Abstract

The necessity for scalable, reliable and reproducible quantum systems is raising in the time for appealing potentialities in application of this technology. On-chip photonic solutions are a leading competitor by combining established classical fabrication technologies, integrated photonics and quantum optical effects. Lithium Niobate on insulator (LNOI) is one of the main contenders for the integration of on-chip functionality. Rare Earth Ions (REI) already proved many different good properties in term of optical and spin features as well as good integration through implantation. In particular, ¹⁷¹Ytterbium showed to have clock transitions in the zero phonon line at zero field which would screen magnetic noise from high spin materials. Here the possibility to create a reconfigurable interferometer on-chip by the employment of fabrication techniques has been showed with the creation of LN structures, interconnecting infrastructure and far field coupling from SU8 resist. Moreover, doping Lithium niobate photonic crystal cavities has been investigated to be employed as switchable single photon sources.
