We evaluate analytically the quantum discord for a large family of multiqubit states. It is interesting to note that three-qubits and five-qubits same, as two-qubits six-qubits. discover this states can be concluded into three categories. The level surfaces in categories shown through images. Furthermore, we investigated dynamic behavior under decoherence. For odd partite systems, prove frozen ...

We define a new measure of quantum correlations in bipartite quantum systems given by the Bures distance of the system state to the set of classical states with respect to one subsystem, that is, to the states with zero quantum discord. Our measure is a geometrical version of the quantum discord. As the latter it quantifies the degree of non-classicality in the system. For pure states it is ide...

We consider two celebrated criteria for defining the nonclassicality of bipartite bosonic quantum systems, the first stemming from information theoretic concepts and the second from physical constraints on the quantum phase space. Consequently, two sets of allegedly classical states are singled out: (i) the set C composed of the so-called classical-classical (CC) states-separable states that ar...

A growing literature reveals that parental divorce and marital discord can have undesirable effects on themental health and social well-being of children, some of which extendwell into adulthood. Our study augments this body of work by focusing on the interplay of divorce and discord in shaping the religious and spiritual lives of young adults. Several discrete subgroups of young adults are ide...

Many species have Holarctic distributions that extend across Europe, Asia and North America. Most genetics research on these species has examined only mitochondrial (mt) DNA, which has revealed wide variance in divergence between Old World (OW) and New World (NW) populations, ranging from shallow, unstructured genealogies to deeply divergent lineages. In this study, we sequenced 20 nuclear intr...

Any two-qubit state can be represented, geometrically, as an ellipsoid with a certain size and center located within the Bloch sphere of one of the qubits. Points of this ellipsoid represent the postmeasurement states when the other qubit is measured. Based on the most demolition concept in the definition of quantum discord, we study the amount of demolition when the two post-measurement states...
