Michael Schug, Christoph Kurz, Pascal Eich, Jan Huwer, Philipp Müller, Jürgen Eschner · Physical Review A · 2014
High-contrast quantum beats in the single-photon scattering probability of a single atomic ion are experimentally observed and controlled, highlighting two distinct physical mechanisms, the interference in absorption and in emission.
