    Individuality, Quasi-Sets and the Double-Slit Experiment.Adonai S. Sant'Anna - forthcoming - Quantum Studies: Mathematics and Foundations.
    Quasi-set theory $\cal Q$ allows us to cope with certain collections of objects where the usual notion of identity is not applicable, in the sense that $x = x$ is not a formula, if $x$ is an arbitrary term. $\cal Q$ was partially motivated by the problem of non-individuality in quantum mechanics. In this paper I discuss the range of explanatory power of $\cal Q$ for quantum phenomena which demand some notion of indistinguishability among quantum objects. My main focus 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.

    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 (...)

    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 (...)

    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.

    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 (...)

    Theoretical Intricacies of the Single-Slit, the Double-Slit, and Related Experiments in Quantum Mechanics.Edward B. Manoukian - 1989 - Foundations of Physics 19 (5):479-504.
    The purpose of this work is to carry out a systematic, detailed analytical study, together with the direct interpretations, as they follow from the analytical expressions obtained, of three basic “experiments” which have been classical examples in our understanding of quantum mechanics. The experiments considered are: the single- and double-slit (-hole) experiments, and the final one, which, in particular, deals with the situation where a particle is “reflected off” the detection screen in the single-slit experiment. Special emphasis is (...)

    Quantum Mechanics Over Sets.David Ellerman - forthcoming - Synthese.
    This paper shows how the classical finite probability theory (with equiprobable outcomes) can be reinterpreted and recast as the quantum probability calculus of a pedagogical or toy model of quantum mechanics over sets (QM/sets). There have been several previous attempts to develop a quantum-like model with the base field of ℂ replaced by ℤ₂. Since there are no inner products on vector spaces over finite fields, the problem is to define the Dirac brackets and the probability calculus. The previous attempts (...)

  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 (...)

    Paradox in Wave-Particle Duality.Shahriar S. Afshar, Eduardo Flores, Keith F. McDonald & Ernst Knoesel - 2007 - Foundations of Physics 37 (2):295-305.
    We report on the simultaneous determination of complementary wave and particle aspects of light in a double-slit type “welcher-weg” experiment beyond the limitations set by Bohr’s Principle of Complementarity. Applying classical logic, we verify the presence of sharp interference in the single photon regime, while reliably maintaining the information about the particular pinhole through which each individual photon had passed. This experiment poses interesting questions on the validity of Complementarity in cases where measurements techniques that avoid Heisenberg’s (...)

    Double-Slit Interference and Temporal Topos.Goro Kato & Tsunefumi Tanaka - 2006 - Foundations of Physics 36 (11):1681-1700.
    The electron double-slit interference is re-examined from the point of view of temporal topos. Temporal topos (or t-topos) is an abstract algebraic (categorical) method using the theory of sheaves. A brief introduction to t-topos is given. When the structural foundation for describing particles is based on t-topos, the particle-wave duality of electron is a natural consequence. A presheaf associated with the electron represents both particle-like and wave-like properties depending upon whether an object in the site (t-site) is specified (particle-like) (...)

    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 (...)

    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 (...)

    Complementarity Paradox Solved: Surprising Consequences. [REVIEW]E. V. Flores & J. M. De Tata - 2010 - Foundations of Physics 40 (11):1731-1743.
    Afshar et al. claim that their experiment shows a violation of the complementarity inequality. In this work, we study their claim using a modified Mach-Zehnder setup that represents a simpler version of the Afshar experiment. We find that our results are consistent with Afshar et al. experimental findings. However, we show that within standard quantum mechanics the results of the Afshar experiment do not lead to a violation of the complementarity inequality. We show that their claim originates (...)

  20. Delayed-Choice Experiments and the Metaphysics of Entanglement.Matthias Egg - 2013 - Foundations of Physics 43 (9):1124-1135.
    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 (...)

    On the Necessity of Including the Observer in Physical Theory.Wolfgang Baer - 2015 - Cosmos and History 11 (2):160-174.
    All statements describing physical reality are derived through interpretation of measurement results that requires a theory of the measuring instruments used to make the measurements. The ultimate measuring instrument is our body which displays its measurement results in our mind. Since a physical theory of our mind-body is unknown, the correct interpretation of its measurement results is unknown. The success of the physical sciences has led to a tendency to treat assumption in physics as indisputable facts. This tendency hampers the (...)

    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 (...)

    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.

    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.

    Double-Slit Interference Pattern for a Macroscopic Quantum System.Hamid Reza Naeij & Afshin Shafiee - 2016 - Foundations of Physics 46 (12):1634-1648.
    In this study, we solve analytically the Schrödinger equation for a macroscopic quantum oscillator as a central system coupled to two environmental micro-oscillating particles. Then, the double-slit interference patterns are investigated in two limiting cases, considering the limits of uncertainty in the position probability distribution. Moreover, we analyze the interference patterns based on a recent proposal called stochastic electrodynamics with spin. Our results show that when the quantum character of the macro-system is decreased, the diffraction pattern becomes more similar (...)

    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 (...)

    It is difficult to articulate how we should take a realist attitude towards Bohmian mechanics because there are many versions of it. This paper aims to clarify the realist commitments of Bohmian mechanics and how we can understand it from a general scientific realist perspective. I use the box experiment, a double-slit like experiment conducted by Cardone et al. :1–13, 2004; Int J Mod Phys B 20:1107–1121, 2006), as a working example to argue that a causal realist (...)

    A Desperate Solution: Individual Autonomy and the Double-Blind Controlled Experiment.G. Logue & S. Wear - 1995 - Journal of Medicine and Philosophy 20 (1):57-64.
    The randomization ingredient in double-blind controlled experiments may be objectionable to patients who, in their desperation, come to such trials seeking a last chance of cure. Minogue et al., who view such a situation as inherently exploitive and undermining of patient autonomy, propose that such “desperate volunteers” instead be enrolled in the active arm, while other patients, less desperate and more committed to medical progress, continue to be randomized. Their view is critiqued as destructive of medical progress, inappropriate in its (...)

It argues that patients with diminished autonomy cannot give free and voluntary consent, and that recruitment of such patients as subjects in human experimentation exploits their vulnerability in a morally objectionable way.

    Welcher Weg? A Trajectory Representation of a Quantum Young’s Diffraction Experiment.Edward R. Floyd - 2007 - Foundations of Physics 37 (9):1403-1420.
    The double slit problem is idealized by simplifying each slit by a point source. A composite reduced action for the two correlated point sources is developed. 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.

    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 (...)

    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 (...)

    Uncertainty Principle and Uncertainty Relations.J. B. M. Uffink & Jan Hilgevoord - 1985 - Foundations of Physics 15 (9):925-944.
    It is generally believed that the uncertainty relation Δq Δp≥1/2ħ, where Δq and Δp are standard deviations, is the precise mathematical expression of the uncertainty principle for position and momentum in quantum mechanics. We show that actually it is not possible to derive from this relation two central claims of the uncertainty principle, namely, the impossibility of an arbitrarily sharp specification of both position and momentum (as in the single-slit diffraction experiment), and the impossibility of the determination of the (...)

    Objectivity Versus Nonobjectivity in Quantum Mechanics.Claudio Garola - 2000 - Foundations of Physics 30 (9):1539-1565.
    Nonobjectivity of physical properties enters physics with the standard interpretation of quantum mechanics (QM), and a number of paradoxes of this theory follow from it. It seems, however, based on sound physical arguments (double slit experiment, Heisenberg's principle, Bell–Kochen–Specker theorem, etc.), so that most physicists think that avoiding it is impossible. We discuss these arguments here and show that they can be criticized from a physical viewpoint. Our criticism proves that nonobjectivity must be considered an epistemological choice rather than (...)

    We present a quantum-mechanical analysis of Szilard's famous single-molecule engine, showing that it is analogous to the double-slit experiment. We further show that the energy derived from the engine's operation is provided by the act of observing the molecule's location. The engine can be operated with no increase in physical entropy, and the second law of thermodynamics does not compel us to relate physical entropy to informational entropy. We conclude that information per seis a subjective, idealized, concept separated (...)

    On the Measurement Problem for a Two-Level Quantum System.Alexey A. 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 (...)

    A modified Young double-slit experiment proposed by Wootters and Zurek is considered in which a system P of parallel plates covered with a photographic emulsion has been set up in the region where we would normally expect the central interference fringes. Because under certain conditions P makes it possible to conclude with much more than50% certainty through which of the two slits each particular photon passed, the relevant interference pattern becomes blurred. It is proved that this implies a (...)

    It is shown that any hidden variable model that reproduces quantum mechanics for a single particle must either be nonlocal or violate conservation of momentum. This is established by deriving an inequality which must hold in any local, momentum-conserving hidden variable model for a modified form of the double-slit experiment. It is then shown that any hidden variable model that reproduces quantum mechanics must violate the inequality. The inconsistency between the classical and quantum views of the world is (...)

The model assigns physical reality to single quantum particles. Its truth values are given open subsets of state space interpreted as the ontological conditions of a particle. Each condition determines quantum real number values for all the particle's attributes. Questions, unanswerable in the standard theories, concerning the behaviour of single particles in (...)

    Pilot-Wave Quantum Theory in Discrete Space and Time and the Principle of Least Action.Janusz Gluza & Jerzy Kosek - 2016 - Foundations of Physics 46 (11):1502-1521.
    The idea of obtaining a pilot-wave quantum theory on a lattice with discrete time is presented. The motion of quantum particles is described by a \-distributed Markov chain. Stochastic matrices of the process are found by the discrete version of the least-action principle. Probability currents are the consequence of Hamilton’s principle and the stochasticity of the Markov process is minimized. As an example, stochastic motion of single particles in a double-slit experiment is examined.

    A Note on the 'Quantum Eraser'.William Seager - 1996 - Philosophy of Science 63 (1):81-90.
    This note aims to make more familiar to philosophers yet another bizarre quantum mechanical effect with disturbing metaphysical implications. It is possible to modify the classic double-slit experiment so that one can register the path of a particle to determine which slit it passes through, and then erase this registered information so that the interference effects which would normally disappear upon registration of the "which path" information are reconstituted. Thus the "trajectory" of particles can be effected by temporally (...)

    Interfering Quantum Trajectories Without Which-Way Information.Kiran Mathew & Moncy V. John - 2017 - Foundations of Physics 47 (7):873-886.
    Quantum trajectory-based descriptions of interference between two coherent stationary waves in a double-slit experiment are presented, as given by the de Broglie–Bohm and modified de Broglie–Bohm formulations of quantum mechanics. In the dBB trajectory representation, interference between two spreading wave packets can be shown also as resulting from motion of particles. But a trajectory explanation for interference between stationary states is so far not available in this scheme. We show that both the dBB and MdBB trajectories are capable (...)

    Quantum Mechanics and Imagery: A Hermeneutical Approach. [REVIEW]Giovanni Boniolo & Francesco Gonella - 1991 - Foundations of Physics 21 (7):845-854.
    Classical and quantum descriptions are given of a double slit experiment, showing the conditions under which certain counter-intuitive conceptualizations can arise. The role played by our images of the objects and our images of the experience's results is discussed by means of a hermeneutical analysis.
