Threshold effect for probabilistic entanglement swapping
Luis Roa Oppliger, Torben L. Purz, Ariana Muñoz +3
The basic \emph{entanglement swapping protocol} allows to project two qubits, which have never interacted, onto a maximally entangled state. For deterministic swapping, the key ing…
Tomography from collective measurements
A. Muñoz, A. B. Klimov, M. Grassl +1
We discuss the tomography of -qubit states using collective measurements. The method is exact for symmetric states, whereas for not completely symmetric states the information a…
Entanglement thresholds for displaying the quantum nature of teleportation
Luis Roa, Robinson Gómez, Ariana Muñoz +1
A protocol for transferring an unknown single qubit state has quantum features when the average fidelity of the outcomes is greater than 2/3. We use the probabilistic and unambiguo…
Entanglement-swapping for X-states demands threshold values
Ariana Muñoz, Gesa Grüning, Luis Roa
The basic entanglement-swapping scheme can be seen as a process which allows to redistribute the Bell states' properties between different pairs of a four qubits system. Achieving…
