"highly scalable, maps classic optic states (instead of fragile quantum sources) into quantum-equivalent computational spaces for processing complex information without complex cryogenic overhead... combines light's polarization, spatial structure, natural photon-number fluctuations with photon-number-resolving detectors, extracting rich multiphoton quantum behavior... accesses multiparticle quantum dynamics of up to 40 photons without hyper-precise control... light performs math transformations"
