Metric adjusted skew information.
We extend the concept of Wigner-Yanase-Dyson skew information to something we call "metric adjusted skew information" (of a state with respect to a conserved observable). This "skew information" is intended to be a non-negative quantity bounded by the variance (of an observable in a state) that vanishes for observables commuting with the state. We show that the skew information is a convex func...
متن کاملUncertainty Relations for Generalized Metric Adjusted Skew Information and Generalized Metric Adjusted Correlation Measure
Correspondence: [email protected] Graduate School of Science and Engineering, Yamaguchi University, 755-8611 Une, Japan Full list of author information is available at the end of the article Abstract In this paper, we give a Heisenberg type or a Schrödinger-type uncertainty relation for generalized metric adjusted skew information or generalized metric adjusted correlation measure. These...
متن کاملMetric adjusted skew information, Metric adjusted correlation measure and Uncertainty relations
Inspired by the recent results in [4] and the concept of metric adjusted skew information introduced by Hansen in [6], we here give a further generalization for Schrödinger-type uncertainty relation applying metric adjusted correlation measure introduced in [6]. We firstly give some notations according to those in [4]. Let Mn(C) and Mn,sa(C) be the set of all n × n complex matrices and all n × ...
متن کاملSchrödinger uncertainty relation, Wigner-Yanase-Dyson skew information and metric adjusted correlation measure
In this paper, we give Schrödinger-type uncertainty relation using the WignerYanase-Dyson skew information. In addition, we give Schrödinger-type uncertainty relation by use of a two-parameter extended correlation measure. We finally show the further generalization of Schrödinger-type uncertainty relation by use of the metric adjusted correlation measure. These results generalize our previous r...
متن کاملInformation and Its Metric
Information is taken as the primary physical entity from which probabilities can be derived. Information produced by a source is defined as the class of sources that are recodingequivalent. Shannon entropy is one of a family of formal Renyi information measures on the space of unique sources. Each of these measures quantifies the volume of the source’s recoding-equivalence class. A space of inf...
