Fusion of deterministically generated photonic graph states.

ABSTRACT: Entanglement has evolved from an enigmatic concept of quantum physics to a key ingredient of quantum technology. It explains correlations between measurement outcomes that contradict classical physics and has been widely explored with small sets of individual qubits. Multi-partite entangled states build up in gate-based quantum-computing protocols and-from a broader perspective-were proposed as the main resource for measurement-based quantum-information processing^1,2. The latter requires the ex-ante generation of a multi-qubit entangled state described by a graph^3-6. Small graph states such as Bell or linear cluster states have been produced with photons^7-16, but the proposed quantum-computing and quantum-networking applications require fusion of such state
