Characterization and measurement of qubit-environment entanglement generation during pure dephasing
Katarzyna Roszak, Łukasz Cywiński
We consider the coupling of a qubit in a pure state to an environment in an arbitrary state, and characterize the possibility of qubit-environment entanglement generation during th…

The relation between the quantum discord and quantum teleportation: the physical interpretation of the transition point between different quantum discord decay regimes
Katarzyna Roszak, Łukasz Cywiński
We study quantum teleportation via Bell-diagonal mixed states of two qubits in the context of the intrinsic properties of the quantum discord. We show that when the quantum-correla…
