We report on the first-time generation of biphotons via spontaneous parametric down- conversion driven by Mie-type resonances in subwavelength metasurfaces. The measured …

We consider a generation of two-particle quantum states in the process of spontaneous parametric down-conversion of light by a dielectric nanoparticle with $\chi^{(2)} $ response …
