Abstract: An architecture for fault-tolerant universal quantum computation is suited for matter qubits, such as donor qubits in silicon, coupled by a network of photonic interconnects. The basic operational building blocks are local measurements and unitaries, plus an entangling measurement of non-local Pauli operators. 3D graph states created by applying deterministic entangling measurements to pairs of qubits in knitting and fusion processes to yield resource states for one way computing. The deterministic entangling measurements are facilitated by configuring the network with active switches to allow single photons to interact with pairs of matter qubits.
