  • Fully on-chip photonic turnkey quantum source for entangled qubit/qudit state generation 
    Mahmudlu, Hatam; Johanning, Robert; van Rees, Albert; Khodadad Kashi, Anahita; Epping, Jörn P.; Haldar, Raktim; Boller, Klaus-J.; Kues, Michael (London [u.a.] : Nature Publ. Group, 2023)
    Integrated photonics has recently become a leading platform for the realization and processing of optical entangled quantum states in compact, robust and scalable chip formats, with applications in long-distance quantum-secured ...
  • High efficiency grating couplers for strain tunable GaAs quantum dot based entangled photon sources 
    Schmidt, Constantin; Ma, Chenxi; Benthin, Frederik; Yang, Jingzhong; Rugeramigabo, Eddy P.; Zopf, Michael; Ding, Fei (New York, NY : American Inst. of Physics, 2024)
    The on-chip integration of single photon and entangled photon emitters such as epitaxially grown semiconductor quantum dots into photonic frameworks is a rapidly evolving research field. GaAs quantum dots offer high purity ...
  • Local droplet etching on InAlAs/InP surfaces with InAl droplets 
    Cao, Xin; Zhang, Yiteng; Ma, Chenxi; Wang, Yinan; Brechtken, Benedikt; Haug, Rolf J.; Rugeramigabo, Eddy P.; Zopf, Michael; Ding, Fei (New York, NY : American Inst. of Physics, 2022)
    GaAs quantum dots (QDs) grown by local droplet etching (LDE) have been studied extensively in recent years. The LDE method allows for high crystallinity, as well as precise control of the density, morphology, and size of ...
  • Non-equilibrium spin noise spectroscopy of a single quantum dot operating at fiber telecommunication wavelengths 
    Sun, Tian-Jiao; Sterin, P.; Lengert, L.; Nawrath, C.; Jetter, M.; Michler, P.; Ji, Yang; Hübner, J.; Oestreich, M. (Melville, NY : American Inst. of Physics, 2022)
    We report on the spin and occupation noise of a single, positively charged (InGa)As quantum dot emitting photons in the telecommunication C-band. The spin noise spectroscopy measurements are carried out at a temperature ...
  • Piezoelectric screening in single InAs/AlAs quantum dots 
    Sarkar, D.; Van Der Meulen, H.P.; Calleja, J.M.; Meyer, J.M.; Haug, Rolf J.; Pierz, Klaus (College Park, MD : American Institute of Physics, 2009)
    Micro-photoluminescence spectroscopy for varying temperature, excitation intensity and energy was performed on a single InAs/AlAs self-assembled quantum dot. A broad sideband at 1.2 meV of the zero phonon line is attributed ...
  • Single photon emission from ODT passivated near-surface GaAs quantum dots 
    Cao, Xin; Yang, Jingzhong; Li, Pengji; Zhang, Yiteng; Rugeramigabo, Eddy P.; Brechtken, Benedikt; Haug, Rolf J.; Zopf, Michael; Ding, Fei (Melville, NY : American Inst. of Physics, 2021)
    Epitaxially grown semiconductor quantum dots are promising candidates for pure single photon and polarization-entangled photon pair emission. Excellent optical properties can typically be ensured only if these so-called ...
  • Temperature-dependent broadening of coherent current peaks in InAs double quantum dots 
    Dani, Olfa; Hussein, Robert; Bayer, Johannes C.; Kohler, Sigmund; Haug, Rolf J. (London : Springer Nature, 2022)
    Quantum systems as used for quantum computation or quantum sensing are nowadays often realized in solid state devices as e.g. complex Josephson circuits or coupled quantum-dot systems. Condensed matter as an environment ...
