We explore and develop the mathematics of the theory of entanglement measures. After a careful review and analysis of definitions, of preliminary results, and of connections between conditions on entanglement measures, we prove a sharpened version of

It is proposed that the physical structure of an observer in quantum mechanics is constituted by a pattern of elementary localized switching events. A key preliminary step in giving mathematical expression to this proposal is the introduction of an e

A physical and mathematical framework for the analysis of probabilities in quantum theory is proposed and developed. One purpose is to surmount the problem, crucial to any reconciliation between quantum theory and space-time physics, of requiring ins

A human brain operates as a pattern of switching. An abstract definition of a quantum mechanical switch is given that allows for the continual random fluctuations in the warm wet environment of the brain. Among several switch-like entities in the bra

We obtain a mathematically simple characterization of all functionals coinciding with the von Neumann reduced entropy on pure states based on the Khinchin-Faddeev axiomatization of Shannon entropy and give a physical interpretation of the axioms in t

We show that an entanglement measure called relative entropy of entanglement satisfies a strong continuity condition. If two states are close to each other then so are their entanglements per particle pair in this measure. It follows in particular, t

Some technical results about discontinuity and continuity of eigenprojections of reduced density operators are discussed in an elementary context. It is argued that these results suggest serious obstacles both to the goal of applying the modal interp

The original development of the formalism of quantum mechanics involved the study of isolated quantum systems in pure states. Such systems fail to capture important aspects of the warm, wet, and noisy physical world which can better be modelled by qu

Let (ωn)n≧1 be a norm convergent sequence of normal states on a von Neumann algebraA withωn→ω. Let (kn)n≧1 be a strongly convergent sequence of self-adjoint elements ofA withkn→k. It is shown that the sequence\((\omega _n^{k_n } )_{n \geqq
