  text: <jats:title>Abstract</jats:title><jats:p>Tailored nanoscale quantum light
    sources, matching the specific needs of use cases, are crucial building blocks
    for photonic quantum technologies. Several different approaches to realize solid-state
    quantum emitters with high performance have been pursued and different concepts
    for energy tuning have been established. However, the properties of the emitted
    photons are always defined by the individual quantum emitter and can therefore
    not be controlled with full flexibility. Here we introduce an all-optical nonlinear
    method to tailor and control the single photon emission. We demonstrate a laser-controlled
    down-conversion process from an excited state of a semiconductor quantum three-level
    system. Based on this concept, we realize energy tuning and polarization control
    of the single photon emission with a control-laser field. Our results mark an
    important step towards tailored single photon emission from a photonic quantum
    system based on quantum optical principles.</jats:p>

  text: Employing the ultrafast control of electronic states of a semiconductor quantum
    dot in a cavity, we introduce an approach to achieve on-demand emission of single
    photons with almost perfect indistinguishability and photon pairs with near ideal
    entanglement. Our scheme is based on optical excitation off resonant to a cavity
    mode followed by ultrafast control of the electronic states using the time-dependent
    quantum-confined Stark effect, which then allows for cavity-resonant emission.
    Our theoretical analysis considers cavity-loss mechanisms, the Stark effect, and
    phonon-induced dephasing, allowing realistic predictions for finite temperatures.

  text: The Kane–Mele model was previously used to describe effective spin–orbit couplings
    (SOCs) in graphene. Here we extend this model and also incorporate curvature effects
    to analyze the combined influence of SOC and curvature on the band structure of
    carbon nanotubes (CNTs). The extended model then reproduces the chirality-dependent
    asymmetric electron-hole splitting for semiconducting CNTs and in the band structure
    for metallic CNTs shows an opening of the band gap and a change of the Fermi wave
    vector with spin. For chiral semiconducting CNTs with large chiral angle we show
    that the spin-splitting configuration of bands near the Fermi energy depends on
    the value of $\text{mod}(2n+m,3)$ .
