DESCRIPTION:Prof. Peter Lodahl\, Niels Bohr Institute\, University of Cope
 nhagen\nSemiconductor quantum dots have improved their optical performance
  dramatically in recent years\, and today a clear pathway is laid out for 
 constructing a deterministic and coherent photon-emitter interface by embe
 dding quantum dots in photonic nanostructures [1]. Such an interface can b
 e employed as an on-demand single-photon source for quantum-information ap
 plications\, but more generally enables single-photon nonlinearities and d
 eterministic quantum gates [2]. We will review the recent experimental pro
 gress on quantum dots coupled to nanophotonic waveguides and cavities enab
 ling unique ways of engineering light-matter interaction. A single-photon 
 coupling efficiency exceeding 98.4% is reported [3] and the indistinguisha
 bility of the emitted photons is extracted [4] and the fundamental limits 
 exploited [5]. Furthermore\, various out-coupling strategies for efficient
 ly transferring single photons to an optical fiber are implemented [6]. Th
 e unique engineering potential of the nanophotonic waveguides is demonstra
 ted by implementing a chiral quantum interface [7\,8]. The prospects and a
 pplications of single-photon nonlinearities [9\,10] and architectures for 
 scalable quantum networks are discussed [11].\n\n[1] Lodahl et al.\, Rev.
