  text: <jats:p>We theoretically investigate strategies for the deterministic creation
    of trains of time-bin entangled photons using an individual quantum emitter described
    by a Λ-type electronic system. We explicitly demonstrate the theoretical generation
    of linear cluster states with substantial numbers of entangled photonic qubits
    in full microscopic numerical simulations. The underlying scheme is based on the
    manipulation of ground state coherences through precise optical driving. One important
    finding is that the most easily accessible quality metrics, the achievable rotation
    fidelities, fall short in assessing the actual quantum correlations of the emitted
    photons in the face of losses. To address this, we explicitly calculate stabilizer
    generator expectation values as a superior gauge for the quantum properties of
    the generated many-photon state. With widespread applicability in other emitter
    and excitation–emission schemes also, our work lays the conceptual foundations
    for an in-depth practical analysis of time-bin entanglement based on full numerical
    simulations with predictive capabilities for realistic systems and setups, including
    losses and imperfections. The specific results shown in the present work illustrate
    that with controlled minimization of losses and realistic system parameters for
    quantum-dot type systems, useful linear cluster states of significant lengths
    can be generated in the calculations, discussing the possibility of scalability
    for quantum information processing endeavors.</jats:p>
