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…
Increasing identical particle entanglement by fuzzy measurements
D. Cavalcanti, M. F. Santos, M. O. Terra Cunha +2
We investigate the effects of fuzzy measurements on spin entanglement for identical particles, both fermions and bosons. We first consider an ideal measurement apparatus and define…
Decoherence and localization in the double well model
Gabriela Barreto Lemos, M. F. Santos, J. G. Peixoto de Faria +2
We use a spin-1/2 model to analyze tunnelling in a double well system coupled to an external reservoir. We consider different noise sources such as fluctuations on the height and c…
Entanglement between two macroscopic fields by coherent atom-mediated exchange of photons
C. L. Garrido Alzar, M. Franca Santos, P. Nussenzveig
Using two different criteria for continuous variable systems we demonstrated that pump and probe beams became quantum correlated in a situation of Electromagnetically Induced Trans…
