  • Date: Dec 6, 2016
  • Time: 02:30 PM - 03:30 PM (Local Time Germany)
  • Speaker: Prof. Dr. Vahid Sandoghdar, MPI für die Physik des Lichts, Erlangen
  • Room: Herbert Walther Lecture Hall
  • Host: MPQ
I plan to start this presentation with an overview of our work over the past decade on the efficient coupling of light and single quantum emitters, leading to the single-photon communication of two individual molecules at long distances [1].

In this context, we will also discuss new results on the detection of single rare earth ions [2], a high-efficiency triggered source of single photons [3] and coherent nonlinear optical phenomena, which let a single organic molecule act as an efficient switch for weak beams of light [4]. The long-term goal of these projects is to establish a platform for nano-quantum-optical operations and cooperative interactions in a mesoscopic system of photons and quantum emitters [5, 6]. In order to achieve this, we have developed a novel microcavity [7] and chip-based nanoguide circuitry [8] for use at cryogenic conditions.
