Temperature-dependent remote control of polarization and coherence intensity with pure sender's initial state
E. B. Fel'dman, E. I. Kuznetsova, A. I. Zenchuk
We study the remote creation of the polarization and intensity of the first-order coherence (or coherence intensity) in long spin-1/2 chains with one qubit sender and receiver. The…

Contributions of different parts of spin-spin interactions to quantum correlations in a spin ring model in an external magnetic field
S. I. Doronin, E. B. Fel'dman, E. I. Kuznetsova
We study quantum correlations in a bipartite heteronuclear system in an external magnetic field. The system consists of a spin ring with an arbitrary number of…
