Such interferometers have been successfully realized in bulk and fiber-based configurations. However, rapidly developing integrated technologies provide higher efficiencies, smaller footprints, and pave the way to quantum-enhanced on-chip interferometry. In this work, we theoretically realised an integrated architecture of the multimode SU(1,1) interferometer which can be applied to various integrated platforms. The presented interferometer includes a polarization converter between two photon sources and utilizes a continuous-wave (CW) pump. Based on the potassium titanyl phosphate (KTP) platform, we show that this configuration results in almost perfect destructive interference at the output and supersensitivity regions below the classical limit. In addition, we discuss the fundamental difference between single-mode and highly multimode SU(1,1) interferometers in the properties of phase sensitivity and its limits. Finally, we explore how to improve the phase sensitivity by filtering the output radiation and using different seeding states in different modes with various detection strategies.</jats:p>","lang":"eng"}],"publication":"Quantum","type":"journal_article","language":[{"iso":"eng"}],"article_number":"461","department":[{"_id":"15"},{"_id":"288"}],"user_id":"42777","_id":"26077","project":[{"name":"TRR 142 - C: TRR 142 - Project Area C","_id":"56"}],"citation":{"short":"A.

However, the mode structure of pulsed sources and the properties of the detection schemes often require the use of optical filters in order to combine both detection methods in a common experiment. This limits the efficiency and the overall achievable squeezing of the experiment. In our work, we use photon subtraction to implement the distillation of pulsed squeezed states originating from a genuinely spatially and temporally single-mode parametric down-conversion source in non-linear waveguides. Due to the distillation, we witness an improvement of 0.17 dB from an initial squeezing value of −1.648 ± 0.002 dB, while achieving a purity of 0.58, and confirm the non-Gaussianity of the distilled state via the higher-order cumulants. With this, we demonstrate the source’s suitability for scalable hybrid quantum network applications with pulsed quantum light.</jats:p>","lang":"eng"}]},{"project":[{"_id":"55","name":"TRR 142 - B: TRR 142 - Project Area B"}],"_id":"21025","user_id":"13244","department":[{"_id":"15"},{"_id":"230"},{"_id":"429"},{"_id":"288"}],"article_number":"32925-32935","language":[{"iso":"eng"}],"type":"journal_article","publication":"Optics Express","status":"public","date_updated":"2023-02-01T12:46:27Z","date_created":"2021-01-20T08:35:45Z","author":[{"first_name":"Christof","full_name":"Eigner, Christof","id":"13244","orcid":"https://orcid.org/0000-0002-5693-3083","last_name":"Eigner"},{"first_name":"Laura","id":"40300","full_name":"Padberg, Laura","last_name":"Padberg"},{"full_name":"Santandrea, Matteo","id":"55095","last_name":"Santandrea","orcid":"0000-0001-5718-358X","first_name":"Matteo"},{"first_name":"Harald","last_name":"Herrmann","id":"216","full_name":"Herrmann, Harald"},{"id":"27150","full_name":"Brecht, Benjamin","orcid":"0000-0003-4140-0556 ","last_name":"Brecht","first_name":"Benjamin"},{"first_name":"Christine","last_name":"Silberhorn","id":"26263","full_name":"Silberhorn, Christine"}],"volume":28,"title":"Spatially single mode photon pair source at 800 nm in periodically poled Rubidium exchanged KTP waveguides","doi":"10.1364/oe.399483","publication_status":"published","publication_identifier":{"issn":["1094-4087"]},"issue":"22","year":"2020","citation":{"bibtex":"@article{Eigner_Padberg_Santandrea_Herrmann_Brecht_Silberhorn_2020, title={Spatially single mode photon pair source at 800 nm in periodically poled Rubidium exchanged KTP waveguides}, volume={28}, DOI={<a href=\"https://doi.org/10.1364/oe.399483\">10.1364/oe.399483</a>}, number={2232925–32935}, journal={Optics Express}, author={Eigner, Christof and Padberg, Laura and Santandrea, Matteo and Herrmann, Harald and Brecht, Benjamin and Silberhorn, Christine}, year={2020} }","short":"C.

In this work, we use density-functional theory and Green's function methods to explore the microscopic structure and spectroscopic signatures of electron polarons in lithium niobate (LiNbO3). Total-energy calculations and the comparison of calculated electron paramagnetic resonance data with available measurements reveal the formation of bound \r\npolarons at Nb_Li antisite defects with a quasi-Jahn-Teller distorted, tilted configuration. The defect-formation energies further indicate that (bi)polarons may form not only at \r\nNb_Li antisites but also at structures where the antisite Nb atom moves into a neighboring empty oxygen octahedron. Based on these structure models, and on the calculated charge-transition levels and potential-energy barriers, we propose two mechanisms for the optical and thermal splitting of bipolarons, which provide a natural explanation for the reported two-path recombination of bipolarons. Optical-response calculations based on the Bethe-Salpeter equation, in combination with available experimental data and new measurements of the optical absorption spectrum, further corroborate the geometries proposed here for free and defect-bound (bi)polarons.","lang":"eng"}],"file":[{"relation":"main_file","access_level":"open_access","file_id":"19843","description":"Creative Commons Attribution 4.0 International Public License (CC BY 4.0)","title":"Free and defect-bound (bi)polarons in LiNbO3: Atomic structure and spectroscopic signatures from ab initio calculations","date_created":"2020-10-02T07:27:38Z","date_updated":"2020-10-02T07:37:24Z","content_type":"application/pdf","file_name":"PhysRevResearch.2.043002.pdf","file_size":1955183,"creator":"schindlm"}],"external_id":{"isi":["000604206300002"]},"ddc":["530"],"language":[{"iso":"eng"}],"quality_controlled":"1","issue":"4","year":"2020","publisher":"American Physical Society","date_created":"2020-09-09T09:35:21Z","title":"Free and defect-bound (bi)polarons in LiNbO3: Atomic structure and spectroscopic signatures from ab initio calculations"}]
