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…
Selective Control of the Symmetric Dicke Subspace in Trapped Ions
C. E. Lopez, J. C. Retamal, E. Solano
We propose a method of manipulating selectively the symmetric Dicke subspace in the internal degrees of freedom of N trapped ions. We show that the direct access to ionic-motional…
Abrupt Changes in the Dynamics of Quantum Disentanglement
F. Lastra, G. Romero, C. E. López +2
Entanglement evolution in high dimensional bipartite systems under dissipation is studied. Discontinuities for the time derivative of the lower bound of entanglement of formation i…
Quantum information transfer for qutrits
A. Delgado, C. Saavedra, J. C. Retamal
We propose a scheme for the transfer of quantum information among distant qutrits. We apply this scheme to the distribution of entanglement among distant nodes and to the generatio…
Entanglement properties in the Inhomogeneous Tavis-Cummings model
C. E. López, F. Lastra, G. Romero +1
In this work we study the properties of the atomic entanglement in the eigenstates spectrum of the inhomogeneous Tavis-Cummings Model. The inhomogeneity is present in the coupling…
Single observable concurrence measurement without simultaneous copies
A. Salles, F. de Melo, J. C. Retamal +2
We present a protocol that allows us to obtain the concurrence of any two qubit pure state by performing a minimal and optimal tomography of one of the subsystems through measuring…
