"overcomes optical loss increase as number of modes grow... set of 3 LC metasurfaces simulating quantum processes, such as quantum walk... in theory, can handle as many modes as needed while maintaining constant optical losses... overcomes LC pattern disruption risk, using algorithm creating smooth patterns, incorporating isolated vortices not significantly impacting light propagation... simulated up to 800 optical modes, much more than could be achieved with 1D-setup... scalable quantum simulations/ all-optical AI"
