Measurements and Consistent Families of Quantum Channels
Abstract. This article introduces the notion of consistent families (⇤)n 1 of Quantum Channels. These families correspond to simultaneous observation of di↵erent copies of a given quantum system. Here, we are primarily interested in the analysis of measurements connected with them. As usual, the measurement of a quantum system requires the construction of a classical dilation of the correspondi...
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 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...
