Quantum switches and quantum memories for matter-wave lattice solitons
V. Ahufinger, A. Mebrahtu, R. Corbalan +1
We study the possibility of implementing a quantum switch and a quantum memory for matter wave lattice solitons by making them interact with "effective" potentials (barrier/well) c…
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…
Predicting spinor condensate dynamics from simple principles
M. Moreno-Cardoner, J. Mur-Petit, M. Guilleumas +3
We study the spin dynamics of quasi-one-dimensional F=1 condensates both at zero and finite temperatures for arbitrary initial spin configurations. The rich dynamical evolution exh…
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…
Quantum polarization spectroscopy of ultracold spinor gases
K. Eckert, L. Zawitkowski, A. Sanpera +2
We propose a method for the detection of ground state quantum phases of spinor gases through a series of two quantum nondemolition measurements performed by sending off-resonant, p…
Trapped Ion Chain as a Neural Network: Error Resistant Quantum Computation
Marisa Pons, Veronica Ahufinger, Christof Wunderlich +5
We demonstrate the possibility of realizing a neural network in a chain of trapped ions with induced long range interactions. Such models permit one to store information distribute…
