  1. Quantum Deep Learning Triuniverse.Angus McCoss - 2016 - Journal of Quantum Information Science 6 (4).
    An original quantum foundations concept of a deep learning computational Universe is introduced. The fundamental information of the Universe (or Triuniverse)is postulated to evolve about itself in a Red, Green and Blue (RGB) tricoloured stable self-mutuality in three information processing loops. The colour is a non-optical information label. The information processing loops form a feedback-reinforced deep learning macrocycle with trefoil knot topology. Fundamental information processing is driven by ψ-Epistemic Drive, the Natural appetite for information selected for advantageous knowledge. From its (...)

  • Is an Electron a Charge Cloud? A Reexamination of Schrödinger’s Charge Density Hypothesis.Shan Gao - 2018 - Foundations of Science 23 (1):145-157.
    This article re-examines Schrödinger’s charge density hypothesis, according to which the charge of an electron is distributed in the whole space, and the charge density in each position is proportional to the modulus squared of the wave function of the electron there. It is shown that the charge distribution of a quantum system can be measured by protective measurements as expectation values of certain observables, and the results as predicted by quantum mechanics confirm Schrödinger’s original hypothesis. Moreover, the physical origin (...)

  • (1 other version)Why protective measurement implies the reality of the wave function: further consolidation.Shan Gao - 2019 - In Diederik Aerts, Dalla Chiara, Maria Luisa, Christian de Ronde & Decio Krause (eds.), Probing the meaning of quantum mechanics: information, contextuality, relationalism and entanglement: Proceedings of the II International Workshop on Quantum Mechanics and Quantum Information: Physical, Philosophical and Logical Approaches, CLEA, Brussels. New Jersey: World Scientific.
    The existing psi-ontology theorems are based on a simplified assumption of the ontological models framework, according to which when a measurement is performed the behaviour of the measuring device is determined by the ontic state of the measured system immediately before the measurement. In this paper, I give an argument for the reality of the wave function in terms of protective measurements under a more reasonable assumption, according to which the behaviour of the measuring device during a measurement is determined (...)

  • (1 other version)Protective Measurements and the Reality of the Wave Function.Shan Gao - 2022 - British Journal for the Philosophy of Science 73 (3):777-794.
    It has been debated whether protective measurement implies the reality of the wave function. In this article, I present a new analysis of the relationship between protective measurements and the reality of the wave function. First, I briefly introduce protective measurements and the ontological models framework for them. Second, I give a simple proof of Hardy’s theorem in terms of protective measurements. Third, I analyse two suggested ψ -epistemic models of a protective measurement. It is shown that although these models (...)

  • Why protective measurement establishes the reality of the wave function.Shan Gao - unknown
    It has been debated whether protective measurement implies the reality of the wave function. In this paper, I present a new analysis of the relationship between protective measurement and the reality of the wave function. First, I briefly introduce protective measurements and the ontological models framework for them. Second, I give a simple proof of Hardy's theorem in terms of protective measurements. It shows that when assuming the ontic state of the protected system keeps unchanged during a protective measurement, the (...)

  • (1 other version)The measurement problem revisited.Shan Gao - unknown
    It has been realized that in order to solve the measurement problem, the physical state representing the measurement result is required to be also the physical state on which the mental state of an observer supervenes. This introduces an additional restriction on the solutions to the measurement problem. In this paper, I give a new formulation of the measurement problem which lays more stress on psychophysical connection, and analyze whether Everett's theory, Bohm's theory and dynamical collapse theories can satisfy the (...)

  • Does protective measurement imply the reality of the wave function?Shan Gao - unknown
    Recently the first protective measurement has been realized in experiment [Nature Phys. 13, 1191 ], which can measure the expectation value of an observable from a single quantum system. This raises an important and pressing issue of whether protective measurement implies the reality of the wave function. If the answer is yes, this will improve the influential PBR theorem [Nature Phys. 8, 475 ] by removing auxiliary assumptions, and help settle the issue about the nature of the wave function. In (...)
