Quantum correlations

Quantum correlations (entanglement or that qualified by quantum discord) is basis of quantum information science as they can serve as a resource for various communication protocols: coding, cryptography, teleportaion etc. Our primary aim is to consider behaviour of various types of quantum correlations affected by thermal and non-thermal environments.
