Slow and fast light behavior of single photons from a quantum dot interacting with the excited state hyperfine structure of the Cesium D1-line
Tim Kroh, Janik Wolters, Andreas Ahlrichs +9
Hybrid interfaces between distinct quantum systems play a major role in the implementation of quantum networks. Quantum states have to be stored in memories to synchronize the phot…
Strain-Tuning of the Optical Properties of Semiconductor Nanomaterials by Integration onto Piezoelectric Actuators
Javier Martin-Sanchez, Rinaldo Trotta, Antonio Mariscal +13
The tailoring of the physical properties of semiconductor nanomaterials by strain has been gaining increasing attention over the last years for a wide range of applications such as…
Inversion of the exciton built-in dipole moment in In(Ga)As quantum dots via nonlinear piezoelectric effect
Johannes Aberl, Petr Klenovský, Johannes S. Wildmann +6
We show that anisotropic biaxial stress can be used to tune the built-in dipole moment of excitons confined in In(Ga)As quantum dots up to complete erasure of its magnitude and inv…
Highly indistinguishable and strongly entangled photons from symmetric GaAs quantum dots
Daniel Huber, Marcus Reindl, Yongheng Huo +5
The development of scalable sources of non-classical light is fundamental to unlock the technological potential of quantum photonics\cite{Kimble:Nat2008}. Among the systems under i…
