Harnessing the spectral correlations also permits refinement of the emission and unraveling of previously hidden strong correlations in a plethora of quantum-optical systems under continuous-wave excitation. In this work, we investigate such correlations for time-dependent excitation and develop a methodology to compute efficiently time-integrated correlations, which are at the heart of the photon-counting theory, and subsequently apply it to analyze the photon emission of pulsed systems. By combining this formalism with the —which facilitates frequency-resolved correlations—we demonstrate how spectral filtering enhances single-photon purity and suppresses multiphoton noise in time-bin-encoded quantum states. Specifically, filtering the central spectral peak of a dynamically driven two-level system boosts temporal coherence and improves the fidelity of time-bin entanglement preparation, even under conditions favoring multiphoton emission. These results establish spectral filtering as a critical tool for tailoring photon statistics in pulsed quantum light sources.</jats:p>"}],"date_created":"2025-12-04T12:19:04Z","type":"journal_article","department":[{"_id":"623"},{"_id":"15"},{"_id":"429"},{"_id":"642"}],"title":"Spectral correlations of dynamical resonance fluorescence","year":"2025","author":[{"full_name":"Bermúdez-Feijóo, Santiago","last_name":"Bermúdez-Feijóo","first_name":"Santiago"},{"last_name":"Zubizarreta Casalengua","first_name":"Eduardo","full_name":"Zubizarreta Casalengua, Eduardo"},{"full_name":"Müller, Kai","last_name":"Müller","first_name":"Kai"},{"id":"85353","full_name":"Jöns, Klaus","last_name":"Jöns","first_name":"Klaus"}],"publication_identifier":{"issn":["2643-1564"]},"publication_status":"published","date_updated":"2025-12-11T12:52:24Z","intvolume":"         7","article_number":"033296","language":[{"iso":"eng"}],"doi":"10.1103/jmy9-bd3l","citation":{"short":"S.

In this study, the atomic‐scale electric field and charge density distribution of WSe<jats:sub>2</jats:sub> bi‐ and trilayers are revealed using an emerging microscopy technique, differential phase contrast (DPC) imaging in scanning transmission electron microscopy (STEM). For pristine material, a higher positive charge density located at the selenium atomic columns compared to the tungsten atomic columns is obtained and tentatively explained by a coherent scattering effect. Furthermore, the change in the electric field distribution induced by a missing selenium atomic column is investigated. A characteristic electric field distribution in the vicinity of the defect with locally reduced magnitudes compared to the pristine lattice is observed. This effect is accompanied by a considerable inward relaxation of the surrounding lattice, which according to first principles DFT calculation is fully compatible with a missing column of Se atoms. This shows that DPC imaging, as an electric field sensitive technique, provides additional and remarkable information to the otherwise only structural analysis obtained with conventional STEM imaging.</jats:p>"}],"project":[{"_id":"53","name":"TRR 142: TRR 142 - Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"},{"_id":"54","name":"TRR 142 - A: TRR 142 - Project Area A"},{"name":"TRR 142 - B: TRR 142 - Project Area B","_id":"55"},{"_id":"166","name":"TRR 142 - A11: TRR 142 - Subproject A11"},{"_id":"168","name":"TRR 142 - B07: TRR 142 - Polaronen-Einfluss auf die optischen Eigenschaften von Lithiumniobat (B07*)"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"date_created":"2024-06-24T09:46:25Z","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"790"},{"_id":"642"},{"_id":"286"},{"_id":"429"},{"_id":"230"},{"_id":"27"},{"_id":"35"},{"_id":"169"}]},{"volume":7,"user_id":"48188","_id":"62853","publisher":"Wiley","status":"public","citation":{"bibtex":"@article{Boos_Sbresny_Kim_Kremser_Riedl_Bopp_Rauhaus_Scaparra_Jöns_Finley_et al._2024, title={Coherent Swing‐Up Excitation for Semiconductor Quantum Dots}, volume={7}, DOI={<a href=\"https://doi.org/10.1002/qute.202300359\">10.1002/qute.202300359</a>}, number={42300359}, journal={Advanced Quantum Technologies}, publisher={Wiley}, author={Boos, Katarina and Sbresny, Friedrich and Kim, Sang Kyu and Kremser, Malte and Riedl, Hubert and Bopp, Frederik W. and Rauhaus, William and Scaparra, Bianca and Jöns, Klaus and Finley, Jonathan J. and et al.}, year={2024} }","chicago":"Boos, Katarina, Friedrich Sbresny, Sang Kyu Kim, Malte Kremser, Hubert Riedl, Frederik W.

While various methods have been proposed and explored, they all have specific advantages and disadvantages. This study investigates the dynamics of the recent swing‐up scheme as an excitation method for a two‐level system and its performance in single‐photon generation. By applying two far red‐detuned laser pulses, the two‐level system can be prepared in the excited state with near‐unity fidelity. The successful operation and coherent character of this technique are demonstrated using a semiconductor quantum dot (QD). Moreover, the multi‐dimensional parameter space of the two laser pulses is explored to analyze its impact on excitation fidelity. Finally, the performance of the scheme as an excitation method for generating high‐quality single photons is analyzed. The swing‐up scheme itself proves effective, exhibiting nearly perfect single‐photon purity, while the observed indistinguishability in the studied sample is limited by the influence of the inevitable high excitation powers on the semiconductor environment of the quantum dot.</jats:p>"}],"publication":"Advanced Quantum Technologies","issue":"4"},{"language":[{"iso":"eng"}],"_id":"62858","user_id":"48188","author":[{"first_name":"L.","last_name":"Hanschke","full_name":"Hanschke, L."},{"first_name":"T.

As one of the most prominent consequences, this leads to the reappearance of Rabi rotations for increasing pulse power, which was theoretically predicted in Phys. Rev. Lett. 98, 227403 (2007).

Semiconductor quantum dots (QDs) are attractive candidates that emit high-quality quantum states of light on demand, however at a rate limited by their spontaneous radiative lifetime. In this study, we utilize the Purcell effect to demonstrate up to a 38-fold enhancement in the emission rate of InAs QDs by coupling them to metal-clad GaAs nanopillars. These cavities, featuring a sub-wavelength mode volume of 4.5x10-4 (λ/n)3 and low quality factor of 62, enable Purcell-enhanced single-photon emission across a large bandwidth of 15 nm. The broadband nature of the cavity eliminates the need for implementing tuning mechanisms typically required to achieve QD-cavity resonance, thus relaxing fabrication constraints. Ultimately, this QD-cavity architecture represents a significant stride towards developing solid-state quantum emitters generating near-ideal single-photon states at GHz-level repetition rates.","lang":"eng"}],"citation":{"bibtex":"@article{Jöns_2024, title={Purcell-enhanced single-photon emission from InAs/GaAs quantum dots coupled to broadband cylindrical nanocavities}, author={Jöns, Klaus}, year={2024} }","ama":"Jöns K.

To that end, we demonstrate active gating of an SNSPD with a minimum off-to-on rise time of 2.4 ns and a total gate length of 5.0 ns. We show how the rise time depends on the inductance of the detector in combination with the control electronics. The gate window is demonstrated to be fully and freely, electrically tunable up to 500 ns at a repetition rate of 1.0 MHz, as well as ungated, free-running operation. Control electronics to generate the gating are mounted on the 2.3 K stage of a closed-cycle sorption cryostat, while the detector is operated on the cold stage at 0.8 K. We show that the efficiency and timing jitter of the detector is not altered during the on-time of the gating window.

Ideally, one strives for a hybrid network architecture,\r\nwhich will consist of different quantum systems, combining the strengths of\r\neach system. However, interfacing different quantum systems via photonic\r\nchannels remains a major challenge because a detailed understanding of the\r\nunderlying light-matter interaction is missing. Here, we show the coherent\r\nmanipulation of single photons generated on-demand from a semiconductor quantum\r\ndot using a rubidium vapor quantum memory, forming a hybrid quantum network. We\r\ndemonstrate the engineering of the photons' temporal wave function using\r\nfour-level atoms and the creation of a new type of electromagnetic induced\r\ntransparency for quantum dot photons on resonance with rubidium transitions.\r\nGiven the short lifetime of our quantum dot transition the observed dynamics\r\ncannot be explained in the established steady-state picture. Our results play a\r\npivotal role in understanding quantum light-matter interactions at short time\r\nscales. These findings demonstrate a fundamental active node to construct\r\nfuture large-scale hybrid quantum networks.","lang":"eng"}],"external_id":{"arxiv":["1808.05921"]},"date_created":"2023-02-13T11:25:45Z","type":"preprint","department":[{"_id":"642"}],"status":"public","year":"2018","title":"Electromagnetically Induced Transparency of On-demand Single Photons in  a Hybrid Quantum Network","author":[{"full_name":"Schweickert, Lucas","last_name":"Schweickert","first_name":"Lucas"},{"id":"85353","full_name":"Jöns, Klaus D.","last_name":"Jöns","first_name":"Klaus D."},{"first_name":"Mehdi","last_name":"Namazi","full_name":"Namazi, Mehdi"},{"full_name":"Cui, Guodong","last_name":"Cui","first_name":"Guodong"},{"full_name":"Lettner, Thomas","last_name":"Lettner","first_name":"Thomas"},{"last_name":"Zeuner","first_name":"Katharina D.","full_name":"Zeuner, Katharina D."},{"first_name":"Lara Scavuzzo","last_name":"Montaña","full_name":"Montaña, Lara Scavuzzo"},{"first_name":"Saimon Filipe Covre da","last_name":"Silva","full_name":"Silva, Saimon Filipe Covre da"},{"last_name":"Reindl","first_name":"Marcus","full_name":"Reindl, Marcus"},{"first_name":"Huiying","last_name":"Huang","full_name":"Huang, Huiying"},{"full_name":"Trotta, Rinaldo","first_name":"Rinaldo","last_name":"Trotta"},{"last_name":"Rastelli","first_name":"Armando","full_name":"Rastelli, Armando"},{"full_name":"Zwiller, Val","last_name":"Zwiller","first_name":"Val"},{"full_name":"Figueroa, Eden","last_name":"Figueroa","first_name":"Eden"}],"date_updated":"2023-02-13T11:27:52Z","_id":"42048","language":[{"iso":"eng"}],"user_id":"14931"}]
