Wave-mixing experiments are often described with semiclassical models, where the light is modeled classically and the material quantum mechanically. Here, however, we use a fully quantized model, where the light is given by a quantum state of light. Quantum light involves more degrees of freedom than classical light as e.g., its photon statistics and quantum correlations, which is a promising resource for quantum devices, such as quantum memories. The light-matter interaction is treated with a Jaynes-Cummings type model and the quantum field is given by a single mode since the quantum dots are embedded in a microcavity. We present numerical simulations of the four-wave-mixing response of a homogeneous system for pulse sequences and find a significant dependence of the result on the photon statistics of the incident pulses. The model constitutes a problem with a large state space which arises from the frequency distribution of the transition energies of the inhomogeneously broadened quantum dot ensemble that is coupled with a quantum light mode. Here we approximate the dynamics by summing over individual quantum dot-microcavity systems. Photon echoes arising from the excitation with different quantum states of light are simulated and compared.","lang":"eng"}],"publication":"Ultrafast Phenomena and Nanophotonics XXVII","title":"Theoretical analysis of four-wave mixing on semiconductor quantum dot ensembles with quantum light","publisher":"SPIE","date_created":"2023-03-29T20:28:20Z","year":"2023"},{"file_date_updated":"2023-07-06T06:40:28Z","article_number":"3915","user_id":"30525","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"_id":"45868","status":"public","type":"journal_article","main_file_link":[{"open_access":"1"}],"doi":"10.1038/s41467-023-39599-8","author":[{"first_name":"Hammad","full_name":"Ahmed, Hammad","last_name":"Ahmed"},{"first_name":"Muhammad Afnan","last_name":"Ansari","full_name":"Ansari, Muhammad Afnan"},{"last_name":"Li","full_name":"Li, Yan","first_name":"Yan"},{"last_name":"Zentgraf","orcid":"0000-0002-8662-1101","id":"30525","full_name":"Zentgraf, Thomas","first_name":"Thomas"},{"first_name":"Muhammad Qasim","full_name":"Mehmood, Muhammad Qasim","last_name":"Mehmood"},{"first_name":"Xianzhong","last_name":"Chen","full_name":"Chen, Xianzhong"}],"volume":14,"oa":"1","date_updated":"2023-07-06T06:42:10Z","citation":{"mla":"Ahmed, Hammad, et al. “Dynamic Control of Hybrid Grafted Perfect Vector Vortex Beams.” <i>Nature Communications</i>, vol. 14, no. 1, 3915, Springer Science and Business Media LLC, 2023, doi:<a href=\"https://doi.org/10.1038/s41467-023-39599-8\">10.1038/s41467-023-39599-8</a>.","bibtex":"@article{Ahmed_Ansari_Li_Zentgraf_Mehmood_Chen_2023, title={Dynamic control of hybrid grafted perfect vector vortex beams}, volume={14}, DOI={<a href=\"https://doi.org/10.1038/s41467-023-39599-8\">10.1038/s41467-023-39599-8</a>}, number={13915}, journal={Nature Communications}, publisher={Springer Science and Business Media LLC}, author={Ahmed, Hammad and Ansari, Muhammad Afnan and Li, Yan and Zentgraf, Thomas and Mehmood, Muhammad Qasim and Chen, Xianzhong}, year={2023} }","short":"H.

PVVBs are typically generated through the superposition of perfect vortex beams, which suffer from the limited number of topological charges (TCs). Furthermore, dynamic control of PVVBs is desirable and has not been reported. We propose and experimentally demonstrate hybrid grafted perfect vector vortex beams (GPVVBs) and their dynamic control. Hybrid GPVVBs are generated through the superposition of grafted perfect vortex beams with a multifunctional metasurface. The generated hybrid GPVVBs possess spatially variant rates of polarization change due to the involvement of more TCs. Each hybrid GPVVB includes different GPVVBs in the same beam, adding more design flexibility. Moreover, these beams are dynamically controlled with a rotating half waveplate. The generated dynamic GPVVBs may find applications in the fields where dynamic control is in high demand, including optical encryption, dense data communication, and multiple particle manipulation."}],"publication":"Nature Communications","title":"Dynamic control of hybrid grafted perfect vector vortex beams","date_created":"2023-07-06T06:34:37Z","publisher":"Springer Science and Business Media LLC","year":"2023","issue":"1","quality_controlled":"1"},{"author":[{"first_name":"Silia","orcid":"https://orcid.org/0000-0002-1568-2580","last_name":"Babel","full_name":"Babel, Silia","id":"63231"},{"last_name":"Bollmers","full_name":"Bollmers, Laura","id":"61375","first_name":"Laura"},{"last_name":"Massaro","orcid":"0000-0002-2539-7652","id":"59545","full_name":"Massaro, Marcello","first_name":"Marcello"},{"id":"36389","full_name":"Luo, Kai Hong","last_name":"Luo","orcid":"0000-0003-1008-4976","first_name":"Kai Hong"},{"full_name":"Stefszky, Michael","id":"42777","last_name":"Stefszky","first_name":"Michael"},{"first_name":"Federico","id":"88928","full_name":"Pegoraro, Federico","last_name":"Pegoraro"},{"first_name":"Philip","last_name":"Held","id":"68236","full_name":"Held, Philip"},{"first_name":"Harald","full_name":"Herrmann, Harald","id":"216","last_name":"Herrmann"},{"first_name":"Christof","full_name":"Eigner, Christof","id":"13244","orcid":"https://orcid.org/0000-0002-5693-3083","last_name":"Eigner"},{"id":"27150","full_name":"Brecht, Benjamin","orcid":"0000-0003-4140-0556 ","last_name":"Brecht","first_name":"Benjamin"},{"full_name":"Padberg, Laura","id":"40300","last_name":"Padberg","first_name":"Laura"},{"first_name":"Christine","last_name":"Silberhorn","full_name":"Silberhorn, Christine","id":"26263"}],"date_created":"2023-07-03T14:08:36Z","volume":31,"publisher":"Optica Publishing Group","date_updated":"2023-07-05T07:58:31Z","doi":"10.1364/oe.484126","title":"Demonstration of Hong-Ou-Mandel interference in an LNOI directional coupler","issue":"14","publication_status":"published","publication_identifier":{"issn":["1094-4087"]},"citation":{"mla":"Babel, Silia, et al. “Demonstration of Hong-Ou-Mandel Interference in an LNOI Directional Coupler.” <i>Optics Express</i>, vol. 31, no. 14, 23140, Optica Publishing Group, 2023, doi:<a href=\"https://doi.org/10.1364/oe.484126\">10.1364/oe.484126</a>.","short":"S.

The coupler has been designed and fabricated in house and provides close to perfect balanced beam splitting.

The optimized antennas possess a broadband nature and have a nearunity radiation efficiency at an operational wavelength of 780 nm.

An electrically addressable polarisation converter based on liquid crystals may be used to switch between the two states of polarisation, at which the light transmitted through the meta-lens is focused (trapping) or defocussed (releasing), respectively.","lang":"eng"}],"publication":"Liquid Crystals","type":"journal_article","language":[{"iso":"eng"}],"department":[{"_id":"313"},{"_id":"230"},{"_id":"638"},{"_id":"15"},{"_id":"623"}],"user_id":"30525","_id":"40513","project":[{"name":"TRR 142: TRR 142","_id":"53","grant_number":"231447078"},{"name":"TRR 142 - B: TRR 142 - Project Area B","_id":"55"},{"name":"TRR 142 - B09: TRR 142 - Effiziente Erzeugung mit maßgeschneiderter optischer Phaselage der zweiten Harmonischen mittels Quasi-gebundener Zustände in GaAs Metaoberflächen (B09*)","_id":"170","grant_number":"231447078"}]},{"status":"public","publication":"Physical Review Research","type":"journal_article","language":[{"iso":"eng"}],"article_number":"043158","department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"293"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"623"},{"_id":"27"}],"user_id":"55907","_id":"55900","project":[{"_id":"53","name":"TRR 142: TRR 142 - Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"},{"_id":"56","name":"TRR 142 - C: TRR 142 - Project Area C"},{"_id":"174","name":"TRR 142 - C10: TRR 142 -  Erzeugung und Charakterisierung von Quantenlicht in nichtlinearen Systemen: Eine theoretische Analyse (C10*)"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"intvolume":"         5","citation":{"ieee":"D.

In the present work, it focuses on the generation of pairs of photons with high degrees of polarization entanglement and simultaneously high indistinguishability. It achieves this goal by selectively reducing the biexciton lifetime with an optical resonator. It demonstrates that a suitably tailored circular Bragg reflector fulfills the requirements of sufficient selective Purcell enhancement of biexciton emission paired with spectrally broad photon extraction and twofold degenerate optical modes. The in‐depth theoretical study combines (i) the optimization of realistic photonic structures solving Maxwell's equations from which model parameters are extracted as input for (ii) microscopic simulations of quantum‐dot cavity excitation dynamics with full access to photon properties. It reports non‐trivial dependencies on system parameters and use the predictive power of the combined theoretical approach to determine the optimal range of Purcell enhancement that maximizes indistinguishability and entanglement to near unity values, here specifically for the telecom C‐band at 1550 nm.</jats:p>","lang":"eng"}],"publication":"Advanced Quantum Technologies","language":[{"iso":"eng"}]},{"publisher":"Optica Publishing Group","date_updated":"2025-09-12T11:41:42Z","volume":13,"date_created":"2025-09-12T11:40:26Z","author":[{"full_name":"Lüders, Carolin","last_name":"Lüders","first_name":"Carolin"},{"last_name":"Barkhausen","id":"63631","full_name":"Barkhausen, Franziska","first_name":"Franziska"},{"first_name":"Matthias","full_name":"Pukrop, Matthias","last_name":"Pukrop"},{"full_name":"Rozas, Elena","last_name":"Rozas","first_name":"Elena"},{"first_name":"Jan","full_name":"Sperling, Jan","id":"75127","orcid":"0000-0002-5844-3205","last_name":"Sperling"},{"orcid":"0000-0003-4042-4951","last_name":"Schumacher","id":"27271","full_name":"Schumacher, Stefan","first_name":"Stefan"},{"last_name":"Aßmann","full_name":"Aßmann, Marc","first_name":"Marc"}],"title":"Continuous-variable quantum optics and resource theory for ultrafast semiconductor spectroscopy [Invited]","doi":"10.1364/ome.497006","publication_identifier":{"issn":["2159-3930"]},"publication_status":"published","issue":"11","year":"2023","intvolume":"        13","citation":{"ama":"Lüders C, Barkhausen F, Pukrop M, et al.

Combining these characteristics with temporal control of SNSPDs broadens their applications as in active de-latching for higher dynamic range counting or temporal filtering for pump-probe spectroscopy or LiDAR. 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. We exploit gated operation to demonstrate a method to increase in the photon counting dynamic range by a factor 11.2, as well as temporal filtering of a strong pump in an emulated pump-probe experiment.</jats:p>"}],"status":"public","type":"journal_article","publication":"Optics Express"},{"date_updated":"2025-12-11T20:46:50Z","date_created":"2025-12-11T20:37:08Z","title":"Tunable vector beam decoder by inverse design for high-dimensional quantum key distribution with 3D polarized spatial modes","doi":"10.48550/ARXIV.2304.12296","year":"2023","citation":{"apa":"<i>Tunable vector beam decoder by inverse design for high-dimensional quantum key distribution with 3D polarized spatial modes</i>.

For this reason, a considerable amount of engineering effort has been taken in order to improve the quality of particle sources and system components. At the same time, data analysis and collection methods based on post-selection have been used to mitigate the effect of particle losses. This has allowed for investigating experimentally multi-particle evolutions where the observer lacks knowledge about the system's intermediate propagation states. Nonetheless, the fundamental question how losses affect the behaviour of the surviving subset of a multi-particle system has not been investigated so far. For this reason, here we study the impact of particle losses in a quantum walk of two photons reconstructing the output probability distributions for one photon conditioned on the loss of the other in a known mode and temporal step of our evolution network. We present the underlying theoretical scheme that we have devised in order to model controlled particle losses, we describe an experimental platform capable of implementing our theory in a time multiplexing encoding. In the end we show how localized particle losses change the output distributions without altering their asymptotic spreading properties. Finally we devise a quantum civilization problem, a two walker generalisation of single particle recurrence processes.","lang":"eng"}],"language":[{"iso":"eng"}],"issue":"3","year":"2023","date_created":"2023-03-02T09:53:59Z","publisher":"IOP Publishing","title":"Dynamic conditioning of two particle discrete-time quantum walks","type":"journal_article","status":"public","user_id":"68236","department":[{"_id":"623"},{"_id":"15"},{"_id":"288"},{"_id":"169"}],"_id":"42648","article_number":"034005","article_type":"original","publication_status":"published","publication_identifier":{"issn":["0031-8949","1402-4896"]},"citation":{"bibtex":"@article{Pegoraro_Held_Barkhofen_Brecht_Silberhorn_2023, title={Dynamic conditioning of two particle discrete-time quantum walks}, volume={98}, DOI={<a href=\"https://doi.org/10.1088/1402-4896/acbcaa\">10.1088/1402-4896/acbcaa</a>}, number={3034005}, journal={Physica Scripta}, publisher={IOP Publishing}, author={Pegoraro, Federico and Held, Philip and Barkhofen, Sonja and Brecht, Benjamin and Silberhorn, Christine}, year={2023} }","mla":"Pegoraro, Federico, et al. “Dynamic Conditioning of Two Particle Discrete-Time Quantum Walks.” <i>Physica Scripta</i>, vol. 98, no. 3, 034005, IOP Publishing, 2023, doi:<a href=\"https://doi.org/10.1088/1402-4896/acbcaa\">10.1088/1402-4896/acbcaa</a>.","short":"F.
