Giant Rydberg excitons in CuO probed by photoluminescence excitation spectroscopy
Marijn A. M. Versteegh, Stephan Steinhauer, Josip Bajo +7
Rydberg excitons are, with their ultrastrong mutual interactions, giant optical nonlinearities, and very high sensitivity to external fields, promising for applications in quantum…
The crux of using the cascaded emission of a 3-level quantum ladder system to generate indistinguishable photons
Eva Schöll, Lucas Schweickert, Lukas Hanschke +13
We investigate the degree of indistinguishability of cascaded photons emitted from a 3-level quantum ladder system; in our case the biexciton-exciton cascade of semiconductor quant…
The Origin of Antibunching in Resonance Fluorescence
Lukas Hanschke, Lucas Schweickert, Juan Camilo López Carreño +14
Epitaxial quantum dots have emerged as one of the best single-photon sources, not only for applications in photonic quantum technologies but also for testing fundamental properties…
On-demand generation of entangled photon pairs in the telecom C-band for fiber-based quantum networks
Katharina D. Zeuner, Klaus D. Jöns, Lucas Schweickert +9
On-demand sources of entangled photons for the transmission of quantum information in the telecom C-band are required to realize fiber-based quantum networks. So far, non-determini…
Proximitized Josephson junctions in highly-doped InAs nanowires robust to optical illumination
Lily Yang, Stephan Steinhauer, Elia Strambini +7
We have studied the effects of optical-frequency light on proximitized InAs/Al Josephson junctions based on highly n-doped InAs nanowires at varying incident photon flux and at thr…
Resonance fluorescence of GaAs quantum dots with near-unity photon indistinguishability
Eva Schöll, Lukas Hanschke, Lucas Schweickert +10
Photonic quantum technologies call for scalable quantum light sources that can be integrated, while providing the end user with single and entangled photons on-demand. One promisin…
A stable wavelength-tunable triggered source of single photons and cascaded photon pairs at the telecom C-band
Katharina D. Zeuner, Matthias Paul, Thomas Lettner +8
The implementation of fiber-based long-range quantum communication requires tunable sources of single photons at the telecom C-band. Stable and easy-to-implement wavelength- tunabi…
On-demand generation of background--free single photons from a solid-state source
Lucas Schweickert, Klaus D. Jöns, Katharina D. Zeuner +8
True on--demand high--repetition--rate single--photon sources are highly sought after for quantum information processing applications. However, any coherently driven two-level quan…
Bright nanoscale source of deterministic entangled photon pairs violating Bell's inequality
Klaus D. Jöns, Lucas Schweickert, Marijn A. M. Versteegh +6
Global, secure quantum channels will require efficient distribution of entangled photons. Long distance, low-loss interconnects can only be realized using photons as quantum inform…
