| 内容記述 | Development of quantum devices with indistinguishable photon generation and spin-based quantum information processing is necessary to realize remote quantum applications and networking. However, identification of suitable systems in scalable platforms has not yet been demonstrated. Here, we investigate the silicon vacancy centre in silicon carbide and demonstrate controlled emission of non-distinguishable and distinguishable photons using spin manipulation. On the basis of strong off-resonant excitation and collecting zero-phonon line photons, we show a two-photon interference contrast close to 90% in Hong-Ou-Mandel type experiments. Further, we exploit the system’s intimate spin-photon relation to spin-control the colour and indistinguishability of consecutively emitted photons. This demonstration provides a deep insight into the system’s spin-phonon-photon physics and underline the potential of the industrially compatible silicon carbide platform for measurement-based entanglement distribution and photonic cluster state generation. | |||||
