Coexistence of weak and strong coupling with a quantum dot in a photonic molecule
S. Lichtmannecker, M. Kaniber, S. Echeverri-Arteaga +12
We study the emission from a molecular photonic cavity formed by two proximal photonic crystal defect cavities containing a small number (<3) of In(Ga)As quantum dots. Under strong…
Coulomb mediated hybridization of excitons in artificial molecules
P. -L. Ardelt, K. Gawarecki, K. Müller +11
We report the Coulomb mediated hybridization of excitonic states in an optically active, artificial quantum dot molecule. By probing the optical response of the artificial molecule…
Controlled tunneling induced dephasing of Rabi rotations for ultra-high fidelity hole spin initialization
P. L. Ardelt, T. Simmet, K. Müller +6
We report the sub-picosecond initialization of a single heavy hole spin in a self-assembled quantum dot with >98.5 % fidelity and without external magnetic field. Using an opticall…
Independent dynamic acousto-mechanical and electrostatic control of individual quantum dots in a LiNbO-GaAs hybrid
J. Pustiowski, K. Müller, M. Bichler +4
We demonstrate tuning of single quantum dot emission lines by the combined action of the dynamic acoustic field of a radio frequency surface acoustic wave and a static electric fie…
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.…
Surface acoustic wave controlled charge dynamics in a thin InGaAs quantum well
Florian J. R. Schülein, Jens Pustiowski, Kai Müller +5
We experimentally study the optical emission of a thin quantum well and its dynamic modulation by a surface acoustic wave (SAW). We observe a characteristic transition of the modul…
