From this, we formulate a quantitative physical model of the multi-photon detector response that combines the local detection mechanism and local fluctuations (hotspot formation and intrinsic jitter) with the thermoelectric dynamics of resistive domains. Our model provides an excellent description of the arrival-time histogram of a commercial SNSPD across several orders of magnitude, both in arrival-time probability and across mean photon number. This is achieved with just three fitting parameters: the scaling of the mean arrival time of voltage response pulses, as well as the Gaussian and exponential jitter components. Our findings have important implications for photon-number-resolving detector design, as well as applications requiring low jitter, such as light detection and ranging (LIDAR)."}],"date_created":"2025-09-01T11:12:19Z","department":[{"_id":"623"},{"_id":"15"}],"type":"journal_article","keyword":["Jitter","PNR","SNSPD"],"author":[{"full_name":"Sidorova, Mariia","first_name":"Mariia","last_name":"Sidorova"},{"first_name":"Timon","orcid":"0000-0001-7652-1716","last_name":"Schapeler","full_name":"Schapeler, Timon","id":"55629"},{"last_name":"Semenov","first_name":"Alexej D.","full_name":"Semenov, Alexej D."},{"id":"63579","full_name":"Schlue, Fabian","last_name":"Schlue","first_name":"Fabian"},{"id":"42777","full_name":"Stefszky, Michael","first_name":"Michael","last_name":"Stefszky"},{"id":"27150","first_name":"Benjamin","last_name":"Brecht","orcid":"0000-0003-4140-0556 ","full_name":"Brecht, Benjamin"},{"id":"26263","full_name":"Silberhorn, Christine","last_name":"Silberhorn","first_name":"Christine"},{"full_name":"Bartley, Tim","last_name":"Bartley","first_name":"Tim","id":"49683"}],"publication_identifier":{"issn":["2378-0967"]},"year":"2025","title":"Jitter in photon-number-resolved detection by superconducting nanowires","intvolume":" 10","article_type":"original","date_updated":"2025-09-02T10:47:08Z","publication_status":"published","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1"}],"article_number":"086113","doi":"10.1063/5.0273752"},{"language":[{"iso":"eng"}],"article_number":"074402","main_file_link":[{"open_access":"1","url":"https://link.aps.org/doi/10.1103/5wz1-bjyr"}],"doi":"10.1103/5wz1-bjyr","publication_identifier":{"issn":["2475-9953"]},"author":[{"full_name":"Bocchini, Adriana","first_name":"Adriana","last_name":"Bocchini","orcid":"0000-0002-2134-3075","id":"58349"},{"id":"22501","last_name":"Rüsing","first_name":"Michael","orcid":"0000-0003-4682-4577","full_name":"Rüsing, Michael"},{"id":"61375","first_name":"Laura","last_name":"Bollmers","full_name":"Bollmers, Laura"},{"id":"44373","full_name":"Lengeling, Sebastian","last_name":"Lengeling","first_name":"Sebastian"},{"full_name":"Mues, Philipp","orcid":"0000-0003-0643-7636","first_name":"Philipp","last_name":"Mues","id":"49772"},{"last_name":"Padberg","first_name":"Laura","full_name":"Padberg, Laura","id":"40300"},{"full_name":"Gerstmann, Uwe","orcid":"0000-0002-4476-223X","first_name":"Uwe","last_name":"Gerstmann","id":"171"},{"first_name":"Christine","last_name":"Silberhorn","full_name":"Silberhorn, Christine","id":"26263"},{"full_name":"Eigner, Christof","first_name":"Christof","last_name":"Eigner","orcid":"https://orcid.org/0000-0002-5693-3083","id":"13244"},{"full_name":"Schmidt, Wolf Gero","last_name":"Schmidt","first_name":"Wolf Gero","orcid":"0000-0002-2717-5076","id":"468"}],"year":"2025","title":"Mg dopants in lithium niobate: Defect models and impact on domain inversion","intvolume":" 9","publication_status":"published","date_updated":"2026-03-17T17:50:06Z","date_created":"2025-07-09T09:13:24Z","file":[{"creator":"adrianab","date_created":"2025-07-09T09:18:45Z","file_name":"Mg_dopants_LN_PRM.pdf","file_size":4175120,"access_level":"open_access","relation":"main_file","date_updated":"2025-07-10T06:43:34Z","file_id":"60567","content_type":"application/pdf"}],"department":[{"_id":"15"},{"_id":"623"},{"_id":"295"},{"_id":"790"},{"_id":"288"},{"_id":"230"},{"_id":"429"},{"_id":"35"},{"_id":"170"},{"_id":"169"},{"_id":"27"}],"type":"journal_article","issue":"7","publication":"Physical Review Materials","publisher":"American Physical Society (APS)","_id":"60566","volume":9,"user_id":"22501","ddc":["530"],"status":"public","has_accepted_license":"1","oa":"1","citation":{"apa":"Bocchini, A., Rüsing, M., Bollmers, L., Lengeling, S., Mues, P., Padberg, L., Gerstmann, U., Silberhorn, C., Eigner, C., & Schmidt, W.

We show that such a measurement enables one to infer directly the degree of global coherence of that beam, which is linked by a simple relation to the number of modes characterizing the entanglement between the two generated beams. We illustrate the proposed method by an example of photon pairs generated in a periodically poled potassium titanyl phosphate (KTP) crystal with a symmetric group velocity matching for various durations of the pump pulse, resulting in different numbers of modes. Our theoretical model also shows that the magnified double-heralded autocorrelation function of one beam exhibits a local maximum around zero delay time, corresponding to photon bunching at a short time scale.","lang":"eng"}],"publication":"Physical Review A","issue":"2","department":[{"_id":"623"},{"_id":"15"},{"_id":"288"}],"type":"journal_article","date_created":"2026-01-26T14:28:22Z"},{"citation":{"apa":"Kress, C., Schwabe, T., Mihaylov, M.

Our first main result shows\r\nthat, surprisingly, QSAT on qubits can remain $\\mathsf{QMA}_1$-hard, in that\r\n$(2,5)$-QSAT is $\\mathsf{QMA}_1$-complete. In contrast, $2$-SAT on qubits is\r\nwell-known to be poly-time solvable [Bravyi, 2006]. Our second main result\r\nproves that $(3,d)$-QSAT on the 1D line with $d\\in O(1)$ is also\r\n$\\mathsf{QMA}_1$-hard. Finally, we initiate the study of 1D $(2,d)$-QSAT by\r\ngiving a frustration-free 1D Hamiltonian with a unique, entangled ground state.\r\n Our first result uses a direct embedding, combining a novel clock\r\nconstruction with the 2D circuit-to-Hamiltonian construction of [Gosset, Nagaj,\r\n2013]. Of note is a new simplified and analytic proof for the latter (as\r\nopposed to a partially numeric proof in [GN13]). This exploits Unitary Labelled\r\nGraphs [Bausch, Cubitt, Ozols, 2017] together with a new \"Nullspace Connection\r\nLemma\", allowing us to break low energy analyses into small patches of\r\nprojectors, and to improve the soundness analysis of [GN13] from\r\n$\\Omega(1/T^6)$ to $\\Omega(1/T^2)$, for $T$ the number of gates. Our second\r\nresult goes via black-box reduction: Given an arbitrary 1D Hamiltonian $H$ on\r\n$d'$-dimensional qudits, we show how to embed it into an effective null-space\r\nof a 1D $(3,d)$-QSAT instance, for $d\\in O(1)$.

Current-voltage (I-U) characteristics, recorded at variable temperatures from LiNbO3 (LNO) DWs, are clearly able to differentiate between these two contributions. Practically, they allow us to directly quantify the physical parameters relevant to the two mechanisms (a) and (b) mentioned above. These are, for example, the resistance of the DW, the saturation current, the ideality factor, and the Schottky barrier height of the electrode-DW junction. Furthermore, the activation energies needed to initiate the thermally activated electronic transport along the DWs can be extracted. In addition, we show that electronic transport along LNO DWs can be elegantly viewed and interpreted in an adapted semiconductor picture based on a double-diode, double-resistor equivalent-circuit model, the R2D2 model. Finally, our R2D2 model was checked for its universality by successfully fitting the I-U curves of not only z-cut LNO bulk DWs, but equally of z-cut thin-film LNO DWs, and of x-cut thin-film DWs as reported in literature.","lang":"eng"}],"publication":"Physical Review Applied","issue":"2"},{"date_updated":"2024-02-13T13:09:51Z","publication_status":"published","publication_identifier":{"issn":["1094-4087"]},"author":[{"first_name":"Jonas","last_name":"Babai-Hemati","full_name":"Babai-Hemati, Jonas"},{"id":"71245","first_name":"Felix","last_name":"vom Bruch","full_name":"vom Bruch, Felix"},{"id":"216","first_name":"Harald","last_name":"Herrmann","full_name":"Herrmann, Harald"},{"first_name":"Christine","last_name":"Silberhorn","full_name":"Silberhorn, Christine","id":"26263"}],"status":"public","year":"2024","title":"Tailored second harmonic generation inTi-diffused PPLN waveguides usingmicro-heaters","doi":"10.1364/oe.510319","user_id":"216","_id":"51339","publisher":"Optica Publishing Group","language":[{"iso":"eng"}],"project":[{"_id":"266","grant_number":"PROFILNRW-2020-067","name":"PhoQC: PhoQC: Photonisches Quantencomputing"}],"citation":{"mla":"Babai-Hemati, Jonas, et al. “Tailored Second Harmonic Generation InTi-Diffused PPLN Waveguides Usingmicro-Heaters.” Optics Express, Optica Publishing Group, 2024, doi:10.1364/oe.510319.","bibtex":"@article{Babai-Hemati_vom Bruch_Herrmann_Silberhorn_2024, title={Tailored second harmonic generation inTi-diffused PPLN waveguides usingmicro-heaters}, DOI={10.1364/oe.510319}, journal={Optics Express}, publisher={Optica Publishing Group}, author={Babai-Hemati, Jonas and vom Bruch, Felix and Herrmann, Harald and Silberhorn, Christine}, year={2024} }","ama":"Babai-Hemati J, vom Bruch F, Herrmann H, Silberhorn C.

Furthermore, it provides fundamental insight into the effects of dispersion on the biphoton state. Here, we show that a characteristic dependence of the width of the temporal interferogram can be exploited to obtain insights into the amount of second-order dispersion inside the interferometer and to retrieve actual and Fourier-limited ultrashort biphoton correlation times of around 100 fs. In the presented scheme, we simultaneously measure spectral and temporal interferograms at the output of an SU(1,1) interferometer based on an integrated broadband parametric down conversion source in a Ti:LiNbO3 waveguide.","lang":"eng"}],"issue":"2","publication":"PRX Quantum","type":"journal_article","department":[{"_id":"288"},{"_id":"623"}],"date_created":"2024-06-01T12:48:51Z","status":"public","user_id":"88149","volume":5,"_id":"54544","publisher":"American Physical Society (APS)","project":[{"grant_number":"13N15065","_id":"207","name":"MiLiQuant: Miniaturisierte Lichtquellen für den industriellen Einsatz in Quantensensoren und Quanten-Imaging-Systemen (MiLiQuant) - Teilvorhaben: Technologie und Theorie für MIR Quanten-Imaging Systeme"},{"name":"MIRAQLS: MIRAQLS: Mid-infrared Quantum Technology for Sensing","grant_number":"101070700","_id":"571"},{"name":"E2TPA: Exploiting Entangled Two-Photon Absorption","_id":"190"}],"citation":{"mla":"Roeder, Franz, et al. “Measurement of Ultrashort Biphoton Correlation Times with an Integrated Two-Color Broadband SU(1,1)-Interferometer.” PRX Quantum, vol. 5, no. 2, 020350, American Physical Society (APS), 2024, doi:10.1103/prxquantum.5.020350.","ama":"Roeder F, Pollmann R, Stefszky M, et al.
