GKP qubits are generated using GBS sources. Many GBS outputs are combined at a refinery to boost the overall quality and probability of GKP sources12. Arbitrary cluster states can be synthesized from these states deterministically using a network of beamsplitters23. The need for scalable fabrication of GBS sources is evident for a scalable and high-quality cluster state.
