Fusion-based quantum computing relies on small entangled resource states that are then fused together probabilistically via linear optical circuits. Here, the authors demonstrate temporal fusion—where resource states generated at different times by the same quantum emitter are fused together—using a spin-photon interface in a quantum dot embedded in a photonic crystal waveguide.
