  bibo_abstract:
  - "Beamsplitters represent fundamental components in both classical and quantum
    optical systems, enabling the distribution of light, as well as the generation
    of interference, superposition, and entanglement. However, optical networks constructed
    from conventional bulk 2 × 2-beamsplitters encounter inherent scalability issues,
    as the number of required beamsplitters scales quadratically with the number of
    optical modes for a fully connected network. Metasurfaces offer a promising route
    to\r\novercome these constraints. By manipulating light at the wavelength scale,
    compact optical components with advanced functionalities can be constructed, which
    address several modes simultaneously. In this work, we design and experimentally
    utilize a metasurface as a multiport beamsplitter. Furthermore, we realized a
    multimode interferometer composed of two cascaded metasurfaces. We characterize
    the individual and cascaded metasurfaces by using classical light, showing controllable
    splitting ratios through tunable phase relations. We then expand the approach
    to quantum light, employing single photons to demonstrate second- and third-order
    photon correlations as well as single photon interference across multiple spatial
    paths. These results establish metasurface-based multiport beamsplitters as a
    scalable and reconfigurable platform bridging classical and quantum photonics.
