Radhakrishnan et al. (Phys. Rev. Lett. 124:110401, 2020) proposed quantum discord to multipartite systems and derived explicit formulae for any states. These results are significant in capturing correlations multiqubit systems. In this paper, we evaluate the geometric measure of obtain a large family Furthermore, investigated dynamic behavior two-, three- four-qubit states under phase noise act...

A polarization has developed in American political debates concerning the nature of society as a rational agent that implements policies to govern individual behavior. As analyzed by Lakoff, the reasons for discord are not entirely based on logical consistency, but originate in radically different moral principles based on metaphors, values, and faith. How people attend to alternative views, ha...

Deterministic quantum computation with one pure qubit (DQC1) is an efficient model of computation that uses highly mixed states. Unlike pure-state models, its power is not derived from the generation of a large amount of entanglement. Instead it has been proposed that other nonclassical correlations are responsible for the computational speedup, and that these can be captured by the quantum dis...

Rapid advances in the basic, clinical, and behavioral sciences are molding developments in conservative management of musculoskeletal disorders. Curiously, there seems to be discord developing between approaches to the assessment and management of patients, depending on whether they present with an extremity or spinal disorder. This viewpoint will comment on examples of differences emerging in ...

Fast and intelligent data mining has recently become an integral part of data analysis and a pre-requisite for modeling. This is largely due to the introduction of more sophisticated data collection tools and the possibility of observing large datasets at increased higher frequencies. This paper aims to investigate the current methodologies used for the detection of time series discord sub-sequ...

The current study examined the effect of empathy on friendship quality in the context of dyadic same-sex friendships, and how such an effect might be mediated by interpersonal competence. A special version of the actor-partner interdependence model (APIM) was used to examine this hypothesis in 146 same-sex friend dyads in 10th grade. Results showed that empathy was positively related to intimac...

Quantum Correlations are studied extensively in quantum information domain. Entanglement Measures and Quantum Discord are good examples of these actively studied correlations. Detection of violation in Bell inequalities is also a widely active area in quantum information theory world. In this work, we revisit the problem of analyzing the behavior of quantum correlations and violation of Bell in...

The sum of the Holevo quantity (that bounds the capacity of quantum channels to transmit classical information about an observable) and the quantum discord (a measure of the quantumness of correlations of that observable) yields an observable-independent total given by the quantummutual information. This split naturally delineates information about quantum systems accessible to observers – info...

Abstract Background Childhood adversity and cannabis use are considered independent risk factors for psychosis, but whether different patterns of may be acting as mediator between psychotic disorders has not yet been explored. The aim this study is to examine mediates the relationship childhood psychosis. Methods Data were utilised on 881 first-episode psychosis patients 1231 controls from Euro...

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 backgrou...
