  text: <jats:p>Frequency-filtered photon correlations have been proven to be extremely
    useful in grasping how the detection process alters photon statistics. Harnessing
    the spectral correlations also permits refinement of the emission and unraveling
    of previously hidden strong correlations in a plethora of quantum-optical systems
    under continuous-wave excitation. In this work, we investigate such correlations
    for time-dependent excitation and develop a methodology to compute efficiently
    time-integrated correlations, which are at the heart of the photon-counting theory,
    and subsequently apply it to analyze the photon emission of pulsed systems. By
    combining this formalism with the —which facilitates frequency-resolved correlations—we
    demonstrate how spectral filtering enhances single-photon purity and suppresses
    multiphoton noise in time-bin-encoded quantum states. Specifically, filtering
    the central spectral peak of a dynamically driven two-level system boosts temporal
    coherence and improves the fidelity of time-bin entanglement preparation, even
    under conditions favoring multiphoton emission. These results establish spectral
    filtering as a critical tool for tailoring photon statistics in pulsed quantum
    light sources.</jats:p>

  text: <jats:title>Abstract</jats:title><jats:p>Most properties of solid materials
    are defined by their internal electric field and charge density distributions
    which so far are difficult to measure with high spatial resolution. Especially
    for 2D materials, the atomic electric fields influence the optoelectronic properties.
    In this study, the atomic‐scale electric field and charge density distribution
    of WSe<jats:sub>2</jats:sub> bi‐ and trilayers are revealed using an emerging
    microscopy technique, differential phase contrast (DPC) imaging in scanning transmission
    electron microscopy (STEM). For pristine material, a higher positive charge density
    located at the selenium atomic columns compared to the tungsten atomic columns
    is obtained and tentatively explained by a coherent scattering effect. Furthermore,
    the change in the electric field distribution induced by a missing selenium atomic
    column is investigated. A characteristic electric field distribution in the vicinity
    of the defect with locally reduced magnitudes compared to the pristine lattice
    is observed. This effect is accompanied by a considerable inward relaxation of
    the surrounding lattice, which according to first principles DFT calculation is
    fully compatible with a missing column of Se atoms. This shows that DPC imaging,
    as an electric field sensitive technique, provides additional and remarkable information
    to the otherwise only structural analysis obtained with conventional STEM imaging.</jats:p>

  text: "<jats:title>Abstract</jats:title>\r\n                  <jats:p>Developing
    coherent excitation methods for quantum emitters ensuring high brightness, optimal
    single‐photon purity and indistinguishability of the emitted photons has been
    a key challenge in the past years. While various methods have been proposed and
    explored, they all have specific advantages and disadvantages. This study investigates
    the dynamics of the recent swing‐up scheme as an excitation method for a two‐level
    system and its performance in single‐photon generation. By applying two far red‐detuned
    laser pulses, the two‐level system can be prepared in the excited state with near‐unity
    fidelity. The successful operation and coherent character of this technique are
    demonstrated using a semiconductor quantum dot (QD). Moreover, the multi‐dimensional
    parameter space of the two laser pulses is explored to analyze its impact on excitation
    fidelity. Finally, the performance of the scheme as an excitation method for generating
    high‐quality single photons is analyzed. The swing‐up scheme itself proves effective,
    exhibiting nearly perfect single‐photon purity, while the observed indistinguishability
    in the studied sample is limited by the influence of the inevitable high excitation
    powers on the semiconductor environment of the quantum dot.</jats:p>"

  text: Phonons in solid-state quantum emitters play a crucial role in their performance
    as photon sources in quantum technology. For resonant driving, phonons dampen
    the Rabi oscillations resulting in reduced preparation fidelities. The phonon
    spectral density, which quantifies the strength of the carrier-phonon interaction,
    is non-monotonous as a function of energy. As one of the most prominent consequences,
    this leads to the reappearance of Rabi rotations for increasing pulse power, which
    was theoretically predicted in Phys. Rev. Lett. 98, 227403 (2007). In this paper
    we present the experimental demonstration of the reappearance of Rabi rotations.

  text: On-chip emitters that can generate single and entangled photons are essential
    building blocks for developing photonic quantum information processing technologies
    in a scalable fashion. Semiconductor quantum dots (QDs) are attractive candidates
    that emit high-quality quantum states of light on demand, however at a rate limited
    by their spontaneous radiative lifetime. In this study, we utilize the Purcell
    effect to demonstrate up to a 38-fold enhancement in the emission rate of InAs
    QDs by coupling them to metal-clad GaAs nanopillars. These cavities, featuring
    a sub-wavelength mode volume of 4.5x10-4 (λ/n)3 and low quality factor of 62,
    enable Purcell-enhanced single-photon emission across a large bandwidth of 15
    nm. The broadband nature of the cavity eliminates the need for implementing tuning
    mechanisms typically required to achieve QD-cavity resonance, thus relaxing fabrication
    constraints. Ultimately, this QD-cavity architecture represents a significant
    stride towards developing solid-state quantum emitters generating near-ideal single-photon
    states at GHz-level repetition rates.

  text: "Long-range quantum communication requires the development of in-out\r\nlight-matter
    interfaces to achieve a quantum advantage in entanglement\r\ndistribution. Ideally,
    these quantum interconnections should be as fast as\r\npossible to achieve high-rate
    entangled qubits distribution. Here, we\r\ndemonstrate the coherent quanta exchange
    between single photons generated\r\non-demand from a GaAs quantum dot and atomic
    ensemble in a $^{87}$Rb vapor\r\nquantum memory. Through an open quantum system

  text: <jats:title>Abstract</jats:title><jats:p>The biexciton‐exciton emission cascade
    commonly used in quantum‐dot systems to generate polarization entanglement yields
    photons with intrinsically limited indistinguishability. In the present work,
    it focuses on the generation of pairs of photons with high degrees of polarization
    entanglement and simultaneously high indistinguishability. It achieves this goal
    by selectively reducing the biexciton lifetime with an optical resonator. It demonstrates
    that a suitably tailored circular Bragg reflector fulfills the requirements of
    sufficient selective Purcell enhancement of biexciton emission paired with spectrally
    broad photon extraction and twofold degenerate optical modes. The in‐depth theoretical
    study combines (i) the optimization of realistic photonic structures solving Maxwell's
    equations from which model parameters are extracted as input for (ii) microscopic
    simulations of quantum‐dot cavity excitation dynamics with full access to photon
    properties. It reports non‐trivial dependencies on system parameters and use the
    predictive power of the combined theoretical approach to determine the optimal
    range of Purcell enhancement that maximizes indistinguishability and entanglement
    to near unity values, here specifically for the telecom C‐band at 1550 nm.</jats:p>

  text: <jats:p>Superconducting nanowire single-photon detectors (SNSPDs) show near
    unity efficiency, low dark count rate, and short recovery time. Combining these
    characteristics with temporal control of SNSPDs broadens their applications as
    in active de-latching for higher dynamic range counting or temporal filtering
    for pump-probe spectroscopy or LiDAR. To that end, we demonstrate active gating
    of an SNSPD with a minimum off-to-on rise time of 2.4 ns and a total gate length
    of 5.0 ns. We show how the rise time depends on the inductance of the detector
    in combination with the control electronics. The gate window is demonstrated to
    be fully and freely, electrically tunable up to 500 ns at a repetition rate of
    1.0 MHz, as well as ungated, free-running operation. Control electronics to generate
    the gating are mounted on the 2.3 K stage of a closed-cycle sorption cryostat,
    while the detector is operated on the cold stage at 0.8 K. We show that the efficiency
    and timing jitter of the detector is not altered during the on-time of the gating
    window. We exploit gated operation to demonstrate a method to increase in the
    photon counting dynamic range by a factor 11.2, as well as temporal filtering
    of a strong pump in an emulated pump-probe experiment.</jats:p>

  text: "Long range quantum communication and quantum information processing require\r\nthe
    development of light-matter interfaces for distributed quantum networks.\r\nEven
    though photons are ideal candidates for network links to transfer quantum\r\ninformation,
    the system of choice for the realization of quantum nodes has not\r\nbeen identified
    yet. Ideally, one strives for a hybrid network architecture,\r\nwhich will consist
    of different quantum systems, combining the strengths of\r\neach system. However,
    interfacing different quantum systems via photonic\r\nchannels remains a major
    challenge because a detailed understanding of the\r\nunderlying light-matter interaction
    is missing. Here, we show the coherent\r\nmanipulation of single photons generated
    on-demand from a semiconductor quantum\r\ndot using a rubidium vapor quantum memory,
    forming a hybrid quantum network. We\r\ndemonstrate the engineering of the photons'
    temporal wave function using\r\nfour-level atoms and the creation of a new type
    of electromagnetic induced\r\ntransparency for quantum dot photons on resonance
    with rubidium transitions.\r\nGiven the short lifetime of our quantum dot transition
    the observed dynamics\r\ncannot be explained in the established steady-state picture.
    Our results play a\r\npivotal role in understanding quantum light-matter interactions
    at short time\r\nscales. These findings demonstrate a fundamental active node
    to construct\r\nfuture large-scale hybrid quantum networks."
