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…
Electrically-Pumped Wavelength-Tunable GaAs Quantum Dots Interfaced with Rubidium Atoms
Huiying Huang, Rinaldo Trotta, Yongheng Huo +9
We demonstrate the first wavelength-tunable electrically-pumped source of non-classical light that can emit photons with wavelength in resonance with the D2 transitions of 87Rb ato…
Scalable Sources of Entangled Photons with Wavelength on Demand
Rinaldo Trotta, Javier Martin-Sanchez, Johannes S. Wildmann +8
The prospect of using the quantum nature of light for secure communication keeps spurring the search and investigation of suitable sources of entangled-photons. Semiconductor quant…
Atomic Clouds as Spectrally-Selective and Tunable Delay Lines for Single Photons from Quantum Dots
Johannes S. Wildmann, Rinaldo Trotta, Javier Martín-Sánchez +3
We demonstrate a compact, spectrally-selective, and tunable delay line for single photons emitted by quantum dots. This is achieved by fine-tuning the wavelength of the optical tra…
Highly entangled photons from hybrid piezoelectric-semiconductor quantum dot devices
Rinaldo Trotta, Johannes S. Wildmann, Eugenio Zallo +2
Entanglement resources are key ingredients of future quantum technologies. If they could be efficiently integrated into a semiconductor platform a new generation of devices could b…
All optical quantum control of a spin-quantum state and ultrafast transduction into an electric current
K. Müller, T. Kaldewey, R. Ripszam +6
The ability to control and exploit quantum coherence and entanglement drives research across many fields ranging from ultra-cold quantum gases to spin systems in condensed matter.…
High fidelity optical preparation and coherent Larmor precession of a single hole in an InGaAs quantum dot molecule
K. Müller, A. Bechtold, C. Ruppert +8
We employ ultrafast pump-probe spectroscopy with photocurrent readout to directly probe the dynamics of a single hole spin in a single, electrically tunable self-assembled quantum…
