Phonon-assisted robust and deterministic two-photon biexciton preparation in a quantum dot
S. Bounouar, M. Müller, A. M. Barth +3
We investigate both experimentally and theoretically a simple yet more robust and flexible alternative to Rabi oscillation-type biexciton preparation protocols traditionally used f…
Polarization fine-structure and enhanced single-photon emission of self-assembled lateral InGaAs quantum dot molecules embedded in a planar micro-cavity
C. Hermannstädter, M. Witzany, G. J. Beirne +8
Single lateral InGaAs quantum dot molecules have been embedded in a planar micro-cavity in order to increase the luminescence extraction efficiency. Using a combination of metal-or…
Deterministic Storage and Retrieval of Telecom Quantum Dot Photons Interfaced with an Atomic Quantum Memory
S. E. Thomas, L. Wagner, R. Joos +11
A hybrid interface of solid state single-photon sources and atomic quantum memories is a long sought-after goal in photonic quantum technologies. Here we demonstrate deterministic…
Efficient single-photon emission from electrically driven InP quantum dots epitaxially grown on Si(001)
M. Wiesner, W. -M. Schulz, C. Kessler +4
The heteroepitaxy of III-V semiconductors on silicon is a promising approach for making silicon a photonic platform for on-chip optical interconnects and quantum optical applicatio…
Coherence and indistinguishability of highly pure single photons from non-resonantly and resonantly excited telecom C-band quantum dots
C. Nawrath, F. Olbrich, M. Paul +3
In the present work, the effect of resonant pumping schemes in improving the photon coherence is investigated on InAs/InGaAs/GaAs quantum dots emitting in the telecom C-band. The l…
Reducing vortex losses in superconducting microwave resonators with microsphere patterned antidot arrays
D. Bothner, C. Clauss, E. Koroknay +8
We experimentally investigate the vortex induced energy losses in niobium coplanar waveguide resonators with and without quasihexagonal arrays of nanoholes (antidots), where large-…
