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…

Optical signatures of spin dependent coupling in semimagnetic quantum dot molecules
Ł. Kłopotowski, P. Wojnar, Ł. Cywiński +5
We present photoluminescence studies of CdTe and CdMnTe quantum dots grown in two adjacent layers. We show that when the dots are 8 nm apart, their magnetooptical properties - Zeem…
