Spectroscopy of a single molecule with a stream of lifetime-limited single photons — Yves Rezus, •Samuel Walt, Gert Zumofen, Alois Renn, Stephan Götzinger, and Vahid Sandoghdar — ETH Zürich, Laboratory of Physical Chemistry (LPC), 8093 Zürich, Switzerland

An important elementary process in quantum information processing is the transfer of a single excitation between two quantum emitters. We report on the first realization of such an experiment in a direct fashion, where lifetime-limited single photons emitted by a single molecule are used as the source for the coherent excitation and spectroscopy of a second single molecule at a distance of more than 2m.
