- Abstract: The scaling barriers currently faced by both quantum networking and quantum
computing technologies ultimately amount to the same core challenge of
distributing high-quality entanglement at scale. In this Perspective, a novel
quantum information processing architecture based on optically active spins in
silicon is proposed that offers a combined single technological platform for
scalable fault-tolerant quantum computing and networking. The architecture is
optimized for overall entanglement distribution and leverages colour centre
spins in silicon (T centres) for their manufacturability, photonic interface,
and high fidelity information processing properties. Silicon nanophotonic
optical circuits allow for photonic links between T centres, which are
networked via telecom-band optical photons in a highly-connected graph. This
high connectivity unlocks the use of low-overhead quantum error correction
codes, significantly accelerating the timeline for modular, scalable
fault-tolerant quantum repeaters and quantum processors.
