We used XRF analysis to determine the elemental composition of the crystals. The Neumann–Kopp rule provided essential data for the end members lithium niobate (LN) and lithium tantalate (LT). The heats of fusion of the end members, given by DTA measurements, are 103 kJ/mol at 1531 K for LN and 289 kJ/mol at 1913 K for LT. These values were used as input parameters to generate the data. This data served as the basis for calculating a phase diagram for LN-LT solid solutions. Finally, based on the experimental data and a thermodynamic solution model, the Calphad Factsage module optimized the phase diagram. We also generated thermodynamic parameters for Gibbs’ excess energy of the solid solution. A plot of the segregation coefficient as a function of Ta concentration was derived from the phase diagram.","lang":"eng"}],"publication":"Journal of Materials Science","doi":"10.1007/s10853-024-09932-7","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1007/s10853-024-09932-7"}],"language":[{"iso":"eng"}],"date_updated":"2024-07-05T06:49:25Z","publication_status":"published","year":"2024","title":"Evaluation and thermodynamic optimization of phase diagram of lithium niobate tantalate solid solutions","publication_identifier":{"issn":["0022-2461","1573-4803"]},"author":[{"last_name":"Bashir","first_name":"Umar","full_name":"Bashir, Umar"},{"last_name":"Klimm","first_name":"Detlef","full_name":"Klimm, Detlef"},{"id":"22501","full_name":"Rüsing, Michael","first_name":"Michael","orcid":"0000-0003-4682-4577","last_name":"Rüsing"},{"last_name":"Bickermann","first_name":"Matthias","full_name":"Bickermann, Matthias"},{"last_name":"Ganschow","first_name":"Steffen","full_name":"Ganschow, Steffen"}],"oa":"1","quality_controlled":"1","citation":{"ieee":"U.

We find that the rising edge as well as the amplitude of the electrical signal have the most dependence on photon number. Accurately measuring the rising edge while simultaneously measuring the voltage of the pulse amplitude maximizes the photon-number resolution of SNSPDs. Using an optimal basis of principal components, we show unambiguous discrimination between one- and two-photon events, as well as partial resolution up to five photons. This expands the use case of SNSPDs to photon-counting experiments, without the need of detector multiplexing architectures.</jats:p>\r\n          <jats:sec>\r\n            <jats:title/>\r\n            <jats:supplementary-material>\r\n              <jats:permissions>\r\n                <jats:copyright-statement>Published by the American Physical Society</jats:copyright-statement>\r\n                <jats:copyright-year>2024</jats:copyright-year>\r\n              </jats:permissions>\r\n            </jats:supplementary-material>\r\n          </jats:sec>"}],"publication":"Physical Review Applied","issue":"1","doi":"10.1103/physrevapplied.22.014024","language":[{"iso":"eng"}],"article_number":"014024","main_file_link":[{"open_access":"1"}],"intvolume":"        22","publication_status":"published","date_updated":"2024-07-11T09:36:00Z","author":[{"full_name":"Schapeler, Timon","first_name":"Timon","orcid":"0000-0001-7652-1716","last_name":"Schapeler","id":"55629"},{"first_name":"Niklas","last_name":"Lamberty","full_name":"Lamberty, Niklas"},{"id":"83846","full_name":"Hummel, Thomas","first_name":"Thomas","orcid":"0000-0001-8627-2119","last_name":"Hummel"},{"id":"63579","last_name":"Schlue","first_name":"Fabian","full_name":"Schlue, Fabian"},{"id":"42777","full_name":"Stefszky, Michael","last_name":"Stefszky","first_name":"Michael"},{"first_name":"Benjamin","last_name":"Brecht","orcid":"0000-0003-4140-0556 ","full_name":"Brecht, Benjamin","id":"27150"},{"id":"26263","full_name":"Silberhorn, Christine","first_name":"Christine","last_name":"Silberhorn"},{"id":"49683","full_name":"Bartley, Tim","first_name":"Tim","last_name":"Bartley"}],"publication_identifier":{"issn":["2331-7019"]},"title":"Electrical trace analysis of superconducting nanowire photon-number-resolving detectors","year":"2024","oa":"1","project":[{"call_identifier":"ERC","name":"QuESADILLA: ERC-Grant: QuESADILLA: Quantum Engineering Superconducting Array Detectors in Low-Light Applications","_id":"239","grant_number":"101042399"},{"name":"PhoQuant--QCTest: PhoQuant: Photonische Quantencomputer -  Quantencomputing Testplattform","_id":"191","grant_number":"13N16103"}],"citation":{"apa":"Schapeler, T., Lamberty, N., Hummel, T., Schlue, F., Stefszky, M., Brecht, B., Silberhorn, C., &#38; Bartley, T.

However, BCARS encounters spectral distortion due to a setup-dependent non-resonant background (NRB). This study assesses BCARS reproducibility through a round robin experiment using two distinct BCARS setups and crystalline materials with varying structural complexity, including diamond, 6H-SiC, KDP, and KTP. The analysis compares setup-specific NRB correction procedures, detected and NRB-removed spectra, and mode assignment. We determine the influence of BCARS setup parameters like pump wavelength, pulse width, and detection geometry and provide a practical guide for optimizing BCARS setups for solid-state applications."}],"publication":"Applied Optics","issue":"1"},{"_id":"60023","language":[{"iso":"eng"}],"user_id":"30525","title":"Dielectric metasurface for wave-vector variant and circular polarization dependent transmission","status":"public","year":"2024","conference":{"end_date":"2024-07-19","name":"META 2024 - The 14th International Conference on Metamaterials, Photonic Crystals and Plasmonics","start_date":"2024-07-16","location":"Toyama, Japan"},"author":[{"full_name":"Wetter, Helene","last_name":"Wetter","first_name":"Helene"},{"first_name":"Wenlong","last_name":"Gao","full_name":"Gao, Wenlong"},{"full_name":"Rehberg, Falk","first_name":"Falk","last_name":"Rehberg"},{"id":"69187","full_name":"Wingenbach, Jan","first_name":"Jan","last_name":"Wingenbach"},{"full_name":"Schumacher, Stefan","first_name":"Stefan","orcid":"0000-0003-4042-4951","last_name":"Schumacher","id":"27271"},{"id":"30525","full_name":"Zentgraf, Thomas","first_name":"Thomas","last_name":"Zentgraf","orcid":"0000-0002-8662-1101"}],"publication_identifier":{"issn":["2429-1390"]},"date_updated":"2025-05-23T06:34:16Z","date_created":"2025-05-23T06:30:36Z","type":"conference","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"publication":"Proceedings of The 14th International Conference on Metamaterials, Photonic Crystals and Plasmonics","citation":{"ama":"Wetter H, Gao W, Rehberg F, Wingenbach J, Schumacher S, Zentgraf T.

We explicitly demonstrate the theoretical generation of linear cluster states with substantial numbers of entangled photonic qubits in full microscopic numerical simulations. The underlying scheme is based on the manipulation of ground state coherences through precise optical driving. One important finding is that the most easily accessible quality metrics, the achievable rotation fidelities, fall short in assessing the actual quantum correlations of the emitted photons in the face of losses. To address this, we explicitly calculate stabilizer generator expectation values as a superior gauge for the quantum properties of the generated many-photon state. With widespread applicability in other emitter and excitation–emission schemes also, our work lays the conceptual foundations for an in-depth practical analysis of time-bin entanglement based on full numerical simulations with predictive capabilities for realistic systems and setups, including losses and imperfections. The specific results shown in the present work illustrate that with controlled minimization of losses and realistic system parameters for quantum-dot type systems, useful linear cluster states of significant lengths can be generated in the calculations, discussing the possibility of scalability for quantum information processing endeavors.</jats:p>"}],"issue":"3","publication":"APL Quantum","doi":"10.1063/5.0214197","language":[{"iso":"eng"}],"article_number":"036110","intvolume":"         1","publication_status":"published","date_updated":"2025-09-12T11:11:32Z","author":[{"full_name":"Bauch, David","last_name":"Bauch","first_name":"David"},{"full_name":"Köcher, Nikolas","last_name":"Köcher","first_name":"Nikolas","id":"79191"},{"full_name":"Heinisch, Nils","first_name":"Nils","last_name":"Heinisch","orcid":"0009-0006-0984-2097","id":"90283"},{"id":"27271","full_name":"Schumacher, Stefan","last_name":"Schumacher","first_name":"Stefan","orcid":"0000-0003-4042-4951"}],"publication_identifier":{"issn":["2835-0103"]},"title":"Time-bin entanglement in the deterministic generation of linear photonic cluster states","year":"2024"},{"publication_status":"published","date_updated":"2025-12-01T08:49:46Z","title":"Orchestrating time and color: a programmable source of high-dimensional entanglement","status":"public","year":"2024","publication_identifier":{"issn":["2837-6714"]},"author":[{"full_name":"Serino, Laura","last_name":"Serino","first_name":"Laura","id":"88242"},{"last_name":"Ridder","first_name":"Werner","full_name":"Ridder, Werner","id":"63574"},{"first_name":"Abhinandan","last_name":"Bhattacharjee","full_name":"Bhattacharjee, Abhinandan","id":"95902"},{"id":"51223","full_name":"Gil López, Jano","last_name":"Gil López","first_name":"Jano"},{"id":"27150","full_name":"Brecht, Benjamin","first_name":"Benjamin","orcid":"0000-0003-4140-0556 ","last_name":"Brecht"},{"first_name":"Christine","last_name":"Silberhorn","full_name":"Silberhorn, Christine","id":"26263"}],"user_id":"63574","doi":"10.1364/opticaq.532334","_id":"56267","publisher":"Optica Publishing Group","language":[{"iso":"eng"}],"project":[{"name":"QuICHE: Quanteninformation und Quantenkommunikation mit hochdimensionaler Informationskodierung (QuICHE)","_id":"211"}],"publication":"Optica Quantum","citation":{"mla":"Serino, Laura, et al. “Orchestrating Time and Color: A Programmable Source of High-Dimensional Entanglement.” <i>Optica Quantum</i>, Optica Publishing Group, 2024, doi:<a href=\"https://doi.org/10.1364/opticaq.532334\">10.1364/opticaq.532334</a>.","ama":"Serino L, Ridder W, Bhattacharjee A, Gil López J, Brecht B, Silberhorn C.

The leading candidate to generate such pairs is based on spontaneous parametric down-conversion (SPDC) in non-linear crystals. However, its pair extraction efficiency is limited to 0.1% when operating at near-unity fidelity due to multiphoton emission at high brightness. Quantum dots in photonic nanostructures can in principle overcome this limit, but the devices with high entanglement fidelity (99%) have low pair extraction efficiency (0.01%). Here, we show a measured peak entanglement fidelity of 97.5% ± 0.8% and pair extraction efficiency of 0.65% from an InAsP quantum dot in an InP photonic nanowire waveguide. We show that the generated oscillating two-photon Bell state can establish a secure key for peer-to-peer QKD. Using our time-resolved QKD scheme alleviates the need to remove the quantum dot energy splitting of the intermediate exciton states in the biexciton-exciton cascade.</jats:p>"}]},{"doi":"10.1117/12.3009736","user_id":"48188","editor":[{"last_name":"Hemmer","first_name":"Philip R.","full_name":"Hemmer, Philip R."},{"full_name":"Migdall, Alan L.","first_name":"Alan L.","last_name":"Migdall"}],"language":[{"iso":"eng"}],"_id":"62852","publisher":"SPIE","date_updated":"2025-12-04T12:24:04Z","publication_status":"published","status":"public","year":"2024","title":"Integrating superconducting single-photon detectors into active photonic circuits","author":[{"full_name":"Gyger, Samuel","first_name":"Samuel","last_name":"Gyger"},{"first_name":"Max","last_name":"Tao","full_name":"Tao, Max"},{"first_name":"Marco","last_name":"Colangelo","full_name":"Colangelo, Marco"},{"last_name":"Christen","first_name":"Ian","full_name":"Christen, Ian"},{"last_name":"Larocque","first_name":"Hugo","full_name":"Larocque, Hugo"},{"full_name":"Zichi, Julian","last_name":"Zichi","first_name":"Julian"},{"full_name":"Schweickert, Lucas","last_name":"Schweickert","first_name":"Lucas"},{"last_name":"Elshaari","first_name":"Ali","full_name":"Elshaari, Ali"},{"last_name":"Steinhauer","first_name":"Stephan","full_name":"Steinhauer, Stephan"},{"first_name":"Saimon","last_name":"Covre da Silva","full_name":"Covre da Silva, Saimon"},{"full_name":"Rastelli, Armando","last_name":"Rastelli","first_name":"Armando"},{"first_name":"Hamed","last_name":"Sattari","full_name":"Sattari, Hamed"},{"first_name":"Gregory","last_name":"Chong","full_name":"Chong, Gregory"},{"last_name":"Pétremand","first_name":"Yves","full_name":"Pétremand, Yves"},{"last_name":"Prieto","first_name":"Ivan","full_name":"Prieto, Ivan"},{"full_name":"Yu, Yang","first_name":"Yang","last_name":"Yu"},{"full_name":"Ghadimi, Amir","first_name":"Amir","last_name":"Ghadimi"},{"full_name":"Englund, Dirk","last_name":"Englund","first_name":"Dirk"},{"full_name":"Jöns, Klaus","last_name":"Jöns","first_name":"Klaus","id":"85353"},{"full_name":"Zwiller, Val","last_name":"Zwiller","first_name":"Val"},{"first_name":"Carlos","last_name":"Errando Herranz","full_name":"Errando Herranz, Carlos"}],"type":"conference","department":[{"_id":"623"}],"date_created":"2025-12-04T12:07:37Z","publication":"Quantum Computing, Communication, and Simulation IV","citation":{"mla":"Gyger, Samuel, et al. “Integrating Superconducting Single-Photon Detectors into Active Photonic Circuits.” <i>Quantum Computing, Communication, and Simulation IV</i>, edited by Philip R.

The underlying scheme is based on the manipulation of ground state coherences through precise optical driving. One important finding is that the most easily accessible quality metrics, the achievable rotation fidelities, fall short in assessing the actual quantum correlations of the emitted photons in the face of losses. To address this, we explicitly calculate stabilizer generator expectation values as a superior gauge for the quantum properties of the generated many-photon state. With widespread applicability in other emitter and excitation–emission schemes also, our work lays the conceptual foundations for an in-depth practical analysis of time-bin entanglement based on full numerical simulations with predictive capabilities for realistic systems and setups, including losses and imperfections.

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>","lang":"eng"}],"date_created":"2025-12-04T12:08:46Z","department":[{"_id":"623"},{"_id":"15"},{"_id":"429"},{"_id":"642"}],"type":"journal_article","author":[{"last_name":"Boos","first_name":"Katarina","full_name":"Boos, Katarina"},{"last_name":"Sbresny","first_name":"Friedrich","full_name":"Sbresny, Friedrich"},{"full_name":"Kim, Sang Kyu","last_name":"Kim","first_name":"Sang Kyu"},{"full_name":"Kremser, Malte","first_name":"Malte","last_name":"Kremser"},{"full_name":"Riedl, Hubert","last_name":"Riedl","first_name":"Hubert"},{"full_name":"Bopp, Frederik W.","first_name":"Frederik W.","last_name":"Bopp"},{"full_name":"Rauhaus, William","last_name":"Rauhaus","first_name":"William"},{"full_name":"Scaparra, Bianca","first_name":"Bianca","last_name":"Scaparra"},{"id":"85353","first_name":"Klaus","last_name":"Jöns","full_name":"Jöns, Klaus"},{"full_name":"Finley, Jonathan J.","last_name":"Finley","first_name":"Jonathan J."},{"full_name":"Müller, Kai","last_name":"Müller","first_name":"Kai"},{"first_name":"Lukas","last_name":"Hanschke","full_name":"Hanschke, Lukas"}],"publication_identifier":{"issn":["2511-9044","2511-9044"]},"title":"Coherent Swing‐Up Excitation for Semiconductor Quantum Dots","year":"2024","intvolume":"         7","date_updated":"2025-12-11T13:00:06Z","publication_status":"published","language":[{"iso":"eng"}],"article_number":"2300359","doi":"10.1002/qute.202300359","citation":{"mla":"Boos, Katarina, et al. “Coherent Swing‐Up Excitation for Semiconductor Quantum Dots.” <i>Advanced Quantum Technologies</i>, vol. 7, no. 4, 2300359, Wiley, 2024, doi:<a href=\"https://doi.org/10.1002/qute.202300359\">10.1002/qute.202300359</a>.","apa":"Boos, K., Sbresny, F., Kim, S.

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"}]}]
