Title: Developing an array of site-controlled pyramidal quantum dots emitting polarization-entangled photons

We present a site-controlled, highly symmetric quantum dot system with a density of at least 15 % of polarization-entangled photon emitters. Fidelity values of the entangled state as high as 0.721±0.043 were found.
