Measurement of single NV centers inside a solid immersion lens at mK temperature — •Amer Hasecic, Ioannis Karapatzakis, Marcel Schrodin, Rainer Kraft, and Wolfgang Wernsdorfer — Physikalisches Institut, Karlsruher Institut für Technologie, Karlsruhe, Deutschland

A solid immersion lens (SIL) prevents refraction on a diamond-air surface and therefore increases the collection efficiency of detected photons [1]. SILs are nanofabricated by removing bulk material via focused ion beam technique. Here, we rely on accelerated gallium ions. The photon collection from single Nitrogen-Vacancy (NV) centers inside a solid immersion lens in bulk diamond is examined at mK temperatures. We aim to improve readout times for electron spin and nuclear spin states with the later being a promising system in quantum computing [2].
