"stonger photonic interaction quantum computing, room temperature, minimal decoherence, near-deterministically generated entangled clusters validating success without perturbing target state... 6 photons injected into 10-mode passive interferometer... InAs/GaAs quantum dot single-photon source, interferometer 50% efficiency... specific unitary transformation, output state across ports 1-6 dual-rail... fault-tolerant photonic quantum computers... future: multiple 3-GHZ resource states amalgamated using 8 photons"
