Generating light that simultaneously carries high-order orbital angular momenta and exhibits quantum correlations is a challenging task. In this work, we present a theoretical approach to the generation of correlated Schmidt modes carrying OAM via parametric down-conversion (PDC) in cascaded nonlinear systems (nonlinear interferometers) pumped by Laguerre–Gaussian beams. We demonstrate how the number of generated modes and their population can be controlled by varying the pump parameters, the gain of the PDC process, and the distance between the crystals. We investigate the angular displacement measurement uncertainty of these interferometers and demonstrate that it can overcome the classical shot noise limit."}],"language":[{"iso":"eng"}]},{"title":"Simultaneous measurement of multimode squeezing through multimode phase-sensitive amplification","main_file_link":[{"open_access":"1","url":"https://opg.optica.org/opticaq/viewmedia.cfm?uri=opticaq-3-1-36&seq=0"}],"doi":"10.1364/opticaq.524682","publisher":"Optica Publishing Group","oa":"1","date_updated":"2026-02-10T22:44:44Z","date_created":"2026-01-26T15:57:13Z","author":[{"first_name":"Ismail","full_name":"Barakat, Ismail","last_name":"Barakat"},{"first_name":"Mahmoud","last_name":"Kalash","full_name":"Kalash, Mahmoud"},{"first_name":"Dennis","orcid":"0009-0007-5654-5412","last_name":"Scharwald","full_name":"Scharwald, Dennis","id":"55907"},{"first_name":"Polina","full_name":"Sharapova, Polina","id":"60286","last_name":"Sharapova"},{"last_name":"Lindlein","full_name":"Lindlein, Norbert","first_name":"Norbert"},{"first_name":"Maria","full_name":"Chekhova, Maria","last_name":"Chekhova"}],"volume":3,"year":"2025","citation":{"apa":"Barakat, I., Kalash, M., Scharwald, D., Sharapova, P., Lindlein, N., &#38; Chekhova, M.

Meanwhile, the existing methods of its characterization are technically complicated, which reduces the level of squeezing, and mostly deal with a single mode at a time. Here, for the first time, to the best of our knowledge, we employ optical parametric amplification to characterize multiple squeezing eigenmodes simultaneously. We retrieve the shapes and squeezing degrees of all modes at once through direct detection followed by modal decomposition. This method is tolerant to inefficient detection and does not require a local oscillator. For a spectrally and spatially multimode squeezed vacuum, we characterize eight strongest spatial modes, obtaining squeezing and anti-squeezing values of up to −5.2 ± 0.2 dB and 8.6 ± 0.3 dB, respectively, despite the 50% detection loss. This work, being the first exploration of an optical parametric amplifier’s multimode capability for squeezing detection, paves the way for the real-time detection of multimode squeezing."}],"status":"public","type":"journal_article","publication":"Optica Quantum"},{"year":"2025","issue":"3","title":"Entanglement between dependent degrees of freedom: Quasiparticle correlations","publisher":"American Physical Society (APS)","date_created":"2025-09-12T10:37:34Z","publication":"Physical Review A","language":[{"iso":"eng"}],"citation":{"ieee":"F.

Our theoretical approach is based on the formalism of Gaussian states and the Langevin equation, which is elaborated for weak parametric down-conversion and photon-number-unresolved click detection. Using the example of frequency-degenerate type-II SPDC generated under the pump-idler group-velocity-matching condition, we show how the joint-spectral intensity, mode structure, normalized second-order correlation function, and Hong-Ou-Mandel interference pattern depend on internal losses of the SPDC process. We found that the joint-spectral intensity is almost insensitive to internal losses, while the second-order correlation function shows a strong dependence on them, being different for the signal and idler beams in the presence of internal losses. Based on the sensitivity of the normalized second-order correlation function, we show how its measurement can be used to experimentally determine internal losses.</jats:p>","lang":"eng"}],"status":"public","type":"journal_article","publication":"Physical Review Research","title":"Spectral and temporal properties of type-II parametric down-conversion: The impact of losses during state generation","doi":"10.1103/zp72-7qwl","date_updated":"2025-12-05T09:55:22Z","publisher":"American Physical Society (APS)","author":[{"first_name":"Denis A.","last_name":"Kopylov","full_name":"Kopylov, Denis A."},{"first_name":"Michael","last_name":"Stefszky","id":"42777","full_name":"Stefszky, Michael"},{"last_name":"Meier","orcid":"0000-0001-8864-2072","full_name":"Meier, Torsten","id":"344","first_name":"Torsten"},{"full_name":"Silberhorn, Christine","id":"26263","last_name":"Silberhorn","first_name":"Christine"},{"last_name":"Sharapova","full_name":"Sharapova, Polina R.","id":"60286","first_name":"Polina R."}],"date_created":"2025-12-05T09:33:36Z","volume":7,"year":"2025","citation":{"ama":"Kopylov DA, Stefszky M, Meier T, Silberhorn C, Sharapova PR.

Going beyond isolated EPs, here we report on the existence of exceptional rings (ERs) in planar optical resonators with specific form of circular dichroism and TE-TM splitting. Such exceptional rings possess intriguing topologies as discussed earlier for condensed matter systems, but they remain virtually unexplored in presence of nonlinearity, for which our photonic platform is ideal. We find that when Kerr-type nonlinearity (or saturable gain) is introduced, the linear ER splits into two concentric ERs, with the larger-radius ring being a ring of third-order EPs. Transitioning from linear to nonlinear regime, we present a rigorous analysis of spectral topology and report enhanced and adjustable perturbation response in the nonlinear regime. Whereas certain features are specific to our system, the results on non-Hermitian spectral topology and nonlinearity-enhanced perturbation response are generic and equally relevant to a broad class of other nonlinear non-Hermitian systems, providing a universal framework for engineering ERs and EPs in nonlinear non-Hermitian systems."}],"type":"journal_article","publication":"Arxiv"},{"intvolume":"         7","citation":{"ama":"Kopylov DA, Offen C, Ares L, et al.

In this work, we theoretically study two-mode bipartite states, which are extracted from multimode light generated via type-II parametric downconversion (PDC) in lossy waveguides. For these states, we demonstrate that the squeezing quantifies entanglement and we construct a measurement basis, which results in the maximal bipartite entanglement. We illustrate our findings by numerically solving the spatial master equation for PDC in a Markovian environment. The optimal measurement modes are compared with two widely used broadband bases: the Mercer–Wolf basis (the first-order coherence basis) and the Williamson–Euler basis.</jats:p>","lang":"eng"}],"status":"public","project":[{"name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen","_id":"53"},{"_id":"56","name":"TRR 142 - Project Area C"},{"name":"TRR 142 ; TP: C10: Erzeugung und Charakterisierung von Quantenlicht in nichtlinearen Systemen: Eine theoretische Analyse","_id":"174"},{"_id":"266","name":"PhoQC: Photonisches Quantencomputing"}],"_id":"63562","user_id":"16199","department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"293"},{"_id":"429"},{"_id":"230"},{"_id":"623"},{"_id":"35"}],"article_number":"046116","language":[{"iso":"eng"}]},{"date_updated":"2024-07-09T10:29:29Z","publisher":"American Physical Society (APS)","volume":110,"date_created":"2024-07-09T10:27:33Z","author":[{"full_name":"Yasmin, Farha","last_name":"Yasmin","first_name":"Farha"},{"first_name":"Jan","full_name":"Sperling, Jan","id":"75127","last_name":"Sperling","orcid":"0000-0002-5844-3205"}],"title":"Entanglement-assisted quantum speedup: Beating local quantum speed limits","doi":"10.1103/physreva.110.012424","publication_identifier":{"issn":["2469-9926","2469-9934"]},"publication_status":"published","issue":"1","year":"2024","intvolume":"       110","citation":{"apa":"Yasmin, F., &#38; Sperling, J.
