|Title:||Unification of quantum and classical correlations and quantumness measures||Authors:||Modi, K.
|Issue Date:||2011||Citation:||Modi, K., Vedral, V. (2011). Unification of quantum and classical correlations and quantumness measures. AIP Conference Proceedings 1384 : 69-75. ScholarBank@NUS Repository. https://doi.org/10.1063/1.3635845||Abstract:||We give a pedagogical introduction to quantum discord and discuss the problem of separation of total correlations in a given quantum state into entanglement, dissonance, and classical correlations using the concept of relative entropy. This allows us to put all correlations on an equal footing. Entanglement and dissonance jointly belong to what is known as quantum discord. Our methods are completely applicable for multipartite systems of arbitrary dimensions. We finally show, using relative entropy, how different notions of quantum correlations are related to each other. This gives a single theory that incorporates all correlations, quantum and classical, and different methods of quantifying them. © 2011 American Institute of Physics.||Source Title:||AIP Conference Proceedings||URI:||http://scholarbank.nus.edu.sg/handle/10635/116800||ISBN:||9780735409453||ISSN:||0094243X||DOI:||10.1063/1.3635845|
