Résumé : Long-distance interactions are crucial for scaling quantum dot spin qubit devices. Silicon presents a promising platform for these advancements, as it enables the simultaneous integration of photonic circuits and colour centres (such as T-centers), strongly coupled to telecom light, as well as gate-defined SiMOS quantum dot spin qubits. We propose a scheme that leverages T-centers to mediate the interaction between quantum dot spin qubits and optical light. This approach can be extended to achieve either ultra-long-distance entanglement between two quantum dot spins or be adapted for fast and all-optical quantum measurement. Additionally, we estimate fidelities for prepared Bell states under realistic experimental conditions.
