Dynamics of quantum discord and geometric quantum discord in multiqubit interacting system

Chinese Physics B
Abstract Using quantum discord (QD) and geometric quantum discord (GQD), quantum correlation dynamics is investigated for two coupled qubits within a multiqubit interacting system in the zero-temperature bosonic reservoir, under both weak and strong qubit-reservoir coupling regimes. The multiqubit system is connected with either a common

Quantum Discord in Quantum Communication Protocols

2017
We review an operational interpretation of quantum discord by quantifying it as the difference in the yield of the noisy and noiseless fully quantum Slepian-Wolf (FQSW) protocol and the closely related Mother protocol. The fully quantum Slepian-Wolf protocol is the most general form of unidirectional and bipartite quantum communication protocols and ...

Quantum Discord in Quantum Information Theory

2014
The role of quantum discord in the task of remote state preparation was considered by Dakic et al. (Nature Physics 8:666–670, 2012). In this task Alice aims to remotely prepare Bob’s system in the quantum state \(\mathinner {|{\psi }\rangle }=\frac{1}{\sqrt{2}}(\mathinner {|{0}\rangle }+e^{i\phi }\mathinner {|{1}\rangle }).\) To this end Alice and Bob ...
