Abstract
A substrate comprising diamond has NV− centers in a concentration greater than about 0.5 parts per million (ppm). The method for producing this diamond substrate includes providing diamond being doped with nitrogen, irradiating at least a partial surface of the substrate with radiation that creates vacancies in the diamond, and carrying out a second heat treatment of the substrate at a certain temperature. The substrate can be used as a sensor element of a magnetometer or also as a qubit of a quantum computer.
