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