Analytical expression of quantum discord for rank-2 two-qubit states

Quantum Information Processing, 2018
Quantum correlations characterized by quantum entanglement and quantum discord play important roles in many quantum information processing. We study the relations among the entanglement of formation, concurrence, tangle, linear entropy-based classical ...

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 ...
