> Abstract: [...] Here we report a photonic ski-jump — a nanoscale waveguide monolithically integrated on a piezoelectric cantilever [...] Finally, by demonstrating uniformity across a 64 ski-jump array, we establish a pathway to achieving greater than one gigaspot resolution at kilohertz rates within a sub-5-cm-diameter footprint, creating a seamless optical pipeline between integrated photonic processors and the free-space world

That could workaround photonic waveguide space constraints; it's lossy to cross photons on a bus because photons do interfere and there's not room for that many layers of fiber in a chip. But still a free space photonic computer doesn't have gates; though there are at least some operators in photon-photon interactions. (It's become unacceptable to post AI generated comments on HN and I'm annoyed at the level of work required to paraphrase and I don't owe anyone my time or my work and I don't want to uncitedly suppose LLM AI-supported research as anything but, and I would just link to the chat but so here's this just: Polaritonic Airy Beam
