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>"}],"date_created":"2025-09-12T11:11:56Z","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"}],"status":"public","_id":"61252","publisher":"Wiley","user_id":"16199","volume":7,"citation":{"mla":"Bauch, David, et al. “On‐Demand Indistinguishable and Entangled Photons Using Tailored Cavity Designs.” <i>Advanced Quantum Technologies</i>, vol. 7, no. 1, 2300142, Wiley, 2023, doi:<a href=\"https://doi.org/10.1002/qute.202300142\">10.1002/qute.202300142</a>.","bibtex":"@article{Bauch_Siebert_Jöns_Förstner_Schumacher_2023, title={On‐Demand Indistinguishable and Entangled Photons Using Tailored Cavity Designs}, volume={7}, DOI={<a href=\"https://doi.org/10.1002/qute.202300142\">10.1002/qute.202300142</a>}, number={12300142}, journal={Advanced Quantum Technologies}, publisher={Wiley}, author={Bauch, David and Siebert, Dustin and Jöns, Klaus D. and Förstner, Jens and Schumacher, Stefan}, year={2023} }","ama":"Bauch D, Siebert D, Jöns KD, Förstner J, Schumacher S.

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>"}],"publication":"Optics Express","issue":"1","doi":"10.1364/oe.472058","language":[{"iso":"eng"}],"article_number":"610","intvolume":"        31","date_updated":"2025-12-11T13:05:14Z","publication_status":"published","publication_identifier":{"issn":["1094-4087"]},"author":[{"full_name":"Hummel, Thomas","orcid":"0000-0001-8627-2119","first_name":"Thomas","last_name":"Hummel","id":"83846"},{"first_name":"Alex","last_name":"Widhalm","full_name":"Widhalm, Alex"},{"first_name":"Jan Philipp","last_name":"Höpker","full_name":"Höpker, Jan Philipp","id":"33913"},{"full_name":"Jöns, Klaus","last_name":"Jöns","first_name":"Klaus","id":"85353"},{"last_name":"Chang","first_name":"Jin","full_name":"Chang, Jin"},{"full_name":"Fognini, Andreas","first_name":"Andreas","last_name":"Fognini"},{"full_name":"Steinhauer, Stephan","first_name":"Stephan","last_name":"Steinhauer"},{"full_name":"Zwiller, Val","last_name":"Zwiller","first_name":"Val"},{"orcid":"0000-0002-5190-0944","first_name":"Artur","last_name":"Zrenner","full_name":"Zrenner, Artur","id":"606"},{"first_name":"Tim","last_name":"Bartley","full_name":"Bartley, Tim","id":"49683"}],"title":"Nanosecond gating of superconducting nanowire single-photon detectors using cryogenic bias circuitry","year":"2023"},{"date_created":"2025-12-11T20:37:08Z","type":"journal_article","department":[{"_id":"623"},{"_id":"15"},{"_id":"230"}],"citation":{"short":"(2023).","chicago":"“Tunable Vector Beam Decoder by Inverse Design for High-Dimensional Quantum Key Distribution with 3D Polarized Spatial Modes,” 2023. <a href=\"https://doi.org/10.48550/ARXIV.2304.12296\">https://doi.org/10.48550/ARXIV.2304.12296</a>.","apa":"<i>Tunable vector beam decoder by inverse design for high-dimensional quantum key distribution with 3D polarized spatial modes</i>.

Avoiding multiple lasers and fibers for the distribution of the carrier and arbitrary signal from the base station to the frontend, and avoiding the laser diode for the IQ return path from receiver frontends to the base station reduces the hardware effort significantly.
