Tunable g-Factors of Hybridized Orbitals in a Quantum Dot Molecule
Michelle Lienhart, Krzysztof Gawarecki, Pavel Daskalov +10
The ability to control the -factors of orbital spin states in optically active quantum dot molecules (QDMs) is a prerequisite for the high-fidelity generation of multi-photonic…
Impact of Stoichiometry of MoSi Thin Films for Enhanced Sensitivity of Superconducting Nanowire Single-Photon Detectors
Stefanie Grotowski, Damjan Pecijareski, Hadrien Le Petit Delacour +8
We report on the impact of the stoichiometry of superconducting MoSi thin films on the performance of superconducting nanowire single-photon detectors (SNSPDs). Specifically, we in…
Molecular beam epitaxy of wafer-scale O-band InAs/InGaAs quantum dots on GaAs for quantum photonics
Pavel S. Avdienko, Lukas Hanschke, Quirin Buchinger +13
We report a scalable molecular beam epitaxy strategy to achieve a low density of O-band electrically tunable InAs/InGaAs quantum dots (QDs) on GaAs(001) substrates. Our approach is…
Ultra-slow orbital and spin dynamics in an electrically tunable quantum dot molecule
Christopher Thalacker, Michelle Lienhart, Markus Stöcker +13
Tunnel-coupled optically active quantum dot molecules (QDMs), have the potential to operate as spin-photon-interfaces with coupled spins that interact with two different photon fre…
Mitigating the Transition of SiV in Diamond to an Optically Dark State
Manuel Rieger, Rubek Poudel, Tobias Waldmann +7
Negatively charged silicon vacancy centers in diamond (SiV) are promising for quantum photonic technologies. However, when subject to resonant optical excitation, they can inad…
Single-Photon Detection in Few-Layer NbSe Superconducting Nanowires
Lucio Zugliani, Alessandro Palermo, Bianca Scaparra +11
Superconducting Nanowire Single-Photon Detectors (SNSPDs) are key building blocks for photonic quantum technologies due to their ability to detect single photons with ultra-high ef…
