  [Institut Quantique] Séminaire IQ – Reiko Yamada

  Location : Description : Reiko YamadaInvitée de Mathieu MassicotteCompositrice et postdocInstitut des sciences photoniques (ICFO), BarcleoneDr. Reiko Yamada is a composer, sound artist and postdoctoral research fellow at Institute for Photonic Sciences (ICFO) in Barcelona, Spain.She is currently conducting an interdisciplinary research project in collaboration with Prof. Dr. Maciej Lewenstein entitled Of Randomness and Imperfection. In this talk, Dr. Yamada will discuss how the team has been attempting to produce sound timbres from the genuine quantum true randomness which so far culminated into research paper, musical scores and performance involving live musicians at Barcelona’s Sonar Festival.

  [Institut Quantique] Séminaire IQ – Antoine Reserbat-Plantey

  Location : Description : Antoine Reserbat-PlanteyInvité de Mathieu MassicotteChercheur au CNRS – CRHEA, Valbonne, FranceAbstractThe field of two-dimensional (2D) materials-basednanophotonics has been growing at a rapid pace, triggered by the ability todesign nanophotonic systems with in situ control, unprecedented number ofdegrees of freedom, and to build material heterostructures from the bottom upwith atomic precision [1]. A wide palette of polaritonic classes have beenidentified, comprising ultraconfined optical fields, even approachingcharacteristic length-scales of a single atom. These advances have been a realboost for the emerging field of quantum nanophotonics, enabling quantumtechnologies harnessing single-photon generation, manipulation, and detectionusing 2D materials. In my talk, I will show several hybrid systems consistingin lifetime-limited single emitters [2, 3] (linewidth ~ 40 MHz) and 2Dmaterials at sub-wavelength separation without degradation of the emissionproperties [4]. We have demonstrated that their nanoscale dimensions enableultra-broadband tuning (tuning range > 400 GHz) and fast modulation (frequency~ 100 MHz) of the emission energy [5], which renders it an integrated,ultra-compact tuneable SPS. I will also present recent results on unusual Starktuning of ultra-narrow quantum emitter located at the edge of a graphenetransistor and electrostatic engineering of excitons in 2D semiconductors.References[1] A.
