Quantum polarization spectroscopy of correlations in attractive fermionic gases
T. Roscilde, M. Rodriguez, K. Eckert +4
We show how spin-spin correlations, detected in a non-destructive way via spatially resolved quantum polarization spectroscopy, strongly characterize various phases realized in tra…
Generation of entangled photon pairs in optical cavity-QED: Operating in the bad cavity limit
R. García-Maraver, K. Eckert, R. Corbalán +1
We propose an optical cavity-QED scheme for the deterministic generation of polarization entangled photon pairs that operates with high fidelity even in the bad cavity limit. The s…
Quantum Non-Demolition Detection of Strongly Correlated Systems
Kai Eckert, Oriol Romero-Isart, Mirta Rodriguez +3
Preparation, manipulation, and detection of strongly correlated states of quantum many body systems are among the most important goals and challenges of modern physics. Ultracold a…
Transport and Entanglement Generation in the Bose-Hubbard Model
O. Romero-Isart, K. Eckert, C. Rodó +1
We study entanglement generation via particle transport across a one-dimensional system described by the Bose-Hubbard Hamiltonian. We analyze how the competition between interactio…
Efficient quantum state transfer in spin chains via adiabatic passage
K. Eckert, O. Romero-Isart, A. Sanpera
We propose a method for quantum state transfer in spin chains using an adiabatic passage technique. Modifying even and odd nearest-neighbour couplings in time allows to achieve tra…
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…
