Electrical readout of NV⁻ centres — •Manuel Schiefer, Julius Röwe, David Vogl, and Martin S. Brandt — Walter Schottky Institut and Physik-Department, Technische Universität München, Garching, Germany

Recently, the readout of the spin state of NV⁻ centres in diamond has been demonstrated monitoring conductivity rather than luminescence. This approach carries the potential to significantly simplify the realisation of integrated devices for, e.g., quantum information processing or metrology. In this contribution, we study the elementary processes leading to the photoionisation of the NV⁻ centre to further understand and improve the electrical spin readout.
