Entanglement in bipartite quantum systems: Euclidean volume ratios and detectability by Bell inequalities
A. Sauer, J. Z. Bernád, H. J. Moreno +1
Euclidean volume ratios between quantum states with positive partial transpose and all quantum states in bipartite systems are investigated. These ratios allow a quantitative explo…
Generation of entangled matter qubits in two opposing parabolic mirrors
N. Trautmann, J. Z. Bernád, M. Sondermann +3
We propose a scheme for the remote preparation of entangled matter qubits in free space. For this purpose, a setup of two opposing parabolic mirrors is considered, each one with a…
Quantum teleportation and entanglement swapping of matter qubits with coherent multiphoton states
J. M. Torres, J. Z. Bernád, G. Alber
Protocols for probabilistic entanglement-assisted quantum teleportation and for entanglement swapping of material qubits are presented. They are based on a protocol for postselecti…
Manipulating sudden death of entanglement of two-qubit X-states in thermal reservoirs
Mazhar Ali, G. Alber, A. R. P. Rau
Manipulation of sudden death of entanglement (ESD) of two qubits interacting with statistically uncorrelated thermal reservoirs is investigated. It is shown that for initially prep…
Locality, detection efficiencies, and probability polytopes
J. Wilms, Y. Disser, G. Alber +1
We present a detailed investigation of minimum detection efficiencies, below which locality cannot be violated by any quantum system of any dimension in bipartite Bell experiments.…
Hastening, delaying, or averting sudden death of quantum entanglement
A. R. P. Rau, Mazhar Ali, G. Alber
The finite time end of entanglement between two decohering qubits can be modified by local, unitary actions performed during the decohering process. Depending on the time when such…
