Here, we investigate spectral topology and EPs in systems with significant nonlinearity, exemplified by a nonequilibrium exciton-polariton condensate. With the possibility to control loss and gain and nonlinearity by optical means, this system allows for a comprehensive analysis of the interplay of nonlinearities (Kerr type and saturable gain) and non-Hermiticity. Not only do we find that EPs can be intentionally shifted in parameter space by the saturable gain, but we also observe intriguing rotations and intersections of Riemann surfaces and find nonlinearity-enhanced sensing capabilities. With this, our results illustrate the potential of tailoring spectral topology and related phenomena in non-Hermitian systems by nonlinearity.</jats:p>\r\n          <jats:sec>\r\n            <jats:title/>\r\n            <jats:supplementary-material>\r\n              <jats:permissions>\r\n                <jats:copyright-statement>Published by the American Physical Society</jats:copyright-statement>\r\n                <jats:copyright-year>2024</jats:copyright-year>\r\n              </jats:permissions>\r\n            </jats:supplementary-material>\r\n          </jats:sec>","lang":"eng"}],"user_id":"16199","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"705"},{"_id":"35"},{"_id":"230"},{"_id":"27"},{"_id":"429"}],"project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"_id":"53","name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"},{"name":"TRR 142 - Project Area A","_id":"54"},{"_id":"61","name":"TRR 142; TP A04: Nichtlineare Quantenprozesstomographie und Photonik mit Polaritonen in Mikrokavitäten"}],"_id":"61257","language":[{"iso":"eng"}],"article_number":"013148","issue":"1","publication_status":"published","publication_identifier":{"issn":["2643-1564"]},"citation":{"apa":"Wingenbach, J., Schumacher, S., &#38; Ma, X.

Here, a novel n‐dopant, phosphazenium tetrafluoroborate (P<jats:sub>2</jats:sub>BF<jats:sub>4</jats:sub>) is introduced, which effectively induces n‐doping in N2200, P(PzDPP‐CT2) and several other commonly used OSCs. Remarkably, the electrical conductivity of P<jats:sub>2</jats:sub>BF<jats:sub>4</jats:sub>‐doped OSC films remains almost unchanged even after heating at temperatures &gt; 150 °C for 24 h, far superior to the films doped with benchmark N‐DMBI. The exceptional thermal stability observed in P<jats:sub>2</jats:sub>BF<jats:sub>4</jats:sub>‐doped P(PzDPP‐CT2) films allows for stable operation of the corresponding organic thermoelectric devices at 150 °C for 16 h, a milestone not previously achieved.

We explicitly demonstrate the theoretical generation of linear cluster states with substantial numbers of entangled photonic qubits in full microscopic numerical simulations. The underlying scheme is based on the manipulation of ground state coherences through precise optical driving. One important finding is that the most easily accessible quality metrics, the achievable rotation fidelities, fall short in assessing the actual quantum correlations of the emitted photons in the face of losses. To address this, we explicitly calculate stabilizer generator expectation values as a superior gauge for the quantum properties of the generated many-photon state. With widespread applicability in other emitter and excitation–emission schemes also, our work lays the conceptual foundations for an in-depth practical analysis of time-bin entanglement based on full numerical simulations with predictive capabilities for realistic systems and setups, including losses and imperfections. The specific results shown in the present work illustrate that with controlled minimization of losses and realistic system parameters for quantum-dot type systems, useful linear cluster states of significant lengths can be generated in the calculations, discussing the possibility of scalability for quantum information processing endeavors.</jats:p>","lang":"eng"}],"status":"public","publication":"APL Quantum","type":"journal_article"},{"publication":"arXiv:2409.19167","type":"preprint","status":"public","abstract":[{"text":"Phonons in solid-state quantum emitters play a crucial role in their performance as photon sources in quantum technology.

In the present work, it focuses on the generation of pairs of photons with high degrees of polarization entanglement and simultaneously high indistinguishability. It achieves this goal by selectively reducing the biexciton lifetime with an optical resonator. It demonstrates that a suitably tailored circular Bragg reflector fulfills the requirements of sufficient selective Purcell enhancement of biexciton emission paired with spectrally broad photon extraction and twofold degenerate optical modes. The in‐depth theoretical study combines (i) the optimization of realistic photonic structures solving Maxwell's equations from which model parameters are extracted as input for (ii) microscopic simulations of quantum‐dot cavity excitation dynamics with full access to photon properties. It reports non‐trivial dependencies on system parameters and use the predictive power of the combined theoretical approach to determine the optimal range of Purcell enhancement that maximizes indistinguishability and entanglement to near unity values, here specifically for the telecom C‐band at 1550 nm.</jats:p>","lang":"eng"}],"publication":"Advanced Quantum Technologies","language":[{"iso":"eng"}],"year":"2023","issue":"1","title":"On‐Demand Indistinguishable and Entangled Photons Using Tailored Cavity Designs","publisher":"Wiley","date_created":"2025-09-12T11:11:56Z","status":"public","type":"journal_article","article_number":"2300142","_id":"61252","project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"},{"_id":"53","name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"},{"name":"TRR 142 - Project Area B","_id":"55"},{"_id":"56","name":"TRR 142 - Project Area C"},{"name":"TRR 142; TP B06: Ultraschnelle kohärente opto-elektronische Kontrolle eines photonischen Quantensystems","_id":"167"},{"name":"TRR 142; TP C09: Ideale Erzeugung von Photonenpaaren für Verschränkungsaustausch bei Telekom Wellenlängen","_id":"173"},{"_id":"266","name":"PhoQC: Photonisches Quantencomputing"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"642"},{"_id":"61"},{"_id":"230"},{"_id":"35"},{"_id":"34"},{"_id":"429"},{"_id":"27"},{"_id":"623"}],"user_id":"16199","intvolume":"         7","citation":{"ieee":"D.

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.
