However, pushing the concept of the geometric phase toward the acoustic community still faces challenges. In this work, we utilize two acoustic nonlocal metagratings that could support a direct conversion between an acoustic plane wave and a designated vortex mode to obtain the acoustic geometric phase, in which an orbital angular momentum conversion process plays a vital role. In addition, we realize the acoustic geometric phases of different orders by merely varying the orientation angle of the acoustic nonlocal metagratings. Intriguingly, according to our developed theory, we reveal that the reflective acoustic geometric phase, which is twice the transmissive one, can be readily realized by transferring the transmitted configuration to a reflected one. Both the theoretical study and experimental measurements verify the announced transmissive and reflective acoustic geometric phases. Moreover, the reconfigurability and continuous phase modulation that covers the 2π range shown by the acoustic geometric phases provide us with the alternatives in advanced acoustic wavefront control.","lang":"eng"}],"language":[{"iso":"eng"}],"article_number":"211702","doi":"10.1063/5.0091474","publication_identifier":{"issn":["0003-6951","1077-3118"]},"author":[{"last_name":"Liu","first_name":"Bingyi","full_name":"Liu, Bingyi"},{"first_name":"Zhiling","last_name":"Zhou","full_name":"Zhou, Zhiling"},{"last_name":"Wang","first_name":"Yongtian","full_name":"Wang, Yongtian"},{"last_name":"Zentgraf","first_name":"Thomas","orcid":"0000-0002-8662-1101","full_name":"Zentgraf, Thomas","id":"30525"},{"full_name":"Li, Yong","last_name":"Li","first_name":"Yong"},{"full_name":"Huang, Lingling","last_name":"Huang","first_name":"Lingling"}],"title":"Experimental verification of the acoustic geometric phase","year":"2022","intvolume":"       120","date_updated":"2022-05-27T12:36:43Z","publication_status":"published"},{"citation":{"ieee":"Y.

We present a method to replace the electrical input by supplying the required bias current via the photocurrent of a photodiode situated on the cold stage of the cryostat. Light is guided to the bias photodiode through an optical fiber, which enables a lower thermal conduction and galvanic isolation between room temperature and the cold stage. We show that an off-the-shelf InGaAs–InP photodiode exhibits a responsivity of at least 0.55 A/W at 0.8 K. Using this device to bias an SNSPD, we characterize the count rate dependent on the optical power incident on the photodiode. This configuration of the SNSPD and photodiode shows an expected plateau in the single photon count rate with an optical bias power on the photodiode above 6.8 µW. Furthermore, we compare the same detector under both optical and electrical bias, and show there is no significant changes in performance. This has the advantage of avoiding an electrical input cable, which reduces the latent heat load by a factor of 100 and, in principle, allows for low loss RF current supply at the cold stage. </jats:p>","lang":"eng"}],"publication":"APL Photonics","issue":"8","keyword":["Computer Networks and Communications","Atomic and Molecular Physics","and Optics"],"type":"journal_article","department":[{"_id":"15"},{"_id":"230"},{"_id":"623"}],"date_created":"2022-10-11T07:15:09Z","publication_status":"published","date_updated":"2023-01-12T15:13:40Z","intvolume":"         7","year":"2022","title":"Opto-electronic bias of a superconducting nanowire single photon detector using a cryogenic photodiode","author":[{"id":"50819","first_name":"Frederik","orcid":"0000-0003-0663-5587","last_name":"Thiele","full_name":"Thiele, Frederik"},{"full_name":"Hummel, Thomas","last_name":"Hummel","first_name":"Thomas","id":"83846"},{"id":"46170","full_name":"Protte, Maximilian","first_name":"Maximilian","last_name":"Protte"},{"id":"49683","full_name":"Bartley, Tim","first_name":"Tim","last_name":"Bartley"}],"publication_identifier":{"issn":["2378-0967"]},"doi":"10.1063/5.0097506","article_number":"081303","language":[{"iso":"eng"}],"citation":{"mla":"Thiele, Frederik, et al. “Opto-Electronic Bias of a Superconducting Nanowire Single Photon Detector Using a Cryogenic Photodiode.” <i>APL Photonics</i>, vol. 7, no. 8, 081303, AIP Publishing, 2022, doi:<a href=\"https://doi.org/10.1063/5.0097506\">10.1063/5.0097506</a>.","bibtex":"@article{Thiele_Hummel_Protte_Bartley_2022, title={Opto-electronic bias of a superconducting nanowire single photon detector using a cryogenic photodiode}, volume={7}, DOI={<a href=\"https://doi.org/10.1063/5.0097506\">10.1063/5.0097506</a>}, number={8081303}, journal={APL Photonics}, publisher={AIP Publishing}, author={Thiele, Frederik and Hummel, Thomas and Protte, Maximilian and Bartley, Tim}, year={2022} }","ama":"Thiele F, Hummel T, Protte M, Bartley T.

In this paper\r\nwe investigate the hardness of classically simulating the QSVT. A recent result\r\nby Chia, Gily\\'en, Li, Lin, Tang and Wang (STOC 2020) showed that the QSVT can\r\nbe efficiently \"dequantized\" for low-rank matrices, and discussed its\r\nimplication to quantum machine learning.

We apply\r\nthis technique to design classical algorithms that estimate, with constant\r\nprecision, the singular values of a sparse matrix. We show in particular that a\r\ncentral computational problem considered by quantum algorithms for quantum\r\nchemistry (estimating the ground state energy of a local Hamiltonian when\r\ngiven, as an additional input, a state sufficiently close to the ground state)\r\ncan be solved efficiently with constant precision on a classical computer. As a\r\ncomplementary result, we prove that with inverse-polynomial precision, the same\r\nproblem becomes BQP-complete. This gives theoretical evidence for the\r\nsuperiority of quantum algorithms for chemistry, and strongly suggests that\r\nsaid superiority stems from the improved precision achievable in the quantum\r\nsetting.

We finish by presenting numerical calculations of phase space distributions in the more physical setting of 3-disk scattering systems."}],"date_created":"2022-05-04T12:23:11Z","department":[{"_id":"623"},{"_id":"548"},{"_id":"10"}],"type":"journal_article","status":"public","_id":"31057","publisher":"IOP Publishing Ltd","volume":55,"user_id":"49178","citation":{"mla":"Barkhofen, Sonja, et al. “Semiclassical Formulae For Wigner Distributions.” <i>Journal of Physics A: Mathematical and Theoretical</i>, vol. 55, no. 24, 244007, IOP Publishing Ltd, 2022, doi:<a href=\"https://doi.org/10.1088/1751-8121/ac6d2b\">10.1088/1751-8121/ac6d2b</a>.","ama":"Barkhofen S, Schütte P, Weich T.

However, the metasurfaces’ performance is tied to the unit cell’s efficiency and ultimately the surrounding environment it was designed for, thus reducing its applicability if exposed to altering refractive index media. Here, we report a method to increase a metasurface’s versatility by covering the high-index metasurface with a low index porous SiO2 film, protecting the metasurface from environmental changes while keeping the working efficiency unchanged. We show, that a covered metasurface retains its functionality even when exposed to fluidic environments.","lang":"eng"}]},{"doi":"10.1088/1367-2630/ac74d8","language":[{"iso":"eng"}],"article_number":"063020","intvolume":"        24","date_updated":"2023-04-20T14:51:09Z","publication_status":"published","publication_identifier":{"issn":["1367-2630"]},"author":[{"id":"55958","full_name":"Rose, Hendrik","last_name":"Rose","first_name":"Hendrik","orcid":"0000-0002-3079-5428"},{"first_name":"O V","last_name":"Tikhonova","full_name":"Tikhonova, O V"},{"full_name":"Meier, Torsten","first_name":"Torsten","last_name":"Meier","orcid":"0000-0001-8864-2072","id":"344"},{"id":"60286","full_name":"Sharapova, Polina","first_name":"Polina","last_name":"Sharapova"}],"title":"Steady states of Λ-type three-level systems excited by quantum light with various photon statistics in lossy cavities","year":"2022","department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"623"},{"_id":"35"}],"type":"journal_article","keyword":["General Physics and Astronomy"],"date_created":"2023-01-18T10:56:13Z","abstract":[{"lang":"eng","text":"<jats:title>Abstract</jats:title>\r\n               <jats:p>The interaction between quantum light and matter is being intensively studied for systems that are enclosed in high-<jats:italic>Q</jats:italic> cavities which strongly enhance the light–matter coupling. Cavities with low <jats:italic>Q</jats:italic>-factors are generally given less attention due to their high losses that quickly destroy quantum systems. However, bad cavities can be utilized for several applications, where lower <jats:italic>Q</jats:italic>-factors are required, e.g., to increase the spectral width of the cavity mode. In this work, we demonstrate that low-<jats:italic>Q</jats:italic> cavities can be beneficial for preparing specific electronic steady states when certain quantum states of light are applied. We investigate the interaction between quantum light with various statistics and matter represented by a Λ-type three-level system in lossy cavities, assuming that cavity losses are the dominant loss mechanism. We show that cavity losses lead to non-trivial electronic steady states that can be controlled by the loss rate and the initial statistics of the quantum fields. We discuss the mechanism of the formation of such steady states on the basis of the equations of motion and present both analytical expressions and numerical simulations for such steady states.</jats:p>"}],"publication":"New Journal of Physics","issue":"6","volume":24,"user_id":"16199","_id":"37318","publisher":"IOP Publishing","status":"public","project":[{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"citation":{"mla":"Rose, Hendrik, et al. “Steady States of Λ-Type Three-Level Systems Excited by Quantum Light with Various Photon Statistics in Lossy Cavities.” <i>New Journal of Physics</i>, vol. 24, no. 6, 063020, IOP Publishing, 2022, doi:<a href=\"https://doi.org/10.1088/1367-2630/ac74d8\">10.1088/1367-2630/ac74d8</a>.","ama":"Rose H, Tikhonova OV, Meier T, Sharapova P.
