- Abstract summary: We report ultra-long photonic quantum walks across several hundred optical modes, obtained by propagating a light beam through very few closely-stacked liquid-crystal metasurfaces.
With this setup we engineer quantum walks up to 320 discrete steps, far beyond state-of-the-art experiments.

- Abstract: The possibility of fine-tuning the couplings between optical modes is a key
requirement in programmable photonic simulators and quantum computers.
Engineering particle evolutions across large lattices is a challenging task,
which requires sophisticated setups that are often intrinsically lossy. Here we
report ultra-long photonic quantum walks across several hundred optical modes,
obtained by propagating a light beam through very few closely-stacked
liquid-crystal metasurfaces, without any optical amplification. By exploiting
spin-orbit effects, these metasurfaces realize a space-dependent polarization
transformation which mixes circularly polarized optical modes carrying
quantized transverse momentum. With this setup we engineer quantum walks up to
320 discrete steps, far beyond state-of-the-art experiments. To showcase the
potential of this method, we experimentally demonstrate that in the long-time
limit a quantum walk affected by dynamical disorder generates maximal
entanglement between two system partitions. Our platform grants experimental
access to ultra-long unitary evolutions while keeping optical losses constant,
thereby paving the way to massive multi-photon multi-mode quantum simulations.
