Finite size effects in entangled rings of qubits
T. Meyer, U. V. Poulsen, K. Eckert +2
We study translationally invariant rings of qubits with a finite number of sites N, and find the maximal nearest-neighbor entanglement for a fixed z component of the total spin. Fo…

Squeezed Condensates
Uffe V. Poulsen, Klaus Molmer
We analyse the atomic state obtained by photo-dissociation of a molecular Bose-Einstein-condensate. This process is equivalent to down-conversion in quantum optics where it is resp…
