Quantum Ratchets for Quantum Communication with Optical Superlattices
Oriol Romero-Isart, Juan Jose Garcia-Ripoll
We propose to use a quantum ratchet to transport quantum information in a chain of atoms trapped in an optical superlattice. The quantum ratchet is created by a continuous modulati…
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…
