title = "Interferometer for phase-stabilization of quantum nodes using SIL-based color centers",
abstract = "Many quantum entanglement generation protocols require phase stabilization between the nodes. For color centers that are embedded in a solid immersion lens (SIL) often a reflection from the SIL{\textquoteright}s surface is input to an interferometer where it is mixed with a reference beam. However, the beam reflected beam by the SIL does not travel colinear with the photons that are emitted by the color center, which ultimately leads to a reduction of the interferometer{\textquoteright}s signal-to-noise ratio (SNR). Additionally, imperfections of the SIL surface introduce aberrations into the reflected light, thereby further reducing the SNR. Through several design-iterations and extensive experience realizing phase stabilization on many different SIL{\textquoteright}s we have come to an approach that significantly improves the SNR and enhances the operability of the quantum node. In this paper we report on our optical design and provide useful guidelines for the operation thereof.",
