Progress towards a dual species atomic quantum repeater node using a high-finesse fiber resonator

POSTER

Abstract

We present work towards a quantum repeater node based on the use of a high-finesse fiber cavity with atoms of two atomic species. Excellent coupling between the cavity and propagating light modes, and entanglement swapping between Rb and Cs atoms within the cavity, will allow the repeater to be operated with high efficiency and long memory lifetimes. In an intermediate implementation, ensembles of Rb atoms will be transported into the cavity and used for studies of the effects of surface charges on Rydberg excitation fidelities. Here we report on our progress in the use of an optical conveyor to transport atoms from a magneto-optical trap into the field mode of a high-finesse fiber cavity.
