Machine learning improved search for nitrogen-vacancy colour centres with long coherence times — •Ricky-Joe Plate, Jan Thieme, and Kilian Singer — Universität Kassel, Kassel, Germany

Nitrogen-vacancy colour centres are offering promising qubits for room temperature quantum information processing [1]. The quality of the qubits varies over a typical diamond sample and finding colour centres with long coherence times can be a time-consuming process in the lab. Here we present the architecture of a machine learning-based network [2] that allows for an automated search and characterization of optimal colour centres. An open-source implementation based on high-speed c++ code will be presented, that allows easy integration of custom improvements to the code base.
