However, integrating single-photon detectors requires cryogenic operating temperatures, since the best performing detectors are based on narrow superconducting wires. While previous studies have demonstrated the operation of quantum light sources and electro-optic modulators in LiNbO3 at cryogenic temperatures, the thermal transition between room temperature and cryogenic conditions introduces additional effects that can significantly influence device performance. In this paper, we investigate the generation of pyroelectric charges and their impact on the optical properties of lithium niobate waveguides when changing from room temperature to 25 K, and vice versa. We measure the generated pyroelectric charge flow and correlate this with fast changes in the birefringence acquired through the Sénarmont-method. Both electrical and optical influence of the pyroelectric effect occur predominantly at temperatures above 100 K.","lang":"eng"}],"volume":4,"status":"public","date_created":"2024-02-16T07:56:44Z","publisher":"IOP Publishing","author":[{"first_name":"Frederik","orcid":"0000-0003-0663-5587","full_name":"Thiele, Frederik","last_name":"Thiele","id":"50819"},{"last_name":"Hummel","id":"83846","first_name":"Thomas","full_name":"Hummel, Thomas"},{"last_name":"Lange","id":"56843","first_name":"Nina Amelie","full_name":"Lange, Nina Amelie","orcid":"0000-0001-6624-7098"},{"last_name":"Dreher","full_name":"Dreher, Felix","first_name":"Felix"},{"last_name":"Protte","full_name":"Protte, Maximilian","first_name":"Maximilian"},{"first_name":"Felix vom","full_name":"Bruch, Felix vom","last_name":"Bruch"},{"first_name":"Sebastian","full_name":"Lengeling, Sebastian","last_name":"Lengeling","id":"44373"},{"id":"216","last_name":"Herrmann","full_name":"Herrmann, Harald","first_name":"Harald"},{"last_name":"Eigner","id":"13244","first_name":"Christof","orcid":"https://orcid.org/0000-0002-5693-3083","full_name":"Eigner, Christof"},{"last_name":"Silberhorn","id":"26263","first_name":"Christine","full_name":"Silberhorn, Christine"},{"first_name":"Tim","full_name":"Bartley, Tim","last_name":"Bartley","id":"49683"}],"keyword":["General Earth and Planetary Sciences","General Environmental Science"],"publication":"Materials for Quantum Technology","doi":"10.1088/2633-4356/ad207d","date_updated":"2024-03-04T13:20:43Z","language":[{"iso":"eng"}],"title":"Pyroelectric influence on lithium niobate during the thermal transition for cryogenic integrated photonics","publication_status":"published","publication_identifier":{"issn":["2633-4356"]}},{"_id":"51132","date_updated":"2024-02-06T10:11:31Z","year":"2024","type":"book","citation":{"bibtex":"@book{Seitz_Hamacher_Schieffer_Bunte_2024, place={Frankfurt am Main}, title={Qualitätsoffensive Ganztag - Praktische Methoden für den Weg zur guten Ganztagsbildung}, publisher={Debus Pädagogik}, author={Seitz, Simone and Hamacher, Catalina and Schieffer, Leonie and Bunte, Charline}, year={2024} }","mla":"Seitz, Simone, et al.

Our first main result shows\r\nthat, surprisingly, QSAT on qubits can remain $\\mathsf{QMA}_1$-hard, in that\r\n$(2,5)$-QSAT is $\\mathsf{QMA}_1$-complete. In contrast, $2$-SAT on qubits is\r\nwell-known to be poly-time solvable [Bravyi, 2006]. Our second main result\r\nproves that $(3,d)$-QSAT on the 1D line with $d\\in O(1)$ is also\r\n$\\mathsf{QMA}_1$-hard. Finally, we initiate the study of 1D $(2,d)$-QSAT by\r\ngiving a frustration-free 1D Hamiltonian with a unique, entangled ground state.\r\n Our first result uses a direct embedding, combining a novel clock\r\nconstruction with the 2D circuit-to-Hamiltonian construction of [Gosset, Nagaj,\r\n2013]. Of note is a new simplified and analytic proof for the latter (as\r\nopposed to a partially numeric proof in [GN13]). This exploits Unitary Labelled\r\nGraphs [Bausch, Cubitt, Ozols, 2017] together with a new \"Nullspace Connection\r\nLemma\", allowing us to break low energy analyses into small patches of\r\nprojectors, and to improve the soundness analysis of [GN13] from\r\n$\\Omega(1/T^6)$ to $\\Omega(1/T^2)$, for $T$ the number of gates. Our second\r\nresult goes via black-box reduction: Given an arbitrary 1D Hamiltonian $H$ on\r\n$d'$-dimensional qudits, we show how to embed it into an effective null-space\r\nof a 1D $(3,d)$-QSAT instance, for $d\\in O(1)$. Our approach may be viewed as a\r\nweaker notion of \"simulation\" (\\`a la [Bravyi, Hastings 2017], [Cubitt,\r\nMontanaro, Piddock 2018]). As far as we are aware, this gives the first\r\n\"black-box simulation\"-based $\\mathsf{QMA}_1$-hardness result, i.e. for\r\nfrustration-free Hamiltonians."}],"external_id":{"arxiv":["2401.02368"]},"user_id":"71541","title":"Quantum 2-SAT on low dimensional systems is $\\mathsf{QMA}_1$-complete: Direct embeddings and black-box simulation"},{"date_created":"2024-01-07T20:09:32Z","status":"public","publication":"arXiv:2401.01633","author":[{"first_name":"Avantika","full_name":"Agarwal, Avantika","last_name":"Agarwal"},{"id":"71541","last_name":"Gharibian","orcid":"0000-0002-9992-3379","full_name":"Gharibian, Sevag","first_name":"Sevag"},{"last_name":"Koppula","first_name":"Venkata","full_name":"Koppula, Venkata"},{"first_name":"Dorian","full_name":"Rudolph, Dorian","last_name":"Rudolph"}],"user_id":"71541","title":"Quantum Polynomial Hierarchies: Karp-Lipton, error reduction, and lower bounds","abstract":[{"text":"The Polynomial-Time Hierarchy ($\\mathsf{PH}$) is a staple of classical\r\ncomplexity theory, with applications spanning randomized computation to circuit\r\nlower bounds to ''quantum advantage'' analyses for near-term quantum computers.\r\nQuantumly, however, despite the fact that at least \\emph{four} definitions of\r\nquantum $\\mathsf{PH}$ exist, it has been challenging to prove analogues for\r\nthese of even basic facts from $\\mathsf{PH}$.
