• Title: The Explanation of Entanglement in Quantum Mechanics
• Authors: H S Perlman
• Abstract summary: Pure states, i.e., probability distributions of measurement values, cannot inhere in elementary particles and therefore cannot be regarded as interacting causally. The areas in quantum mechanics in which causal interactions are relevant include, though not explicitly, measurement and therefore the Born rule, and, explicitly, the unitary Schrodinger time development of states.

• Abstract: It is shown that quantum mechanics is, like thermodynamics, a phenomenological theory i.e., not a causal theory, ( not because it is a statistical theory - statistical theories with caused probability distributions can be regarded as causal) but because pure states, i.e., probability distributions of measurement values, cannot inhere in elementary particles and therefore cannot change when their world tubes intersect and hence they cannot be regarded as interacting causally. By a causal theory is meant a theory that specifies the changes in time of the states of causally interacting entities in its domain. The areas in quantum mechanics in which causal interactions are relevant include, though not explicitly, measurement and therefore the Born rule, and, explicitly, the unitary Schrodinger time development of states. The Born rule probabilities are shown to to refer not to conjoint superpositions of eigenstates but to classical mixtures of mutually exclusive eigenvalues and the Schrodinger time development of states is shown to refer to the time development of the states of non-causally interacting elementary particles and hence cannot be regarded as as a causal time development equation, appearances to the contrary notwithstanding. The recognition that quantum mechanics is not a causal theory but a phenomenological theory like thermodynamics does not affect the way it is employed to calculate an predict and hence preserves its empirical success but it does allow a typically simple phenomenological theory explanation of entanglement and other apparently non-local phenomena.

  We argue that the composition postulate deserves to be experimentally scrutinised independently of the other features of quantum theory. We formulate a family of operational theories that are solely distinguished from quantum theory by their system-composition rule.

  We show that nomic toy theory has incompatible measurements and the complete state of a physical system cannot be known. We reconcile this with measurement uncertainty as an aspect of the inseparability of subjects and objects. This work invites further investigations, such as the one of (full) quantum theory.

  Quantum interference phenomena are widely viewed as posing a challenge to the classical worldview. We show that such conclusions are not, in fact, forced on us by basic interference phenomena. We do so by describing an alternative to quantum theory, a statistical theory of a classical discrete field.
