  1. Protective Measurement and the Meaning of the Wave Function.Shan Gao - 2011
    This article analyzes the implications of protective measurement for the meaning of the wave function. According to protective measurement, a charged quantum system has mass and charge density proportional to the modulus square of its wave function. It is shown that the mass and charge density is not real but effective, formed by the ergodic motion of a localized particle with the total mass and charge of the system. Moreover, it is argued that the ergodic motion is not continuous but (...)

  • Protective Measurements and Relativity of Worlds.Shan Gao - unknown
    It is a fundamental and widely accepted assumption that a measurement result exists universally, and in particular, it exists for every observer, independently of whether the observer makes the measurement or knows the result. In this paper, we will argue that, based on an analysis of protective measurements, this assumption is rejected by the many-worlds interpretation of quantum mechanics, and worlds, if they indeed exist according to the interpretation, can only exist relative to systems which are decoherent with respect to (...)

  • An Exceptionally Simple Argument Against the Many-Worlds Interpretation: Further Consolidations.Shan Gao - unknown
    It is argued that the components of the superposed wave function of a measuring device, each of which represents a definite measurement result, do not correspond to many worlds, one of which is our world, because all components of the wave function can be measured in our world by a serious of protective measurements, and they all exist in this world.

  • Distinct Quantum States Cannot Be Compatible with a Single State of Reality.Shan Gao - unknown
    Recently Lewis et al. [Phys. Rev. Lett. 109, 150404 ] demonstrated that additional assumptions such as preparation independence are always necessary to rule out a psi-epistemic model, in which the quantum state is not uniquely determined by the underlying physical state. Their conclusion is based on an analysis of conventional projective measurements. Here we demonstrate that protective measurements, which are distinct from projective measurements, already shows that distinct quantum states cannot be compatible with a single state of reality. This improves (...)

  • Protective Measurements and the Meaning of the Wave Function in the de Broglie-Bohm Theory.Shan Gao - unknown
    There are three possible interpretations of the wave function in the de Broglie-Bohm theory: taking the wave function as corresponding to a physical entity or a property of the Bohmian particles or a law. In this paper, we argue that the first interpretation is favored by an analysis of protective measurements.

  • 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 (...)
