The performance of modular, networked quantum technologies will be contingent upon the quality of their light-matter interconnects. Solid-state colour centres, and in particular T centres in silicon, offer competitive technological and commercial advantages as the basis for quantum networking and distributed quantum computing. These newly rediscovered silicon defects offer direct telecommunications-band photonic emission, long-lived electron and nuclear spins, and proven integration into industry-standard, CMOS-compatible, silicon-on-insulator (SOI) photonic chips at scale. Here we present recent advances with T centre devices towards high-performance, large-scale distributed quantum technologies based upon T centres in silicon.
