his argument concerning quantum physics. The main reason for this relationship is the different roles of the diaphragm with slits in two setups, S1 and S2, defining the double-slit experiment as a quantum experiment. In S1, in each individual run of the experiment one can in principle (even if not actually) know throughout which slit the quantum object considered has passed; in S2 this knowledge is in principle impossible, which impossibility is coextensive with the appearance of the interference pattern, once a sufficient number of individual runs of the experiment have taken place. The article offers the following argument based on two new concepts, an “experimentally quantum object” and an “ontologically quantum object.” In S1 the diaphragm can be treated as part of an observational arrangement and thus considered as a classical object, while the object passing through one or the other slit is considered as an “ontologically quantum object,” defined as an object necessary to establish a quantum phenomenon. By contrast, in S2, the diaphragm can, via the concept of Heisenberg-von-Neumann cut, be treated as an “experimentally quantum object,” defined as an object treatable by quantum theory, even while possibly being an ontologically classical object. This interaction is not an observation but a quantum entanglement between these two quantum objects, one ontologically and one experimentally quantum. This argument is grounded in a particular interpretation of quantum phenomena and quantum theory, which belongs to the class of interpretations designated here as “reality without realism” (RWR) interpretations. The article also argues that wave-particle complementarity, with which the concept of complementarity is often associated, plays little, if any, role in quantum physics, or in Bohr’s thinking, and may be misleading in considering the double-slit experiment, often explained by using this complementarity
