  text: <jats:p>Stable and bright single photon sources are key components for future
    quantum applications. A simple fabrication method is an important requirement
    for such sources. Here, we present a single photon source based on diced ridge
    waveguides in titanium indiffused LiNbO<jats:sub>3</jats:sub>. These waveguides
    can be easily fabricated by combining planar titanium in-diffusion without lithographic
    patterning and easy-to-handle precision dicing. Such devices have the potential
    to generate high single photon rates because ridge structures are typically less
    prone to the photorefractive effect. We achieve waveguide propagation losses &lt;0.4dBcm
    and a SHG conversion efficiency of about 81%Wcm<jats:sup>2</jats:sup>. Harnessing
    a type-0 SPDC process to generate 1550 nm photons, we obtain a SPDC brightness
    of 3⋅10<jats:sup>5</jats:sup>1s⋅mW⋅nm, with a heralding efficiency of <jats:italic>η</jats:italic><jats:sub>h</jats:sub>=45%
    (<jats:italic>η</jats:italic><jats:sub>h,wg</jats:sub>=77.5% for the waveguide
    itself excluded setup losses) and a heralded second-order correlation function
    of <jats:italic>g</jats:italic><jats:sub>h</jats:sub><jats:sup>2</jats:sup>(0)&lt;0.003
    at low pump powers.</jats:p>

  text: <jats:p>Modulation conditioned on measurements on entangled photonic quantum
    states is a cornerstone technology of optical quantum information processing.
    Performing this task with low latency requires combining single-photon-level detectors
    with both electronic logic processing and optical modulation in close proximity.
    Here, we demonstrate low-latency feedforward using a quasi-photon-number-resolved
    measurement on a quantum light source. Specifically, we use a multipixel superconducting
    nanowire single-photon detector, amplifier, logic, and an integrated electro-optic
    modulator <jats:italic toggle="yes">in situ</jats:italic> below 4 K. We modulate
    the signal mode of a spontaneous parametric down-conversion source, conditional
    on a photon-number measurement of the idler mode, with a total latency of (23±3)ns.
    Furthermore, we investigate the resulting change in the photon statistics. This
    represents an important benchmark for the fastest quantum photonic feedforward
    experiments comprising measurement, amplification, logic, and modulation. This
    has direct applications in quantum computing, communication, and simulation protocols.</jats:p>

  text: The titanium in-diffused lithium niobate waveguide platform is well-established
    for reliable prototyping and packaging of many quantum photonic components at
    room temperature. Nevertheless, compatibility with certain quantum light sources
    and superconducting detectors requires operation under cryogenic conditions. We
    characterize alterations in phase-matching and mode guiding of a non-degenerate
    spontaneous parametric down-conversion process emitting around 1556 nm and 950 nm,
    under cryogenic conditions. Despite the effects of pyroelectricity and photorefraction,
    the spectral properties match our theoretical model. Nevertheless, these effects
    cause small but significant variations within and between cooling cycles. These
    measurements provide a first benchmark against which other nonlinear photonic
    integration platforms, such as thin-film lithium niobate, can be compared.

  text: Lithium niobate (LiNbO3) is a widely used material with several desirable
    physical properties, such as high second-order nonlinear optical and strong electro-optical
    effects. Thus LiNbO3 is used for various applications such as electro-optic modulation
    or nonlinear frequency conversion and mixing. But LiNbO3 also exhibits a strong
    photorefractive effect, which limits the intensity of the optical fields involved.
    Various approaches to reduce the photorefractive effect have been investigated,
    such as increasing the temperature, doping the crystal or using different waveguide
    designs in LiNbO3. Here, we present an analysis of the approach to increase the
    photorefractive damage threshold by using different waveguide designs. Contrary
    to previous claims and investigations, our SHG measurements revealed no significant
    difference in resistance to photorefractive damage when comparing conventional
    Ti-doped channel waveguides and Ti-doped diced ridge waveguides in LiNbO3. Furthermore,
    we have investigated the effect of photorefractive cleaning and curing using a
    light field at 532 nm. Here, we observe a reduction in the photorefractive effect
    at room temperature during and after SHG measurements, which is an easy alternative
    to conventional approaches.

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>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 LiNbO<jats:sub>3</jats:sub> 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.</jats:p>"

  text: <jats:p>Quantum photonic processing via electro-optic components typically
    requires electronic links across different operation environments, especially
    when interfacing cryogenic components such as superconducting single photon detectors
    with room-temperature control and readout electronics. However, readout and driving
    electronics can introduce detrimental parasitic effects. Here we show an all-optical
    control and readout of a superconducting nanowire single photon detector (SNSPD),
    completely electrically decoupled from room temperature electronics. We provide
    the operation power for the superconducting detector via a cryogenic photodiode,
    and readout single photon detection signals via a cryogenic electro-optic modulator
    in the same cryostat. This method opens the possibility for control and readout
    of superconducting circuits, and feedforward for photonic quantum computing.</jats:p>
