The relation between the quantum discord and quantum teleportation: The physical interpretation of the transition point between different quantum discord decay regimes

2015 · Europhysics Letters (EPL)

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-correlated state of the two qubits is used …
