In this work, we investigate the impact of the optical pulse shape and duration on the accuracy of this method. We find that Gaussian temporal pulse shapes yield cleaner arrival-time histograms and, thus, more accurate PNR, compared to bandpass-filtered pulses of equal bandwidth. For low system jitter and an optical pulse duration comparable to the other jitter contributions, photon numbers can be discriminated in our system with a commercial SNSPD. At 60 ps optical pulse duration, photon-number discrimination is significantly reduced. Furthermore, we highlight the importance of using the correct arrival-time histogram model when analyzing photon-number assignment. Using exponentially modified Gaussian distributions, instead of the commonly used Gaussian distributions, we can more accurately determine photon-number misidentification probabilities. Finally, we reconstruct the positive operator-valued measures of the detector, revealing sharp features that indicate the intrinsic PNR capabilities.</jats:p>"}],"issue":"1","publication":"APL Quantum","doi":"10.1063/5.0304127","main_file_link":[{"open_access":"1"}],"article_number":"016102","language":[{"iso":"eng"}],"date_updated":"2026-03-25T08:00:27Z","publication_status":"published","intvolume":"         3","title":"Practical considerations for assignment of photon numbers with SNSPDs","year":"2026","author":[{"id":"55629","full_name":"Schapeler, Timon","last_name":"Schapeler","first_name":"Timon","orcid":"0000-0001-7652-1716"},{"full_name":"Mischke, Isabell","first_name":"Isabell","last_name":"Mischke"},{"id":"63579","first_name":"Fabian","last_name":"Schlue","full_name":"Schlue, Fabian"},{"id":"42777","first_name":"Michael","last_name":"Stefszky","full_name":"Stefszky, Michael"},{"last_name":"Brecht","first_name":"Benjamin","orcid":"0000-0003-4140-0556 ","full_name":"Brecht, Benjamin","id":"27150"},{"full_name":"Silberhorn, Christine","first_name":"Christine","last_name":"Silberhorn","id":"26263"},{"id":"49683","first_name":"Tim","last_name":"Bartley","full_name":"Bartley, Tim"}],"publication_identifier":{"issn":["2835-0103"]},"oa":"1","project":[{"name":"PhoQuant: Photonische Quantencomputer -  Quantencomputing Testplattform","_id":"191"},{"_id":"239","name":"ERC-Grant: QuESADILLA: Quantum Engineering Superconducting Array Detectors in Low-Light Applications"}],"citation":{"apa":"Schapeler, T., Mischke, I., Schlue, F., Stefszky, M., Brecht, B., Silberhorn, C., &#38; Bartley, T.

Recently, it has been experimentally demonstrated that photonic platforms based on Gaussian boson sampling (GBS) are capable of performing these simulations. However, whether an actual GBS approach is required depends on the molecule under investigation. To develop a better understanding on the requirements for simulating vibronic spectra, we explore connections between theoretical approximations in physical chemistry and their photonic counterparts. Mapping these approximations into photonics, we show that for certain molecules the GBS approach is unnecessary. We place special emphasis on the linear coupling approximation, which in photonics corresponds to sampling from multiple coherent states. By implementing this approach in experiments, we demonstrate improved similarities over previously reported GBS results for formic acid and identify the particular attributes that a molecule must exhibit for this, and other approximations, to be valid. These results highlight the importance in forming deeper connections between traditional methods and photonic approaches."}],"related_material":{"link":[{"relation":"research_data","url":"https://doi.org/10.5281/zenodo.18969354"}]},"issue":"1","publication":"npj Quantum Information","doi":"10.1038/s41534-026-01250-x","main_file_link":[{"url":"https://www.nature.com/articles/s41534-026-01250-x.pdf","open_access":"1"}],"article_number":"89","language":[{"iso":"eng"}],"date_updated":"2026-06-12T08:28:02Z","publication_status":"published","intvolume":"        12","article_type":"original","title":"Bridging chemistry and Gaussian boson sampling: a photonic hierarchy of approximations for molecular vibronic spectra","year":"2026","author":[{"full_name":"Eickmann, Jan-Lucas","first_name":"Jan-Lucas","orcid":"0009-0008-6524-7684","last_name":"Eickmann","id":"73665"},{"first_name":"Kai-Hong","last_name":"Luo","orcid":"0000-0003-1008-4976","full_name":"Luo, Kai-Hong","id":"36389"},{"last_name":"Roiz","first_name":"Mikhail","full_name":"Roiz, Mikhail","id":"114114"},{"full_name":"Lammers, Jonas","first_name":"Jonas","last_name":"Lammers"},{"last_name":"Atzeni","first_name":"Simone","full_name":"Atzeni, Simone","id":"98338"},{"full_name":"Pandey, Cheeranjiv","first_name":"Cheeranjiv","last_name":"Pandey"},{"last_name":"Lütkewitte","first_name":"Florian","full_name":"Lütkewitte, Florian"},{"last_name":"Shirazi","first_name":"Reza G.","full_name":"Shirazi, Reza G."},{"full_name":"Schlue, Fabian","first_name":"Fabian","last_name":"Schlue","id":"63579"},{"full_name":"Brecht, Benjamin","orcid":"0000-0003-4140-0556 ","first_name":"Benjamin","last_name":"Brecht","id":"27150"},{"full_name":"Rybkin, Vladimir V.","first_name":"Vladimir V.","last_name":"Rybkin"},{"full_name":"Stefszky, Michael","first_name":"Michael","last_name":"Stefszky","id":"42777"},{"full_name":"Silberhorn, Christine","last_name":"Silberhorn","first_name":"Christine","id":"26263"}],"publication_identifier":{"issn":["2056-6387"]},"oa":"1","project":[{"name":"PhoQuant: Photonische Quantencomputer -  Quantencomputing Testplattform","_id":"191"}],"citation":{"mla":"Eickmann, Jan-Lucas, et al. “Bridging Chemistry and Gaussian Boson Sampling: A Photonic Hierarchy of Approximations for Molecular Vibronic Spectra.” <i>Npj Quantum Information</i>, vol. 12, no. 1, 89, Springer Science and Business Media LLC, 2026, doi:<a href=\"https://doi.org/10.1038/s41534-026-01250-x\">10.1038/s41534-026-01250-x</a>.","ama":"Eickmann J-L, Luo K-H, Roiz M, et al.

These lattice are crucial for lattice-based cryptography. Our construction yields GKP codes with distance $\\sqrt{n/πe}$. This compares favorably with the NTRU-based construction by Conrad et al. that achieves distance $Ω(\\sqrt{n/q}),$ with $n\\le q^2/0.28$. Unlike their codes, our codes do not have secret keys that can be used to speed-up the decoding. However, we present a simple decoding algorithm that, for many parameter choices, experimentally yields decoding results similar to the ones for NTRU-based codes. Using the R-SIS and M-SIS construction, our simple decoding algorithm runs in nearly linear time.

They are recommended for long-term use cases like e.g. firmware signing. However, stateful signature schemes require to properly manage a so-called state. In stateful signature schemes like LMS and XMSS, signing keys consist of a set of keys of a one-time signature scheme and it has to be guaranteed that each one-time key is used only once. This is done by updating a state in each signature computation, basically recording which one-time keys have already been used. While this is straightforward in centralized systems, in distributed systems like secure enclaves consisting of e.g. multiple hardware security modules (HSMs) with limited communication keeping a distributed state that at any point in time is consistent among all parties involved presents a challenge. This challenge is not addressed by the current standardization processes. \r\nIn this paper we present a security model for the distributed key management of post-quantum secure stateful signatures like XMSS and LMS. We also present a simple, efficient, and easy to implement protocol proven secure in this security model, i.e. the protocol guarantees at any point in time a consistent state among the parties in a distributed system, like a distributed security enclave. The security model is defined in the universal composabilty (UC) framework by Ran Canetti by providing an ideal functionality for the distributed key management for stateful signatures. Hence our protocol remains secure even if arbitrarily composed with other instances of the same or other protocols, a necessity for the security of distributed key management protocols. Our main application are security enclaves consisting of HSMs, but the model and the protocol can easily be adapted to other scenarios of distributed key management of stateful signature schemes.","lang":"eng"}],"project":[{"_id":"191","name":"PhoQuant: Photonische Quantencomputer -  Quantencomputing Testplattform"}],"date_created":"2025-12-22T21:23:22Z","type":"preprint","keyword":["distributed state","hash-based signature","stateful hash-based signature","universal composability","secure enclave"],"department":[{"_id":"34"},{"_id":"64"}],"oa":"1","year":"2025","title":"Secure Distributed State Management for Stateful Signatures with a Practical and Universally Composable Protocol","status":"public","author":[{"full_name":"Blömer, Johannes","last_name":"Blömer","first_name":"Johannes","id":"23"},{"id":"41047","full_name":"Bröcher, Henrik","last_name":"Bröcher","first_name":"Henrik","orcid":"0009-0008-3938-5485"},{"last_name":"Krummel","first_name":"Volker","full_name":"Krummel, Volker"},{"full_name":"Porzenheim, Laurens Alexander","first_name":"Laurens Alexander","last_name":"Porzenheim","id":"47434"}],"publication_status":"submitted","date_updated":"2025-12-23T11:30:38Z","page":"22","main_file_link":[{"url":"https://eprint.iacr.org/2025/2278.pdf","open_access":"1"}],"language":[{"iso":"eng"}],"_id":"63403","user_id":"41047"},{"type":"conference","department":[{"_id":"15"},{"_id":"623"}],"date_created":"2025-07-11T09:18:09Z","project":[{"grant_number":"101042399","_id":"239","name":"QuESADILLA: ERC-Grant: QuESADILLA: Quantum Engineering Superconducting Array Detectors in Low-Light Applications","call_identifier":"ERC"},{"name":"PhoQuant--QCTest: PhoQuant: Photonische Quantencomputer -  Quantencomputing Testplattform","grant_number":"13N16103","_id":"191"}],"publication":"Advanced Photon Counting Techniques XIX","citation":{"mla":"Schapeler, Timon, et al. “Optimizing Photon-Number Resolution with Superconducting Nanowire Multi-Photon Detectors.” <i>Advanced Photon Counting Techniques XIX</i>, edited by Mark A.

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.

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).</jats:p>"}],"issue":"8","publication":"APL Photonics","type":"journal_article","keyword":["Jitter","PNR","SNSPD"],"department":[{"_id":"623"},{"_id":"15"}],"date_created":"2025-09-01T11:12:19Z","date_updated":"2025-09-02T10:47:08Z","publication_status":"published","intvolume":"        10","article_type":"original","title":"Jitter in photon-number-resolved detection by superconducting nanowires","year":"2025","publication_identifier":{"issn":["2378-0967"]},"author":[{"first_name":"Mariia","last_name":"Sidorova","full_name":"Sidorova, Mariia"},{"first_name":"Timon","last_name":"Schapeler","orcid":"0000-0001-7652-1716","full_name":"Schapeler, Timon","id":"55629"},{"full_name":"Semenov, Alexej D.","first_name":"Alexej D.","last_name":"Semenov"},{"id":"63579","full_name":"Schlue, Fabian","last_name":"Schlue","first_name":"Fabian"},{"id":"42777","first_name":"Michael","last_name":"Stefszky","full_name":"Stefszky, Michael"},{"id":"27150","first_name":"Benjamin","orcid":"0000-0003-4140-0556 ","last_name":"Brecht","full_name":"Brecht, Benjamin"},{"first_name":"Christine","last_name":"Silberhorn","full_name":"Silberhorn, Christine","id":"26263"},{"last_name":"Bartley","first_name":"Tim","full_name":"Bartley, Tim","id":"49683"}],"doi":"10.1063/5.0273752","main_file_link":[{"open_access":"1"}],"article_number":"086113","language":[{"iso":"eng"}],"project":[{"name":"PhoQuant: Photonische Quantencomputer -  Quantencomputing Testplattform","_id":"191"},{"_id":"239","name":"ERC-Grant: QuESADILLA: Quantum Engineering Superconducting Array Detectors in Low-Light Applications"}],"citation":{"ieee":"M.

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.

Developing tools to analyze these systems at the relevant scales, in a manner consistent with quantum mechanics, is therefore critical to benchmarking performance and characterizing their operation. While classical computational approaches cannot perform like-for-like computations of quantum systems beyond a certain scale, classical high-performance computing (HPC) may nevertheless be useful for precisely these characterization and certification tasks. By developing open-source customized algorithms using high-performance computing, we perform quantum tomography on a megascale quantum photonic detector covering a Hilbert space of 106. This requires finding 108 elements of the matrix corresponding to the positive operator valued measure (POVM), the quantum description of the detector, and is achieved in minutes of computation time. Moreover, by exploiting the structure of the problem, we achieve highly efficient parallel scaling, paving the way for quantum objects up to a system size of 1012 elements to be reconstructed using this method. In general, this shows that a consistent quantum mechanical description of quantum phenomena is applicable at everyday scales. More concretely, this enables the reconstruction of large-scale quantum sources, processes and detectors used in computation and sampling tasks, which may be necessary to prove their nonclassical character or quantum computational advantage."}],"publication":"Quantum Science and Technology","issue":"1","doi":"10.1088/2058-9565/ad8511","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1"}],"intvolume":"        10","date_updated":"2025-12-16T11:32:12Z","author":[{"full_name":"Schapeler, Timon","first_name":"Timon","last_name":"Schapeler","orcid":"0000-0001-7652-1716","id":"55629"},{"id":"75963","first_name":"Robert","last_name":"Schade","orcid":"0000-0002-6268-5397","full_name":"Schade, Robert"},{"full_name":"Lass, Michael","last_name":"Lass","first_name":"Michael","orcid":"0000-0002-5708-7632","id":"24135"},{"id":"16153","first_name":"Christian","last_name":"Plessl","orcid":"0000-0001-5728-9982","full_name":"Plessl, Christian"},{"id":"49683","full_name":"Bartley, Tim","first_name":"Tim","last_name":"Bartley"}],"year":"2024","title":"Scalable quantum detector tomography by high-performance computing","oa":"1","external_id":{"arxiv":["2404.02844"]},"project":[{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"_id":"239","name":"ERC-Grant: QuESADILLA: Quantum Engineering Superconducting Array Detectors in Low-Light Applications"},{"_id":"191","name":"PhoQuant: Photonische Quantencomputer -  Quantencomputing Testplattform"}],"citation":{"bibtex":"@article{Schapeler_Schade_Lass_Plessl_Bartley_2024, title={Scalable quantum detector tomography by high-performance computing}, volume={10}, DOI={<a href=\"https://doi.org/10.1088/2058-9565/ad8511\">10.1088/2058-9565/ad8511</a>}, number={1}, journal={Quantum Science and Technology}, publisher={IOP Publishing}, author={Schapeler, Timon and Schade, Robert and Lass, Michael and Plessl, Christian and Bartley, Tim}, year={2024} }","ama":"Schapeler T, Schade R, Lass M, Plessl C, Bartley T.
