Personalizing real‐world problems by (1) matching problems to students' shared living environment (context personalization) and (2) asking students to pose their own problems (active personalization) might be two interventions to increase students' task motivation.AimIn the current study, we investigated the effects of context personalization and active personalization on students' self‐efficacy expectations, intrinsic value, attainment value, utility value, and cost.SampleThe participants were 28 fifth‐ and sixth‐grade students who voluntarily took part in a six‐month afterschool program in which they posed problems with the aim of creating a math walk in their hometown.MethodUsing a within‐subjects design, at the end of the afterschool program, the students rated their self‐efficacy expectations and task values for four self‐developed problems associated with their hometown, four peer‐developed problems associated with their hometown, and four instructor‐provided problems associated with unfamiliar locations.ResultsStudents reported higher self‐efficacy expectations, intrinsic value, attainment value, and utility value for active‐personalized than non‐personalized problems. To a lesser extent, context personalization promoted intrinsic value and attainment value. No effect was found for cost.ConclusionsActive personalization (i.e. asking students to pose their own real‐world problems) is suited to enhance students' task motivation, specifically their self‐efficacy expectations, intrinsic value, attainment value, and utility value. Context personalization still boosts students' intrinsic value and attainment value. Implementation in classroom instruction is discussed. author: - first_name: Johanna full_name: Schoenherr, Johanna last_name: Schoenherr citation: ama: 'Schoenherr J.

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." article_number: '015402' author: - first_name: Frederik full_name: Thiele, Frederik id: '50819' last_name: Thiele orcid: 0000-0003-0663-5587 - first_name: Thomas full_name: Hummel, Thomas id: '83846' last_name: Hummel - first_name: Nina Amelie full_name: Lange, Nina Amelie id: '56843' last_name: Lange orcid: 0000-0001-6624-7098 - first_name: Felix full_name: Dreher, Felix last_name: Dreher - first_name: Maximilian full_name: Protte, Maximilian last_name: Protte - first_name: Felix vom full_name: Bruch, Felix vom last_name: Bruch - first_name: Sebastian full_name: Lengeling, Sebastian id: '44373' last_name: Lengeling - first_name: Harald full_name: Herrmann, Harald id: '216' last_name: Herrmann - first_name: Christof full_name: Eigner, Christof id: '13244' last_name: Eigner orcid: https://orcid.org/0000-0002-5693-3083 - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn - first_name: Tim full_name: Bartley, Tim id: '49683' last_name: Bartley citation: ama: Thiele F, Hummel T, Lange NA, 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." author: - first_name: Dorian full_name: Rudolph, Dorian last_name: Rudolph - first_name: Sevag full_name: Gharibian, Sevag id: '71541' last_name: Gharibian orcid: 0000-0002-9992-3379 - first_name: Daniel full_name: Nagaj, Daniel last_name: Nagaj citation: ama: Rudolph D, Gharibian S, Nagaj D.

This work studies three\r\nquantum-verifier based generalizations of $\\mathsf{PH}$, two of which are from\r\n[Gharibian, Santha, Sikora, Sundaram, Yirka, 2022] and use classical strings\r\n($\\mathsf{QCPH}$) and quantum mixed states ($\\mathsf{QPH}$) as proofs, and one\r\nof which is new to this work, utilizing quantum pure states\r\n($\\mathsf{pureQPH}$) as proofs. We first resolve several open problems from\r\n[GSSSY22], including a collapse theorem and a Karp-Lipton theorem for\r\n$\\mathsf{QCPH}$. Then, for our new class $\\mathsf{pureQPH}$, we show one-sided\r\nerror reduction for $\\mathsf{pureQPH}$, as well as the first bounds relating\r\nthese quantum variants of $\\mathsf{PH}$, namely $\\mathsf{QCPH}\\subseteq\r\n\\mathsf{pureQPH} \\subseteq \\mathsf{EXP}^{\\mathsf{PP}}$." author: - first_name: Avantika full_name: Agarwal, Avantika last_name: Agarwal - first_name: Sevag full_name: Gharibian, Sevag id: '71541' last_name: Gharibian orcid: 0000-0002-9992-3379 - first_name: Venkata full_name: Koppula, Venkata last_name: Koppula - first_name: Dorian full_name: Rudolph, Dorian last_name: Rudolph citation: ama: 'Agarwal A, Gharibian S, Koppula V, Rudolph D.
