  text: <jats:p>Nonlinear SU(1,1) interferometers are fruitful and promising tools
    for spectral engineering and precise measurements with phase sensitivity below
    the classical bound. Such interferometers have been successfully realized in bulk
    and fiber-based configurations. However, rapidly developing integrated technologies
    provide higher efficiencies, smaller footprints, and pave the way to quantum-enhanced
    on-chip interferometry. In this work, we theoretically realised an integrated
    architecture of the multimode SU(1,1) interferometer which can be applied to various
    integrated platforms. The presented interferometer includes a polarization converter
    between two photon sources and utilizes a continuous-wave (CW) pump. Based on
    the potassium titanyl phosphate (KTP) platform, we show that this configuration
    results in almost perfect destructive interference at the output and supersensitivity
    regions below the classical limit. In addition, we discuss the fundamental difference
    between single-mode and highly multimode SU(1,1) interferometers in the properties
    of phase sensitivity and its limits. Finally, we explore how to improve the phase
    sensitivity by filtering the output radiation and using different seeding states
    in different modes with various detection strategies.</jats:p>

  text: We experimentally investigate the generation of continuous-wave optical squeezing
    from a titanium-indiffused lithium niobate waveguide resonator at low and high
    frequencies. The device promises integration with different platform chips for
    more complex optical systems.

  text: <jats:p>Hybrid quantum information processing combines the advantages of discrete
    and continues variable protocols by realizing protocols consisting of photon counting
    and homodyne measurements. However, the mode structure of pulsed sources and the
    properties of the detection schemes often require the use of optical filters in
    order to combine both detection methods in a common experiment. This limits the
    efficiency and the overall achievable squeezing of the experiment. In our work,
    we use photon subtraction to implement the distillation of pulsed squeezed states
    originating from a genuinely spatially and temporally single-mode parametric down-conversion
    source in non-linear waveguides. Due to the distillation, we witness an improvement
    of 0.17 dB from an initial squeezing value of −1.648 ± 0.002 dB, while achieving
    a purity of 0.58, and confirm the non-Gaussianity of the distilled state via the
    higher-order cumulants. With this, we demonstrate the source’s suitability for
    scalable hybrid quantum network applications with pulsed quantum light.</jats:p>

  text: "Polarons in dielectric crystals play a crucial role for applications in integrated
    electronics and optoelectronics. In this work, we use density-functional theory
    and Green's function methods to explore the microscopic structure and spectroscopic
    signatures of electron polarons in lithium niobate (LiNbO3). Total-energy calculations
    and the comparison of calculated electron paramagnetic resonance data with available
    measurements reveal the formation of bound \r\npolarons at Nb_Li antisite defects
    with a quasi-Jahn-Teller distorted, tilted configuration. The defect-formation
    energies further indicate that (bi)polarons may form not only at \r\nNb_Li antisites
    but also at structures where the antisite Nb atom moves into a neighboring empty
    oxygen octahedron. Based on these structure models, and on the calculated charge-transition
    levels and potential-energy barriers, we propose two mechanisms for the optical
    and thermal splitting of bipolarons, which provide a natural explanation for the
    reported two-path recombination of bipolarons. Optical-response calculations based
    on the Bethe-Salpeter equation, in combination with available experimental data
    and new measurements of the optical absorption spectrum, further corroborate the
    geometries proposed here for free and defect-bound (bi)polarons."
