Query: Experimental Realization of a Four-Photon Seven-Qubit Graph State for
  One-Way Quantum Computation   We propose and demonstrate the scaling up of photonic graph state through
path qubit fusion. Two path qubits from separate two-photon four-qubit states
are fused to generate a two-dimensional seven-qubit graph state composed of
polarization and path qubits. Genuine seven-qubit entanglement is verified by
evaluating the witness operator. Six qubits from the graph state are used to
execute the general two-qubit Deutsch-Jozsa algorithm with a success
probability greater than 90%.
