We describe a method for scalable quantum computing using isolated matter qubits and photonic messenger qubits. We employ graph state quantum computation in which the entangling operation is probabilistic. The entangling operation is extremely robust under photon loss and interferometric instability. In addition, this scheme allows for arbitrary complex qubit-based quantum communication.
