- Title: Quantum nonlinear metasurfaces from dual arrays of ultracold atoms
- Authors: Simon Panyella Pedersen, Lida Zhang, Thomas Pohl
- Abstract summary: We show how the coupling of light to more than a single atomic array can expand perspectives into the domain of quantum nonlinear optics.
The combination of two arrays is found to induce strong photon-photon interactions that can convert an incoming classical beam into highly antibunched light.
Such quantum metasurfaces open up new possibilities for coherently generating and manipulating nonclassical light.

- Abstract: Atoms in a sub-wavelength lattices have remarkable optical properties that
have become of high scientific and technological significance. Here, we show
how the coupling of light to more than a single atomic array can expand these
perspectives into the domain of quantum nonlinear optics. While a single array
transmits and reflects light in a largely linear fashion, the combination of
two arrays is found to induce strong photon-photon interactions that can
convert an incoming classical beam into highly antibunched light. Such quantum
metasurfaces open up new possibilities for coherently generating and
manipulating nonclassical light, from optical quantum information processing to
exploring quantum many-body phenomena in two-dimensional systems of strongly
interacting photons.
