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.","lang":"eng"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"706"},{"_id":"705"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"27"}],"user_id":"16199","_id":"60992","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen","_id":"53"},{"_id":"174","name":"TRR 142 ; TP: C10: Erzeugung und Charakterisierung von Quantenlicht in nichtlinearen Systemen: Eine theoretische Analyse"},{"name":"TRR 142 - Project Area C","_id":"56"}],"language":[{"iso":"eng"}]},{"language":[{"iso":"eng"}],"article_number":"033062","department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"293"},{"_id":"706"},{"_id":"636"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"623"}],"user_id":"16199","_id":"62980","project":[{"_id":"53","name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"},{"_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"}],"status":"public","abstract":[{"lang":"eng","text":"<jats:p>We introduce a new classification of multimode states with a fixed number of photons.

Although in the case of qubit systems, Bell measurements can be implemented using only linear optical components, the same result is no longer true for qudits, where at least the use of ancillary photons is required. In order to circumvent this limitation, one possibility is to introduce nonlinear effects. In this work, we adopt the latter approach and propose a scalable Bell measurement scheme for high-dimensional states, exploiting multiple squeezer devices applied to a linear optical circuit for discriminating the different Bell states. Our approach does not require ancillary photons, is not limited by the dimension of the quantum states, and is experimentally scalable, thus paving the way toward the realization of an effective high-dimensional Bell measurement.</jats:p>"}],"publisher":"American Physical Society (APS)","date_created":"2025-12-10T13:34:53Z","title":"Predetection squeezing as a resource for high-dimensional Bell-state measurements","issue":"2","year":"2025","_id":"63021","user_id":"75127","department":[{"_id":"623"},{"_id":"15"},{"_id":"170"},{"_id":"706"},{"_id":"429"}],"article_number":"023038","type":"journal_article","status":"public","date_updated":"2025-12-10T13:36:11Z","author":[{"first_name":"Luca","last_name":"Bianchi","full_name":"Bianchi, Luca"},{"full_name":"Marconi, Carlo","last_name":"Marconi","first_name":"Carlo"},{"first_name":"Jan","last_name":"Sperling","orcid":"0000-0002-5844-3205","id":"75127","full_name":"Sperling, Jan"},{"first_name":"Davide","full_name":"Bacco, Davide","last_name":"Bacco"}],"volume":7,"doi":"10.1103/physrevresearch.7.023038","publication_status":"published","publication_identifier":{"issn":["2643-1564"]},"citation":{"chicago":"Bianchi, Luca, Carlo Marconi, Jan Sperling, and Davide Bacco. “Predetection Squeezing as a Resource for High-Dimensional Bell-State Measurements.” <i>Physical Review Research</i> 7, no. 2 (2025). <a href=\"https://doi.org/10.1103/physrevresearch.7.023038\">https://doi.org/10.1103/physrevresearch.7.023038</a>.","ieee":"L.

In this work, a unification and extension of distinct forms of boson sampling is developed. The devised protocol merges discrete-variable scattershot boson sampling with continuous-variable Gaussian boson sampling. Therefore, it is rendered possible to harness the complexity of more interesting states, such as squeezed photons, in advanced sampling protocols. A generating function formalism is developed for the joint description of multiphoton and multimode light undergoing Gaussian transformations. The resulting analytical tools enable one to explore interfaces of different photonic quantum-information-processing platforms. A numerical simulation of unified sampling is carried out, benchmarking its performance, complexity, and scalability. Entanglement is characterized to exemplify the generation of quantum correlations from the nonlinear interactions of a unified sampler.</jats:p>","lang":"eng"}]},{"citation":{"short":"J. Pinske, J.

Observations, such as coherence times that exceed the nanosecond scale obtained by monitoring the temporal decay of quantum coherence in a polariton condensate, are discussed. Proof-of-concept experiments and numerical simulations that demonstrate the enhanced resourcefulness of the produced system states for modern quantum protocols are assessed.

In this contribution, the notion of a driven Gaussian quantum walk is introduced. In contrast to typically considered quantum walks in optical settings, we describe the operation of the walk in terms of a nonlinear map rather than a unitary operation, e.g., by replacing a beam-splitter-type coin with a two-mode squeezer, being a process that is controlled and driven by a pump field. This opens previously unattainable possibilities for quantum walks that include nonlinear elements as core components of their operation, vastly extending their range of applications. A full framework for driven Gaussian quantum walks is developed, including methods to dynamically characterize nonlinear, quantum, and quantum-nonlinear effects. Moreover, driven Gaussian quantum walks are compared with their classically interfering and linear counterparts, which are based on classical coherence of light rather than quantum superpositions. In particular, the generation and boost of highly multimode entanglement, squeezing, and other quantum effects are studied over the duration of the nonlinear walk. Importantly, we prove the quantumness of the evolution itself, regardless of the input state. A scheme for an experimental realization is proposed. Furthermore, nonlinear properties of driven Gaussian quantum walks are explored, such as amplification that leads to an ever increasing number of correlated quantum particles, constituting a source of new walkers during the walk. Therefore, a concept for quantum walks is proposed that leads to—and even produces—directly accessible quantum phenomena, and that renders the quantum simulation of nonlinear processes possible."}],"date_updated":"2026-01-09T09:50:22Z","volume":105,"author":[{"first_name":"Philip","last_name":"Held","full_name":"Held, Philip","id":"68236"},{"full_name":"Engelkemeier, Melanie","last_name":"Engelkemeier","first_name":"Melanie"},{"full_name":"De, Syamsundar","last_name":"De","first_name":"Syamsundar"},{"first_name":"Sonja","last_name":"Barkhofen","full_name":"Barkhofen, Sonja","id":"48188"},{"last_name":"Sperling","orcid":"0000-0002-5844-3205","full_name":"Sperling, Jan","id":"75127","first_name":"Jan"},{"first_name":"Christine","last_name":"Silberhorn","id":"26263","full_name":"Silberhorn, Christine"}],"doi":"10.1103/physreva.105.042210","main_file_link":[{"url":"https://journals.aps.org/pra/abstract/10.1103/PhysRevA.105.042210"}],"publication_identifier":{"issn":["2469-9926","2469-9934"]},"publication_status":"published","intvolume":"       105","citation":{"bibtex":"@article{Held_Engelkemeier_De_Barkhofen_Sperling_Silberhorn_2022, title={Driven Gaussian quantum walks}, volume={105}, DOI={<a href=\"https://doi.org/10.1103/physreva.105.042210\">10.1103/physreva.105.042210</a>}, number={4042210}, journal={Physical Review A}, publisher={American Physical Society (APS)}, author={Held, Philip and Engelkemeier, Melanie and De, Syamsundar and Barkhofen, Sonja and Sperling, Jan and Silberhorn, Christine}, year={2022} }","short":"P.
