We present experiments that study the interaction of single Barium ions with single photons and weak coherent fields in front of high-numerical aperture optical elements.
First, we show the experimental observation of the ion as the optical mirror of a Fabry-Perot cavity. This was achieved by tightly focussing a laser field onto the ion trapped in front of a far-distant dielectric mirror. We then demonstrate the very first steps towards entanglement of two far-distant ions using only single-photon detection events. Last, we will present our current efforts in the design of ion traps with even higher numerical aperture objectives and mirrors for efficient single photon collection and high entanglement rates.
