Abstract
We present a novel nonlinear metasurface featuring reconfigurable symmetry protected bound states in the continuum. It enhances photon-pair generation at non-degenerate photon frequencies via spontaneous parametric down-conversion, opening new opportunities for quantum spectroscopy and sensing.
