"faster, fault-tolerant, capable of handling complex problems, scalable, resource-efficient using high-dimensional spatial encoding generating large cluster states... encoding multiple qubits within each photon through spatial encoding... cluster states with >9 qubits at 100 Hz... substantially reduces computation time by enabling instantaneous feedforward between qubits encoded within the same photon... quantum computing through photonics"
