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>"}],"issue":"1","publication":"Advanced Quantum Technologies","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"642"},{"_id":"61"},{"_id":"230"},{"_id":"35"},{"_id":"34"},{"_id":"429"},{"_id":"27"},{"_id":"623"}],"date_created":"2025-09-12T11:11:56Z","publication_status":"published","date_updated":"2025-09-12T11:16:12Z","intvolume":"         7","year":"2023","title":"On‐Demand Indistinguishable and Entangled Photons Using Tailored Cavity Designs","author":[{"last_name":"Bauch","first_name":"David","full_name":"Bauch, David"},{"full_name":"Siebert, Dustin","last_name":"Siebert","first_name":"Dustin"},{"full_name":"Jöns, Klaus D.","first_name":"Klaus D.","last_name":"Jöns","id":"85353"},{"id":"158","full_name":"Förstner, Jens","last_name":"Förstner","orcid":"0000-0001-7059-9862","first_name":"Jens"},{"id":"27271","full_name":"Schumacher, Stefan","orcid":"0000-0003-4042-4951","last_name":"Schumacher","first_name":"Stefan"}],"publication_identifier":{"issn":["2511-9044","2511-9044"]},"doi":"10.1002/qute.202300142","article_number":"2300142","language":[{"iso":"eng"}]},{"citation":{"ieee":"C.

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.

It is influenced by Miller’s (1990) framework of assessment in medical education and includes, among other aspects, performance assessments. This model is used to understand the potential effects of transferring assessment tools into a digital format with assessment feedback. Five examples for such a transfer will be discussed: three methods for various aspects of communication, a test for pedagogical content knowledge, and a test for content knowledge. All five are established instruments well-described in terms of validity. All five have recently been transferred into a digital format. The analysis of this transfer also reveals a potentially harmful effect of digital assessment. The closer an assessment instrument is to assessing action-related parts of professional competence, the more authenticity is required; however, digitisation tends to decrease this authenticity. This suggests that an increasing number of digital assessment tools in teacher education might result in an even more dominant focus on knowledge tests, ignoring other parts of professional competence. This article highlights the role of authenticity in validity and discusses the most suitable assessment format to address various parts of professional competence. It ends by highlighting the lessons learned from the transfer of assessment instruments into a digital format that other academic disciplines might find interesting.</jats:p>"}],"citation":{"ama":"Kulgemeyer C, Riese J, Vogelsang C, et al.

Combining these characteristics with temporal control of SNSPDs broadens their applications as in active de-latching for higher dynamic range counting or temporal filtering for pump-probe spectroscopy or LiDAR. To that end, we demonstrate active gating of an SNSPD with a minimum off-to-on rise time of 2.4 ns and a total gate length of 5.0 ns. We show how the rise time depends on the inductance of the detector in combination with the control electronics. The gate window is demonstrated to be fully and freely, electrically tunable up to 500 ns at a repetition rate of 1.0 MHz, as well as ungated, free-running operation. Control electronics to generate the gating are mounted on the 2.3 K stage of a closed-cycle sorption cryostat, while the detector is operated on the cold stage at 0.8 K. We show that the efficiency and timing jitter of the detector is not altered during the on-time of the gating window. We exploit gated operation to demonstrate a method to increase in the photon counting dynamic range by a factor 11.2, as well as temporal filtering of a strong pump in an emulated pump-probe experiment.</jats:p>","lang":"eng"}],"publication":"Optics Express","issue":"1"},{"type":"journal_article","department":[{"_id":"623"},{"_id":"15"},{"_id":"230"}],"date_created":"2025-12-11T20:37:08Z","abstract":[{"text":"Spatial modes of light have become highly attractive to increase the dimension and, thereby, security and information capacity in quantum key distribution (QKD).

For this reason, a considerable amount of engineering effort has been taken in order to improve the quality of particle sources and system components. At the same time, data analysis and collection methods based on post-selection have been used to mitigate the effect of particle losses. This has allowed for investigating experimentally multi-particle evolutions where the observer lacks knowledge about the system's intermediate propagation states. Nonetheless, the fundamental question how losses affect the behaviour of the surviving subset of a multi-particle system has not been investigated so far. For this reason, here we study the impact of particle losses in a quantum walk of two photons reconstructing the output probability distributions for one photon conditioned on the loss of the other in a known mode and temporal step of our evolution network. We present the underlying theoretical scheme that we have devised in order to model controlled particle losses, we describe an experimental platform capable of implementing our theory in a time multiplexing encoding. In the end we show how localized particle losses change the output distributions without altering their asymptotic spreading properties. Finally we devise a quantum civilization problem, a two walker generalisation of single particle recurrence processes.","lang":"eng"}],"date_created":"2023-03-02T09:53:59Z","type":"journal_article","department":[{"_id":"623"},{"_id":"15"},{"_id":"288"},{"_id":"169"}],"title":"Dynamic conditioning of two particle discrete-time quantum walks","year":"2023","publication_identifier":{"issn":["0031-8949","1402-4896"]},"author":[{"full_name":"Pegoraro, Federico","last_name":"Pegoraro","first_name":"Federico","id":"88928"},{"full_name":"Held, Philip","last_name":"Held","first_name":"Philip","id":"68236"},{"id":"48188","first_name":"Sonja","last_name":"Barkhofen","full_name":"Barkhofen, Sonja"},{"id":"27150","full_name":"Brecht, Benjamin","orcid":"0000-0003-4140-0556 ","first_name":"Benjamin","last_name":"Brecht"},{"last_name":"Silberhorn","first_name":"Christine","full_name":"Silberhorn, Christine","id":"26263"}],"publication_status":"published","date_updated":"2026-01-09T09:49:31Z","article_type":"original","intvolume":"        98","article_number":"034005","main_file_link":[{"url":"https://iopscience.iop.org/article/10.1088/1402-4896/acbcaa","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"10.1088/1402-4896/acbcaa","citation":{"bibtex":"@article{Pegoraro_Held_Barkhofen_Brecht_Silberhorn_2023, title={Dynamic conditioning of two particle discrete-time quantum walks}, volume={98}, DOI={<a href=\"https://doi.org/10.1088/1402-4896/acbcaa\">10.1088/1402-4896/acbcaa</a>}, number={3034005}, journal={Physica Scripta}, publisher={IOP Publishing}, author={Pegoraro, Federico and Held, Philip and Barkhofen, Sonja and Brecht, Benjamin and Silberhorn, Christine}, year={2023} }","ama":"Pegoraro F, Held P, Barkhofen S, Brecht B, Silberhorn C.
