Sudden Birth Versus Sudden Death of Entanglement in Multipartite Systems
C. E. Lopez, G. Romero, F. Lastra +2
We study the entanglement dynamics of two cavities interacting with independent reservoirs. Expectedly, we observe that, as the cavity entanglement is depleted, it is transferred t…

Entangled coherent states under dissipation
F. Lastra, G. Romero, C. E. Lopez +2
We study the evolution of entangled coherent states of the two quantized electromagnetic fields under dissipation. Characteristic time scales for the decay of the negativity are fo…

Direct measurement of concurrence for atomic two-qubit pure states
G. Romero, C. E. Lopez, F. Lastra +2
We propose a general scheme to measure the concurrence of an arbitrary two-qubit pure state in atomic systems. The protocol is based on one- and two-qubit operations acting on two…
