AB - Abstract
Lithium niobate has emerged as a promising platform for integrated quantum optics, enabling efficient generation, manipulation, and detection of quantum states of light. 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.

AB - Despite the fundamental role the Quantum Satisfiability (QSAT) problem has
played in quantum complexity theory, a central question remains open: At which
local dimension does the complexity of QSAT transition from "easy" to "hard"?
Here, we study QSAT with each constraint acting on a $k$-dimensional and
$l$-dimensional qudit pair, denoted $(k,l)$-QSAT. Our first main result shows
that, surprisingly, QSAT on qubits can remain $\mathsf{QMA}_1$-hard, in that
$(2,5)$-QSAT is $\mathsf{QMA}_1$-complete. In contrast, $2$-SAT on qubits is
well-known to be poly-time solvable [Bravyi, 2006]. Our second main result
proves that $(3,d)$-QSAT on the 1D line with $d\in O(1)$ is also
$\mathsf{QMA}_1$-hard. Finally, we initiate the study of 1D $(2,d)$-QSAT by
giving a frustration-free 1D Hamiltonian with a unique, entangled ground state.
Our first result uses a direct embedding, combining a novel clock
construction with the 2D circuit-to-Hamiltonian construction of [Gosset, Nagaj,
2013]. Of note is a new simplified and analytic proof for the latter (as
opposed to a partially numeric proof in [GN13]). This exploits Unitary Labelled
Graphs [Bausch, Cubitt, Ozols, 2017] together with a new "Nullspace Connection
Lemma", allowing us to break low energy analyses into small patches of
projectors, and to improve the soundness analysis of [GN13] from
$\Omega(1/T^6)$ to $\Omega(1/T^2)$, for $T$ the number of gates. Our second
result goes via black-box reduction: Given an arbitrary 1D Hamiltonian $H$ on
$d'$-dimensional qudits, we show how to embed it into an effective null-space
of a 1D $(3,d)$-QSAT instance, for $d\in O(1)$. Our approach may be viewed as a
weaker notion of "simulation" (\`a la [Bravyi, Hastings 2017], [Cubitt,
Montanaro, Piddock 2018]). As far as we are aware, this gives the first
"black-box simulation"-based $\mathsf{QMA}_1$-hardness result, i.e. for
frustration-free Hamiltonians.

AB - The Polynomial-Time Hierarchy ($\mathsf{PH}$) is a staple of classical
complexity theory, with applications spanning randomized computation to circuit
lower bounds to ''quantum advantage'' analyses for near-term quantum computers.
Quantumly, however, despite the fact that at least \emph{four} definitions of
quantum $\mathsf{PH}$ exist, it has been challenging to prove analogues for
these of even basic facts from $\mathsf{PH}$. This work studies three
quantum-verifier based generalizations of $\mathsf{PH}$, two of which are from
[Gharibian, Santha, Sikora, Sundaram, Yirka, 2022] and use classical strings
($\mathsf{QCPH}$) and quantum mixed states ($\mathsf{QPH}$) as proofs, and one
of which is new to this work, utilizing quantum pure states
($\mathsf{pureQPH}$) as proofs. We first resolve several open problems from
[GSSSY22], including a collapse theorem and a Karp-Lipton theorem for
$\mathsf{QCPH}$. Then, for our new class $\mathsf{pureQPH}$, we show one-sided
error reduction for $\mathsf{pureQPH}$, as well as the first bounds relating
these quantum variants of $\mathsf{PH}$, namely $\mathsf{QCPH}\subseteq
\mathsf{pureQPH} \subseteq \mathsf{EXP}^{\mathsf{PP}}$.

AB - AbstractFootball is one of the most played sports in the world and kicking with adequate accuracy increases the likelihood of winning a competition. Although studies with different target-directed movements underline the role of distinctive cortical activity on superior accuracy, little is known about cortical dynamics associated with kicking. Mobile electroencephalography is a popular tool to investigate cortical modulations during movement, however, inherent and artefact-related pitfalls may obscure the reliability of functional sources and their activity. The purpose of this study was therefore to describe consistent cortical dynamics underlying target-directed pass-kicks based on test–retest reliability estimates. Eleven participants performed a target-directed kicking task at two different sessions within one week. Electroencephalography was recorded using a 65-channel mobile system and behavioural data were collected including motion range, acceleration and accuracy performance. Functional sources were identified using independent component analysis and clustered in two steps with the components of first and subsequently both sessions. Reliability estimates of event-related spectral perturbations were computed pixel-wise for participants contributing with components of both sessions. The parieto-occipital and frontal clusters were reproducible for the same majority of the sample at both sessions. Their activity showed consistent alpha desyhronization and theta sychnronisation patterns with substantial reliability estimates revealing visual and attentional demands in different phases of kicking. The findings of our study reveal prominent cortical demands during the execution of a target-directed kick which may be considered in practical implementations and provide promising academic prospects in the comprehension and investigation of cortical activity associated with target-directed movements.
