Entanglement of atoms via cold controlled collisions
D. Jaksch, H. -J. Briegel, J. I. Cirac +2
We show that by using cold controlled collisions between two atoms one can achieve conditional dynamics in moving trap potentials. We discuss implementing two qubit quantum--gates…
Lower Bounds for Attainable Fidelity in Entanglement Purification
G. Giedke, H. Briegel, J. I. Cirac +1
We derive lower bounds for the attainable fidelity of standard entanglement purification protocols when local operations and measurements are subjected to errors. We introduce an e…
Quantum repeaters based on entanglement purification
W. Dür, H. - J. Briegel, J. I. Cirac +1
We study the use of entanglement purification for quantum communication over long distances. For distances much longer than the coherence length of a corresponding noisy quantum ch…
Quantum repeaters for communication
H. -J. Briegel, W. Dür, J. I. Cirac +1
In quantum communication via noisy channels, the error probability scales exponentially with the length of the channel. We present a scheme of a quantum repeater that overcomes thi…
