  text: While plasmonic particles can provide optical resonances in a wide spectral
    range from the lower visible up to the near-infrared, often, symmetry effects
    are utilized to obtain particular optical responses. By breaking certain spatial
    symmetries, chiral structures arise and provide robust chiroptical responses to
    these plasmonic resonances. Here, we observe strong chiroptical responses in the
    linear and nonlinear optical regime for chiral L-handed helicoid-III nanoparticles
    and quantify them by means of an asymmetric factor, the so-called g-factor. We
    calculate the linear optical g-factors for two distinct chiroptical resonances
    to −0.12 and –0.43 and the nonlinear optical g-factors to −1.45 and −1.63. The
    results demonstrate that the chirality of the helicoid-III nanoparticles is strongly
    enhanced in the nonlinear regime.

  text: Optical geometric phase encoded by in-plane spatial orientation of microstructures
    has promoted the rapid development of numerous functional meta-devices. 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.

    is a promising platform for integrated quantum optics. In this platform, we aim
    to efficiently manipulate and detect quantum states by combining superconducting
    single photon detectors and modulators. The cryogenic operation of a superconducting
    single photon detector dictates the optimisation of the electro-optic modulators
    under the same operating conditions. To that end, we characterise a phase modulator,
    directional coupler, and polarisation converter at both ambient and cryogenic
    temperatures. The operation voltage <jats:inline-formula>\r\n                     <jats:tex-math><?CDATA

  text: <jats:p> Superconducting Nanowire Single Photon Detectors (SNSPDs) have become
    an integral part of quantum optics in recent years because of their high performance
    in single photon detection. 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>

  text: "The Quantum Singular Value Transformation (QSVT) is a recent technique that\r\ngives
    a unified framework to describe most quantum algorithms discovered so\r\nfar,
    and may lead to the development of novel quantum algorithms. 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."

  text: In this paper we give an overview over some aspects of the modern mathematical
    theory of Ruelle resonances for chaotic, i.e. uniformly hyperbolic, dynamical
    systems and their implications in physics. First we recall recent developments
    in the mathematical theory of resonances, in particular how invariant Ruelle distributions
    arise as residues of weighted zeta functions. 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. We finish by presenting
    numerical calculations of phase space distributions in the more physical setting
    of 3-disk scattering systems.
