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…
Direct measurement of finite-time disentanglement induced by a reservoir
M. Franca Santos, P. Milman, L. Davidovich +1
We propose a method for directly probing the dynamics of disentanglement of an initial two-qubit entangled state, under the action of a reservoir. We show that it is possible to de…
Squeezing generation and revivals in a cavity-ion system in contact with a reservoir
R. Rangel, L. Carvalho, N. Zagury
We consider a system consisting of a single two-level ion in a harmonic trap, which is localized inside a non-ideal optical cavity at zero temperature and subjected to the action o…
Field squeeze operators in optical cavities with atomic ensembles
R. Guzmán, J. C. Retamal, E. Solano +1
We propose a method of generating unitarily single and two-mode field squeezing in an optical cavity with an atomic cloud. Through a suitable laser system, we are able to engineer…
