Rydberg atoms in Bose-Einstein condensates and optical latticesMatthieu Viteau1, Jagoda Radogostowicz1, Mark Bason1, Nicola Malossi1, Amodsen Chotia2, Donatella Ciampini1, •Oliver Morsch2, and Ennio Arimondo1,21CNISM UdR Pisa, Dipartimento di Fisica, Largo Pontecorvo 3, 56127 Pisa, Italy — 2CNR-INFM, Largo Pontecorvo 3, 56127 Pisa, Italy

We report on progress in exciting Rydberg states of Rubidium atoms in the Bose condensed phase and inside optical lattices. The high densities achievable in Bose-Einstein condensates give us access to a regime where dipole-dipole interactions between Rydberg atoms are strong, and the spatial order in optical lattices fixes a length scale for the interatomic distance. Both ingredients are essential for implementing controlled Rydberg-Rydberg interactions for quantum gates.
