Multipartite continuous-variable quantum nondemolition interaction and entanglement certification and monitoring
Vinícius V. Seco, Alencar J. de Faria
The quantum nondemolition (QND) measurement is one of the most studied quantum measurement procedures. Usually, such process involves the coupling of a single system of interest, c…
Robust Gaussian Teleportation with Attenuations and Non-unity Gain
Alencar J. de Faria
The average fidelity of the teleportation of a coherent state is calculated for general Gaussian bipartite systems shared by the partners of the protocol, Alice and Bob. It is cons…
Nondestructive verification of continuous-variable entanglement
Alencar J. de Faria
An optical procedure in the context of continuous variables to verify bipartite entanglement without destroying both systems and their entanglement is proposed. To perform the nond…
Robustness of bipartite Gaussian entangled beams propagating in lossy channels
F. A. S. Barbosa, A. S. Coelho, A. J. de Faria +4
Subtle quantum properties offer exciting new prospects in optical communications. Quantum entanglement enables the secure exchange of cryptographic keys and the distribution of qua…
Disentanglement in Bipartite Continuous-Variable Systems
F. A. S. Barbosa, A. S. Coelho, A. J. de Faria +4
Entanglement in bipartite continuous-variable systems is investigated in the presence of partial losses, such as those introduced by a realistic quantum communication channel, e.g.…
