This demonstration could enable on-chip generation of photonic cluster states for measurement-based quantum computing within two years.
Multi-qubit state generation on a silicon platform suggests a path to scaling through established semiconductor manufacturing. If the demonstrated state quality can be maintained with larger numbers of qubits, the near-term step of creating small cluster states on a single chip becomes feasible.
