Error correction in ensemble registers for quantum repeaters and quantum computers

Etienne Brion, Line Hjortshoj Pedersen, Mark Saffman +1

We propose to use a collective excitation blockade mechanism to identify errors that occur due to disturbances of single atoms in ensemble quantum registers where qubits are stored…

Laser cooling in the Penning trap: an analytical model for cooling rates in the presence of an axializing field

R. J. Hendricks, E. S. Phillips, D. M. Segal +1

Ions stored in Penning traps may have useful applications in the field of quantum information processing. There are, however, difficulties associated with the laser cooling of one…

Transforming squeezed light into a large amplitude coherent state superposition

Anne E. B. Nielsen, Klaus Mølmer

A quantum superposition of two coherent states of light with small amplitude can be obtained by subtracting a photon from a squeezed vacuum state. In experiments this preparation c…

Self-cooling of a movable mirror to the ground state using radiation pressure

Aurelien Dantan, Claudiu Genes, David Vitali +1

We show that one can cool a micro-mechanical oscillator to its quantum ground state using radiation pressure in an appropriately detuned cavity (self-cooling). From a simple theory…

Trapped Bose gases with large positive scattering length

M. Thøgersen, D. V. Fedorov, A. S. Jensen

We calculate the energy and the condensate fraction of a system of trapped bosons interacting via a short-range two-body potential with positive scattering length. The potential is…

Conditional dynamics induced by new configurations for Rydberg dipole-dipole interactions

E. Brion, A. S. Mouritzen, K. Molmer

We suggest a novel way to use strong Rydberg dipole-dipole interactions in order to induce non-trivial conditional dynamics in individual-atom systems and mesoscopic ensembles. Con…
