Colour centres in solid-state materials are promising for quantum communication, offering robust optical and spin properties. However, scaling up the experiment from single colour centres to plethora of colour centres on chips remains a significant challenge. Here, we present an approach to fabricating photonic quantum chips with divacancy (VV) centres in silicon carbide (SiC). By utilizing SiC-on-insulator (SiC-OI) substrates, we could establish a robust and industry-compatible design for scalable quantum technologies. Our method integrates VV centres into photonic structures, enabling efficient spin-photon interactions and chip-scale integration. With these chips, our ambition is to perform photonic interference experiments to entangle neighbouring VV centres on a chip.
