Efficiency in Quantum Key Distribution Protocols with Entangled Gaussian States
C. Rodó, O. Romero-Isart, K. Eckert +1
Quantum key distribution (QKD) refers to specific quantum strategies which permit the secure distribution of a secret key between two parties that wish to communicate secretly. Qua…
Quantum State Transfer in Spin-1 Chains
O. Romero-Isart, K. Eckert, A. Sanpera
We study the transfer of quantum information through a Heisenberg spin-1 chain prepared in its ground state. We measure the efficiency of such a quantum channel {\em via} the fidel…
A deterministic cavity-QED source of polarization entangled photon pairs
R. Garcia-Maraver, K. Eckert, R. Corbalan +1
We present two cavity quantum electrodynamics proposals that, sharing the same basic elements, allow for the deterministic generation of entangled photons pairs by means of a three…
