Consequences of Zeeman Degeneracy for van der Waals Blockade between Rydberg Atoms
Thad G. Walker, M. Saffman
We analyze the effects of Zeeman degeneracies on the long-range interactions between like Rydberg atoms, with particular emphasis on applications to quantum information processing…
Rabi flopping between ground and Rydberg states with dipole-dipole atomic interactions
T. A. Johnson, E. Urban, T. Henage +4
We demonstrate Rabi flopping of small numbers of atoms between ground and Rydberg states with . Coherent population oscillations are observed for single ato…
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…
Quantum computing with collective ensembles of multi-level systems
E. Brion, K. Moelmer, M. Saffman
We propose a new physical approach for encoding and processing of quantum information in ensembles of multi-level quantum systems, where the different bits are not carried by indiv…
