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…

Analytical solutions and criteria for the quantum discord of two-qubit X-states
A. Maldonado-Trapp, Anzi Hu, Luis Roa
Except for a few special states, computing quantum discord remains a complicated optimization process. In this paper we present analytical solutions for computing quantum discord o…
