However, despite this promise, in order to realise quantum-networking applications the intrinsic, optical, coherence of the SnV is yet to be shown through Hong-Ou-Mandel (HOM) spectroscopy. In this work, we report on the excited state coherence of the SnV and show that the T2 = 2T1 limit is easily reached given simple Hahn-Echo rephasing protocols. This result further highlights that the SnV is a promising candidate for quantum-networking applications as the maximum achievable HOM visibility is not intrinsically limited. Furthermore, we describe steps towards measuring the HOM visibility to confirm these findings. As such, these preliminary results highlight that the SnV is a realistic platform on which to build photonic cluster states, and similar photonics-based quantum resources, for high fidelity, error-tolerant, quantum communication.
