Entanglement-verified time distribution in a metropolitan network
Mohammed K. Alqedra, Samuel Gyger, Katharina D. Zeuner +4
The precise synchronization of distant clocks is a fundamental requirement for a wide range of applications. Here, we experimentally demonstrate a novel approach of quantum clock s…
Coherent Quantum Interconnection between On-Demand Quantum Dot Single Photons and a Resonant Atomic Quantum Memory
Guo-Dong Cui, Lucas Schweickert, Klaus D. Jöns +11
Long-range quantum communication requires the development of in-out light-matter interfaces to achieve a quantum advantage in entanglement distribution. Ideally, these quantum inte…
Telecom-wavelength InAs QDs with low fine structure splitting grown by droplet epitaxy on GaAs(111)A vicinal substrates
A. Tuktamyshev, A. Fedorov, S. Bietti +8
We present self-assembly of InAs/InAlAs quantum dots by droplet epitaxy technique on vicinal GaAs(111)A substrates. The small miscut angle, while maintaining the symmetries imposed…
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…
Reconfigurable frequency coding of triggered single photons in the telecom C--band
Samuel Gyger, Katharina D. Zeuner, Klaus D. Jöns +7
In this work, we demonstrate reconfigurable frequency manipulation of quantum states of light in the telecom C-band. Triggered single photons are encoded in a superposition state o…
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…
Entanglement swapping with photons generated on-demand by a quantum dot
Francesco Basso Basset, Michele B. Rota, Christian Schimpf +8
Photonic entanglement swapping, the procedure of entangling photons without any direct interaction, is a fundamental test of quantum mechanics and an essential resource to the real…
Electromagnetically Induced Transparency of On-demand Single Photons in a Hybrid Quantum Network
Lucas Schweickert, Klaus D. Jöns, Mehdi Namazi +11
Long range quantum communication and quantum information processing require the development of light-matter interfaces for distributed quantum networks. Even though photons are ide…
Bright single InAsP quantum dots at telecom wavelengths in position-controlled InP nanowires: the role of the photonic waveguide
Sofiane Haffouz, Dan Dalacu, Philip J. Poole +6
We report on the site-selected growth of bright single InAsP quantum dots embedded within InP photonic nanowire waveguides emitting at telecom wavelengths. We demonstrate a dramati…
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…
