Two measures of quantum correlations and some applications
نویسندگان
چکیده
This paper reviews two well-studied measures of quantum correlations which exist between the subsystems that consists the most simple composite systems (bipartite systems). The first one is Entanglement of Formation (EoF) and quantifies the entanglement while the second one, the quantum discord (QD), is a measure of all quantum correlations of the bipartite system. Here the theoretical background is presented in order to give the definitions of these two measures and afterwards three cases are analyzed where we can implement these measures of quantum correlations. The three applications that we discuss here, are described by completely different equations and as a result we notice the usefulness and the universality of entanglement of formation and quantum discord.

متن کاملSOME SIMILARITY MEASURES FOR PICTURE FUZZY SETS AND THEIR APPLICATIONS
In this work, we shall present some novel process to measure the similarity between picture fuzzy sets. Firstly, we adopt the concept of intuitionistic fuzzy sets, interval-valued intuitionistic fuzzy sets and picture fuzzy sets. Secondly, we develop some similarity measures between picture fuzzy sets, such as, cosine similarity measure, weighted cosine similarity measure, set-theoretic similar...
متن کاملOne-point Goppa Codes on Some Genus 3 Curves with Applications in Quantum Error-Correcting Codes
We investigate one-point algebraic geometric codes CL(D, G) associated to maximal curves recently characterized by Tafazolian and Torres given by the affine equation yl = f(x), where f(x) is a separable polynomial of degree r relatively prime to l. We mainly focus on the curve y4 = x3 +x and Picard curves given by the equations y3 = x4-x and y3 = x4 -1. As a result, we obtain exact value of min...
متن کاملTranslation Invariant Approach for Measuring Similarity of Signals
In many signal processing applications, an appropriate measure to compare two signals plays a fundamental role in both implementing the algorithm and evaluating its performance. Several techniques have been introduced in literature as similarity measures. However, the existing measures are often either impractical for some applications or they have unsatisfactory results in some other applicati...
