A Consistent Quantum Ontology
The (consistent or decoherent) histories interpretation provides a consistent realistic ontology for quantum mechanics, based on two main ideas. First, a logic (system of reasoning) is employed which is compatible with the Hilbert-space structure of quantum mechanics as understood by von Neumann: quantum properties and their negations correspond to subspaces and their orthogonal complements. It...
متن کاملConsistent Loop Quantum Cosmology
A consistent combination of quantum geometry effects rules out a large class of models of loop quantum cosmology and their critical densities as they have been used in the recent literature. In particular, the critical density at which an isotropic universe filled with a free, massless scalar field would bounce must be well below the Planck density. In the presence of anisotropy, no model of th...
متن کاملConsistent Quantum Counterfactuals
An analysis using classical stochastic processes is used to construct a consistent system of quantum counterfactual reasoning. When applied to a counterfactual version of Hardy’s paradox, it shows that the probabilistic character of quantum reasoning together with the “one framework” rule prevents a logical contradiction, and there is no evidence within this approach for any nonlocal influences...
متن کاملConsistent Quantum Reasoning
Precise rules are developed in order to formalize the reasoning processes involved in standard non-relativistic quantum mechanics, with the help of analogies from classical physics. A classical or quantum description of a mechanical system involves a framework, often chosen implicitly, and a statement or assertion about the system which is either true or false within the framework with which it...
متن کاملA Causal Agent Quantum Ontology
Quantum theory is widely regarded as the most successful scientific theory to date. As a foundational physical theory, its range extends from the sub-microscopic to the interstellar, excluding only phenomena for which gravitational spacetime curvature cannot be neglected. Even its most surprising empirical predictions have been borne out to extraordinarily high accuracy. Yet the ontological sta...
