Accenting Accessible Information
In a perception experiment in German, subjects judged the appropriateness of three types of nuclear pitch accent (including deaccentuation) on non-pronominal anaphoric referring expressions, which were either textually or inferentially accessible from the preceding context. Results confirm that accessible information can indeed be accented – and in some cases must be. However, not all accents a...
متن کاملAccessible information in quantum measurement
The amount of information that can be accessed via measurement of a quantum system prepared in different states is limited by the Holevo bound. We present a simple proof of this theorem and its extension to sequential measurements based on the properties of quantum conditional and mutual entropies. The proof relies on a minimal physical model of the measurement which does not assume environment...
متن کاملNon-Markovianity through accessible information
Quantum discord (QD) measures the fraction of the pairwise mutual information that is locally inaccessible in a multipartite system. Fundamental aspects related to two important measures in quantum information theory, namely the entanglement of formation (EOF) and the conditional entropy, can be understood in terms of the distribution of this form of local inaccessible information (LII). As suc...
متن کاملAccessible information and quantum operations
It is impossible to perfectly clone an unknown quantum state using unitary evolution [1]. That non-orthogonal states can’t be distinguished is well known [2]. In [3], Mor and Terno showed that an arbitrary state cannot be disentangled, a universal disentangling machine cannot exist. It is well known that the laws of quantum mechanics allow us to do many things superior comparing with classical ...
متن کاملLocally Accessible Information and Distillation of Entanglement
The problem of local distinguishability of orthogonal quantum states has raised much interest in the arena of quantum information. Interestingly where any two pure orthogonal states can be distinguished locally [1], there exists more than two orthogonal states which can not be distinguished by local operations and classical communication (LOCC) [2, 3]. All these results lead to investigate the ...
