摘要

The effect of a carefully chosen measurement action is proposed to be able to influence the probability distribution of future outcomes. Using the consistent histories formalism, we may calculate the overlap between a current measurement action and an array of possible future states. We propose an interpretation of the mathematics in which a current measurement action reaches recursively into future states and returns a probability. Using intermediate decomposition of a quantum history, we decompose a state at intermediate times into a complete set of states, using a grouping which distinguishes particular outcomes. The "meaning" of the grouping is defined rigorously, and it is shown that under certain minimal assumptions a 'meaningful grouping' will always increase the likelihood of a particular outcome. This is labeled "meaningful history selection." Grouping histories is not a physical process, but rather an information theoretic one that occurs during the measurement process. The model is consistent with the standard Von Neumann measurement process under normal conditions, but leads to a proposed small deviation in the presence of a conscious observer that naturally accommodates the experimental evidence of certain psi phenomena. It is proposed that the effect of a conscious observer acting on a system is to group the histories in a distinguishable way, thereby minimizing the entropy increase of the system upon measurement. Compatibility with various models of quantum theory are discussed.
