Abstract

Rydberg atoms in dc electric fields acquire static dipole moments. When the atoms are close to a surface producing an inhomogeneous electric field, such as by the adsorbates on an atom chip, depending on the sign of the dipole moment of the Rydberg-Stark eigenstate, the atoms may experience a force toward or away from the surface. We show that by applying a bias electric field and coupling a desired Rydberg state by a microwave field of proper frequency to another Rydberg state with opposite sign of the dipole moment, we can create a trapping potential for the atom at a prescribed distance from the surface. Perfectly overlapping trapping potentials for several Rydberg states can also be created by multicomponent microwave fields. A pair of such trapped Rydberg states of an atom can represent a qubit. Finally, we discuss an optimal realization of the SWAP gate between pairs of such atomic Rydberg qubits separated by a large distance but interacting with a common mode of a planar microwave resonator at finite temperature.

  21. Due to small polarizability of the atoms in the ground electronic state, they are largely immune to mechanical forces in static, spatially inhomogeneous electric fields F of moderate strengths and can be trapped by dipole forces induced by focused laser beams that form optical tweezers. In contrast, for strongly polarizable Rydberg states of the atoms, the mechanical forces ∇(dr|F|) are so large that typical optical dipole potentials cannot trap the Rydberg atoms in such inhomogeneous electric fields F.
