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. In this work, motivated by\r\nestablishing the superiority of quantum algorithms for quantum chemistry and\r\nmaking progress on the quantum PCP conjecture, we focus on the other main class\r\nof matrices considered in applications of the QSVT, sparse matrices.\r\n  We first show how to efficiently \"dequantize\", with arbitrarily small\r\nconstant precision, the QSVT associated with a low-degree polynomial. 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 also discuss how this dequantization technique may help make\r\nprogress on the central quantum PCP conjecture."}],"publication":"Proceedings of the 54th ACM Symposium on Theory of Computing (STOC)","type":"conference","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2111.09079"}],"title":"Dequantizing the Quantum Singular Value Transformation: Hardness and  Applications to Quantum Chemistry and the Quantum PCP Conjecture","date_created":"2021-11-18T07:32:56Z","author":[{"last_name":"Gharibian","orcid":"0000-0002-9992-3379","full_name":"Gharibian, Sevag","id":"71541","first_name":"Sevag"},{"first_name":"François Le","last_name":"Gall","full_name":"Gall, François Le"}],"oa":"1","date_updated":"2023-10-09T04:17:29Z","page":"19-32","citation":{"ama":"Gharibian S, Gall FL.

Then we derive a correspondence between weighted and semiclassical zeta functions in the setting of negatively curved surfaces. Combining this with results of Hilgert, Guillarmou and Weich yields a high frequency interpretation of invariant Ruelle distributions as quantum mechanical matrix coefficients in constant negative curvature.

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."}],"publication":"Optical Materials Express","title":"Porous SiO2 coated dielectric metasurface with consistent performance independent of environmental conditions","date_created":"2021-12-02T18:47:42Z","publisher":"Optica","year":"2022","issue":"1","quality_controlled":"1"},{"publisher":"IOP Publishing","date_updated":"2023-04-20T14:51:09Z","author":[{"first_name":"Hendrik","full_name":"Rose, Hendrik","id":"55958","orcid":"0000-0002-3079-5428","last_name":"Rose"},{"full_name":"Tikhonova, O V","last_name":"Tikhonova","first_name":"O V"},{"first_name":"Torsten","id":"344","full_name":"Meier, Torsten","last_name":"Meier","orcid":"0000-0001-8864-2072"},{"id":"60286","full_name":"Sharapova, Polina","last_name":"Sharapova","first_name":"Polina"}],"date_created":"2023-01-18T10:56:13Z","volume":24,"title":"Steady states of Λ-type three-level systems excited by quantum light with various photon statistics in lossy cavities","doi":"10.1088/1367-2630/ac74d8","publication_status":"published","publication_identifier":{"issn":["1367-2630"]},"issue":"6","year":"2022","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>.","short":"H.

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>"}],"status":"public"},{"department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"623"},{"_id":"35"},{"_id":"429"}],"user_id":"16199","_id":"37319","project":[{"_id":"53","name":"TRR 142: TRR 142"},{"_id":"54","name":"TRR 142 - A: TRR 142 - Project Area A"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"article_number":"205408","type":"journal_article","status":"public","volume":106,"author":[{"full_name":"Grisard, S.","last_name":"Grisard","first_name":"S."},{"first_name":"Hendrik","full_name":"Rose, Hendrik","id":"55958","orcid":"0000-0002-3079-5428","last_name":"Rose"},{"full_name":"Trifonov, A.

Several different approaches to realize solid-state quantum emitters with high performance have been pursued and different concepts for energy tuning have been established. However, the properties of the emitted photons are always defined by the individual quantum emitter and can therefore not be controlled with full flexibility. Here we introduce an all-optical nonlinear method to tailor and control the single photon emission. We demonstrate a laser-controlled down-conversion process from an excited state of a semiconductor quantum three-level system. Based on this concept, we realize energy tuning and polarization control of the single photon emission with a control-laser field. Our results mark an important step towards tailored single photon emission from a photonic quantum system based on quantum optical principles.</jats:p>","lang":"eng"}],"publication":"Nature Communications","keyword":["General Physics and Astronomy","General Biochemistry","Genetics and Molecular Biology","General Chemistry","Multidisciplinary"],"language":[{"iso":"eng"}],"intvolume":"        13","citation":{"chicago":"Jonas, B., Dirk Florian Heinze, E.

Furthermore, we create so-called gray tracking in KTP and investigate the ionic conductivity in theses areas. A local unintended reduction of the ionic conductivity is observed in the gray-tracked regions, which also induce additional optical absorption in the material. We show that a thermal treatment in an oxygen-rich atmosphere removes the gray tracking and brings the ionic conductivity as well as the optical transmission back to the original level. These studies can help to choose the best material and treatment for specific applications."}],"type":"journal_article","publication":"Crystals","main_file_link":[{"open_access":"1"}],"doi":"10.3390/cryst12101359","title":"DC Ionic Conductivity in KTP and Its Isomorphs: Properties, Methods for Suppression, and Its Connection to Gray Tracking","author":[{"first_name":"Laura","id":"40300","full_name":"Padberg, Laura","last_name":"Padberg"},{"first_name":"Viktor","full_name":"Quiring, Viktor","last_name":"Quiring"},{"first_name":"Adriana","id":"58349","full_name":"Bocchini, Adriana","last_name":"Bocchini","orcid":"0000-0002-2134-3075"},{"full_name":"Santandrea, Matteo","id":"55095","last_name":"Santandrea","orcid":"0000-0001-5718-358X","first_name":"Matteo"},{"first_name":"Uwe","id":"171","full_name":"Gerstmann, Uwe","orcid":"0000-0002-4476-223X","last_name":"Gerstmann"},{"first_name":"Wolf Gero","id":"468","full_name":"Schmidt, Wolf Gero","last_name":"Schmidt","orcid":"0000-0002-2717-5076"},{"first_name":"Christine","last_name":"Silberhorn","full_name":"Silberhorn, Christine","id":"26263"},{"full_name":"Eigner, Christof","id":"13244","last_name":"Eigner","orcid":"https://orcid.org/0000-0002-5693-3083","first_name":"Christof"}],"date_created":"2022-09-26T13:12:48Z","volume":12,"date_updated":"2023-04-21T11:07:11Z","oa":"1","citation":{"ama":"Padberg L, Quiring V, Bocchini A, et al.

Recently, grafted perfect vortex beams (GPVBs) have attracted much attention due to their unique optical properties and potential applications. However, the current method to generate and manipulate GPVBs requires a complex and bulky optical system, hindering further investigation and limiting its practical applications. Here, a compact metasurface approach for generating and manipulating GPVBs in multiple channels is proposed and demonstrated, which eliminates the need for such a complex optical setup. A single metasurface is utilized to realize various superpositions of GPVBs with different combinations of topological charges in four channels, leading to asymmetric singularity distributions. The positions of singularities in the superimposed beam can be further modulated by introducing an initial phase difference in the metasurface design. The work demonstrates a compact metasurface platform that performs a sophisticated optical task that is very challenging with conventional optics, opening opportunities for the investigation and applications of GPVBs in a wide range of emerging application areas, such as singular optics and quantum science."}],"publication":"Advanced Materials","keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"language":[{"iso":"eng"}],"year":"2022","quality_controlled":"1","issue":"30","title":"Multichannel Superposition of Grafted Perfect Vortex Beams","publisher":"Wiley","date_created":"2022-06-20T11:05:50Z","status":"public","type":"journal_article","article_type":"original","article_number":"2203044","_id":"32068","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"user_id":"30525","intvolume":"        34","citation":{"chicago":"Ahmed, Hammad, Yuttana Intaravanne, Yang Ming, Muhammad Afnan Ansari, Gerald S.
