Wave form and spectral properties of single photons emitted by a single atom — •Tristan Tentrup, Jürgen Eschner, and Giovanna Morigi — Saarland University, Saarbrücken, Germany

Quantum networks require the controlled interaction of stationary and flying qubits, implemented for example by single ions that emit [1] and absorb [2] single photons. This requires the characterization and the possibility to tailor the wave form and spectrum of the photons emitted by single emitters. The wave packet and Fourier spectrum of a photon emitted by a single atom is theoretically characterized under several conditions. We consider in particular the situation when the atom is driven by a laser pulse of different spectral forms, or when it is excited by a single photon generated by a second emitter.
