Journal ArticleDOI
Quantum Computations with Cold Trapped Ions.
J. I. Cirac,Peter Zoller +1 more
TL;DR: A quantum computer can be implemented with cold ions confined in a linear trap and interacting with laser beams, where decoherence is negligible, and the measurement can be carried out with a high efficiency.
Journal ArticleDOI
Long-distance quantum communication with atomic ensembles and linear optics
TL;DR: It is shown that the communication efficiency scales polynomially with the channel length, and hence the scheme should be operable over very long distances.
Journal ArticleDOI
Three qubits can be entangled in two inequivalent ways
TL;DR: In this paper, it was shown that the Greenberger-Horne-Zeilinger state and a W state retain maximally bipartite entanglement when any one of the three qubits is traced out.
Journal ArticleDOI
Cold Bosonic Atoms in Optical Lattices
Dieter Jaksch,Dieter Jaksch,Christoph Bruder,Christoph Bruder,J. I. Cirac,J. I. Cirac,Crispin W. Gardiner,Crispin W. Gardiner,Peter Zoller,Peter Zoller +9 more
TL;DR: In this paper, the Bose-Hubbard model was used to model the phase transition from the superfluid to the Mott insulator phase induced by varying the depth of the optical potential.
Journal ArticleDOI
Quantum Repeaters: The Role of Imperfect Local Operations in Quantum Communication
TL;DR: This work presents a scheme of a quantum repeater that connects a string of (imperfect) entangled pairs of particles by using a novel nested purification protocol, thereby creating a single distant pair of high fidelity.
