    On Visibility in the Afshar Two-Slit Experiment.R. E. Kastner - 2009 - Foundations of Physics 39 (10):1139-1144.
    A modified version of Young’s experiment by Shahriar Afshar indirectly reveals the presence of a fully articulated interference pattern prior to the post-selection of a particle in a “which-slit” basis. While this experiment does not constitute a violation of Bohr’s Complementarity Principle as claimed by Afshar, both he and many of his critics incorrectly assume that a commonly used relationship between visibility parameter V and “which-way” parameter K has crucial relevance to his experiment. It is argued here that this relationship (...)

    The Distributive Law in the Two-Slit Experiment.P. F. Gibbins & D. B. Pearson - 1981 - Foundations of Physics 11 (9-10):797-803.
    It is shown that the lattice-theoretic distributive law does not fail to hold in the two slit-experiment for the general case offinite slit widths and for a position measurement which localizes the observed particle to afinite region of the screen. Comments are made on previous and less general discussions of the case considered.

    On the Wootters-Zurek Development of Einstein's Two-Slit Experiment.P. N. Kaloyerou - 1992 - Foundations of Physics 22 (11):1345-1377.
    We consider the compatibility of the Wootters and Zurek development of information theory as applied to the two-slit experiment with the principle of complementarity. We also consider the limitations of aspects of Wootters and Zurek's analysis, and, independently of complementarity, the extent to which Wootters and Zurek's information theory can be considered a fundamental interpretation of the quantum theory (as applied to particle-wave duality). The question of particle-wave uncertainty relations will also be taken up.

    The Afshar Two-Slit Experiment and Complementarity.Ruth Kastner - unknown
    A modified version of Young's experiment by Shahriar Afshar demonstrates that, prior to a ``which-way'' measurement indicating which slit a particle goes through, an interference pattern exists. It has been claimed that this result constitutes a violation of the Principle of Complementarity. This paper discusses the implications of this experiment and considers how Cramer's Transactional Interpretation accomodates the result. It is shown that the Afshar experiment is isomorphic in key respects to a a spin one-half particle prepared as ``spin up (...)

    From a 1D Completed Scattering and Double Slit Diffraction to the Quantum-Classical Problem for Isolated Systems.Nikolay L. Chuprikov - 2011 - Foundations of Physics 41 (9):1502-1520.
    By probability theory the probability space to underlie the set of statistical data described by the squared modulus of a coherent superposition of microscopically distinct (sub)states (CSMDS) is non-Kolmogorovian and, thus, such data are mutually incompatible. For us this fact means that the squared modulus of a CSMDS cannot be unambiguously interpreted as the probability density and quantum mechanics itself, with its current approach to CSMDSs, does not allow a correct statistical interpretation. By the example of a 1D completed scattering (...)

    Detection of Incompatible Properties in a Double-Slit Experiment.A. Sestito - 2008 - Foundations of Physics 38 (10):935-958.
    In this work we show that, within the framework of double-slit experiment, it is possible to ascertain simultaneously more incompatible properties together with the measurement of the position of the final impact-point. A wide family of solutions is concretely found and an ideal experiment realizing such a detection is designed, relatively to the detection of two incompatible properties. In the case of three incompatible properties, general conditions for the existence of solutions are singled out and a particular family of solutions (...)

    Is the Universe a Vast, Consciousness-Created Virtual Reality Simulation?Bernard Haisch - 2014 - Cosmos and History 10 (1):48-60.
    Two luminaries of 20th century astrophysics were Sir James Jeans and Sir Arthur Eddington. Both took seriously the view that there is more to reality than the physical universe and more to consciousness than simply brain activity. In his Science and the Unseen World Eddington speculated about a spiritual world and that "conscious is not wholly, nor even primarily a device for receiving sense impressions." Jeans also speculated on the existence of a universal mind and a non-mechanical reality, writing in (...)

    Light as a Solution to Puzzles Aboutlight.David Grandy - 2002 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 33 (2):369-379.
    Light is puzzling in modern physics–witness wave-particle duality, the two-slit experiment, and the invariant speed of light. These puzzles are not intrinsic to light but arise from overly narrow views of light. Disregarding the expansive, unitary nature of light that informs everyday experience, modern physics treats light as if it were self-bounded and separable. Further, physics assumes that light is not complicit with observations of light, that the two are separable. By likening light to light-illuminated entities, these attitudes set the (...)

    Investigating Puzzling Aspects of the Quantum Theory by Means of Its Hydrodynamic Formulation.A. S. Sanz - 2015 - Foundations of Physics 45 (10):1153-1165.
    Bohmian mechanics, a hydrodynamic formulation of the quantum theory, constitutes a useful tool to understand the role of the phase as the mechanism responsible for the dynamical evolution displayed by quantum systems. This role is analyzed and discussed here in the context of quantum interference, considering to this end two well-known scenarios, namely Young’s two-slit experiment and Wheeler’s delayed choice experiment. A numerical implementation of the first scenario is used to show how interference in a coherent superposition of two counter-propagating (...)

    Three Slit Experiments and the Structure of Quantum Theory.Cozmin Ududec, Howard Barnum & Joseph Emerson - 2011 - Foundations of Physics 41 (3):396-405.
    In spite of the interference manifested in the double-slit experiment, quantum theory predicts that a measure of interference defined by Sorkin and involving various outcome probabilities from an experiment with three slits, is identically zero. We adapt Sorkin’s measure into a general operational probabilistic framework for physical theories, and then study its relationship to the structure of quantum theory. In particular, we characterize the class of probabilistic theories for which the interference measure is zero as ones in which it is (...)

    A Double‐Slit Experiment for Non‐Classical Interference Effects in Decision Making.Pierfrancesco La Mura - 2014 - Topics in Cognitive Science 6 (1):58-62.
    We discuss the possible nature and role of non-physical entanglement, and the classical vs. non-classical interface, in models of human decision-making. We also introduce an experimental setting designed after the double-slit experiment in physics, and discuss how it could be used to discriminate between classical and non-classical interference effects in human decisions.

  14. Non-Kolmogorovian Approach to the Context-Dependent Systems Breaking the Classical Probability Law.Masanari Asano, Irina Basieva, Andrei Khrennikov, Masanori Ohya & Ichiro Yamato - 2013 - Foundations of Physics 43 (7):895-911.
    There exist several phenomena breaking the classical probability laws. The systems related to such phenomena are context-dependent, so that they are adaptive to other systems. In this paper, we present a new mathematical formalism to compute the joint probability distribution for two event-systems by using concepts of the adaptive dynamics and quantum information theory, e.g., quantum channels and liftings. In physics the basic example of the context-dependent phenomena is the famous double-slit experiment. Recently similar examples have been found in biological (...)

    The Double-Slit Experiment: A Paradox-Free Kinematic Description.Alexey Kryukov - unknown
    The paradoxes of the double-slit experiment with an electron are shown to originate in the implicit assumption that the electron is always located in the classical space. It is demonstrated that there exists a natural substitute for this assumption that provides a method of resolving the paradoxes.

    The Two-Prism Experiment and Wave-Particle Duality of Light.Partha Ghose & Dipankar Home - 1996 - Foundations of Physics 26 (7):943-953.
    A number of papers on wave-particle duality has appeared since the two-prism experiment was performed by Mizobuchi and Ohtake, based on a suggestion by Ghose, Home, and Agarwal. Against this backdrop, the present paper provides further clarification of the key issues involved in the analysis of the two-prism experiment. In the process, we present an overview of wave-particle duality vis-a vis Bohr's complementarity principle.

    De Broglian Probabilities in the Double-Slit Experiment.M. Božić, Z. Marić & J. P. Vigier - 1992 - Foundations of Physics 22 (11):1325-1344.
    A new probability interpretation of interference phenomena in the double-slit experiment is proposed. It differs from the standard interpretation (based on elementary events happening in complementary, mutually exclusive setups—arrivals of waves to the screen when one of the slits is closed) which encounters the “paradox” that the law of total probability is violated. This new interpretation is free of such difficulties and paradoxes since it is based on compatible elementary events (events happening in the same setup in which happenall events (...)

    Three-Slit Experiments and Quantum Nonlocality.Gerd Niestegge - 2013 - Foundations of Physics 43 (6):805-812.
    An interesting link between two very different physical aspects of quantum mechanics is revealed; these are the absence of third-order interference and Tsirelson’s bound for the nonlocal correlations. Considering multiple-slit experiments—not only the traditional configuration with two slits, but also configurations with three and more slits—Sorkin detected that third-order (and higher-order) interference is not possible in quantum mechanics. The EPR experiments show that quantum mechanics involves nonlocal correlations which are demonstrated in a violation of the Bell or CHSH inequality, but (...)

  19. Manifestation of Quantum Mechanical Properties of a Proprietor’s Consciousness in Slit Measurements of Economic Systems.Sergiy Melnyk & Igor Tuluzov - 2014 - Neuroquantology 12 (3).
    The present paper discusses the problem of quantum-mechanical properties of a subject’s consciousness. The model of generalized economic measurements is used for the analysis. Two types of such measurements are analyzed – transactions and technologies. Algebraic ratios between the technology-type measurements allow making their analogy with slit experiments in physics. It has been shown that the description of results of such measurements is possible both in classical and in quantum formalism of calculation of probabilities. Thus, the quantum-mechanical formalism of the (...)

    The Observer in the Quantum Experiment.Bruce Rosenblum & Fred Kuttner - 2002 - Foundations of Physics 32 (8):1273-1293.
    A goal of most interpretations of quantum mechanics is to avoid the apparent intrusion of the observer into the measurement process. Such intrusion is usually seen to arise because observation somehow selects a single actuality from among the many possibilities represented by the wavefunction. The issue is typically treated in terms of the mathematical formulation of the quantum theory. We attempt to address a different manifestation of the quantum measurement problem in a theory-neutral manner. With a version of the two-slit (...)

    Two Studies Concerning the Michelson-Morley Experiment.Håkan Törnebohm - 1970 - Foundations of Physics 1 (1):47-56.
    In the first of these two studies it is argued that the discrepancy between the predicted and actual outcome of the Michelson-Morley experiment is due to the use of Newton's velocity addition theorem in conjunction with an electromagnetic theory of light. The ether hypothesis is not directly affected at all. The second study is a case study of the removal of a clash in physics generated from the outcome of an experiment. The clash due to the Michelson-Morley experiment gave rise (...)

    Improving Survey Completion Rates and Sample Representativeness Using Highly-Interesting Questions: A National Panel Experiment Comparing One and Two Stage Questions.Jared M. Hansen, Scott Smith & Michael D. Geurts - unknown
    In this article, the insertion of a two-staged highly interesting question in an online, survey-based field experiment is shown to produce better survey completion rate (i.e., decreases completion refusal by 8%) and sample representativeness (increases the number of moderate answer patterns by 12%) than a typical (same) highly interesting question at the beginning of a survey only. Using nonparametric tests and subgroup probability analysis, measured effects include survey completion rates, response bias and reported demographic differences. In regards to sample representativeness, (...)

    On Quantum Propensities: Two Arguments Revisited.Mauricio Suárez - 2004 - Erkenntnis 61 (1):1-16.
    Peter Milne and Neal Grossman have argued against Popper's propensity interpretation of quantum mechanics, by appeal to the two-slit experiment and to the distinction between mixtures and superpositions, respectively. In this paper I show that a different propensity interpretation successfully meets their objections. According to this interpretation, the possession of a quantum propensity by a quantum system is independent of the experimental set-ups designed to test it, even though its manifestations are not.

    Unsharp Particle-Wave Duality in a Photon Split-Beam Experiment.P. Mittelstaedt, A. Prieur & R. Schieder - 1987 - Foundations of Physics 17 (9):891-903.
    In a quantum mechanical two-slit experiment one can observe a single photon simultaneously as particle (measuring the path) and as wave (measuring the interference pattern) if the path and the interference pattern are measured in the sense of unsharp observables. These theoretical predictions are confirmed experimentally by a photon split-beam experiment using a modified Mach—Zehnder interferometer.

    On the Measurement Problem for a Two-Level Quantum System.Alexey Kryukov - 2007 - Foundations of Physics 37 (1):3-39.
    A geometric approach to quantum mechanics with unitary evolution and non-unitary collapse processes is developed. In this approach the Schrödinger evolution of a quantum system is a geodesic motion on the space of states of the system furnished with an appropriate Riemannian metric. The measuring device is modeled by a perturbation of the metric. The process of measurement is identified with a geodesic motion of state of the system in the perturbed metric. Under the assumption of random fluctuations of the (...)

    Replacing the Singlet Spinor of the EPR-B Experiment in the Configuration Space with Two Single-Particle Spinors in Physical Space.Michel Gondran & Alexandre Gondran - 2016 - Foundations of Physics 46 (9):1109-1126.
    Recently, for spinless non-relativistic particles, Norsen and Norsen et al. show that in the de Broglie–Bohm interpretation it is possible to replace the wave function in the configuration space by single-particle wave functions in physical space. In this paper, we show that this replacment of the wave function in the configuration space by single-particle functions in the 3D-space is also possible for particles with spin, in particular for the particles of the EPR-B experiment, the Bohm version of the Einstein–Podolsky–Rosen experiment.

Contours of the reduced action, trajectories and loci of transit times are developed in the region near the two point sources. The trajectory through any point in Euclidean 3-space also passes simultaneously through both point sources.

  46. Delayed-Choice Experiments and the Metaphysics of Entanglement.Matthias Egg - unknown
    Delayed-choice experiments in quantum mechanics are often taken to undermine a realistic interpretation of the quantum state. More specifically, Healey has recently argued that the phenomenon of delayed-choice entanglement swapping is incompatible with the view that entanglement is a physical relation between quantum systems. This paper argues against these claims. It first reviews two paradigmatic delayed-choice experiments and analyzes their metaphysical implications. It then applies the results of this analysis to the case of entanglement swapping, showing that such experiments pose (...)

    The Role of Decoherence in Quantum Mechanics.Guido Bacciagaluppi - 2008 - Stanford Encyclopedia of Philosophy.
    Interference phenomena are a well-known and crucial feature of quantum mechanics, the two-slit experiment providing a standard example. There are situations, however, in which interference effects are (artificially or spontaneously) suppressed. We shall need to make precise what this means, but the theory of decoherence is the study of (spontaneous) interactions between a system and its environment that lead to such suppression of interference. This study includes detailed modelling of system-environment interactions, derivation of equations (‘master equations’) for the (reduced) state (...)

    Classical Physics and the Actualization of Quantum Pure Possibilities.Amihud Gilead - unknown
    This paper differs from any previous view in discussing quantum pure possibilities as individuals, existing independently of any observer or mind. These pure possibilities are also absolutely independent of any metaphysical or logical view that endorses the notion of possible worlds. In my view, the relationship between quantum possibilities and classical physical reality is not between reality as such, as it is in itself, and its phenomena. It is rather between fundamental or primary reality, consisting of quantum pure possibilities, on (...)

    Higher-Order Interference in Extensions of Quantum Theory.Ciarán M. Lee & John H. Selby - 2017 - Foundations of Physics 47 (1):89-112.
    Quantum interference, manifest in the two slit experiment, lies at the heart of several quantum computational speed-ups and provides a striking example of a quantum phenomenon with no classical counterpart. An intriguing feature of quantum interference arises in a variant of the standard two slit experiment, in which there are three, rather than two, slits. The interference pattern in this set-up can be written in terms of the two and one slit patterns obtained by blocking one, or more, of the (...)

    Nonseparable Processes and Causal Explanation.Richard Healey - 1994 - Studies in History and Philosophy of Science Part A 25 (3):337-374.
    If physical reality is nonseparable, as quantum mechanics suggests, then it may contain processes of a quite novel kind. Such nonseparable processes could connect space-like separated events without violating relativity theory or any defensible locality condition. Appeal to nonseparable processes could ground theoretical explanations of such otherwise puzzling phenomena as the two-slit experiment, and EPR- type correlations. We find such phenomena puzzling because they threaten cherished conceptions of how causes operate to produce their effects. But nonseparable processes offer us an (...)
