This project represents, to our knowledge, the first US commercialization of doped diamond (eg. PIN) diode-type structures offered with controlled quantum properties, enabled by phosphorous-doped diamond growth. Specifically, Advent Diamond proposes to develop novel doped quantum diamond materials for nitrogen-vacancy (NV) center-based sensors and other quantum technologies. The proposed innovations are: (i) PQuantum Diamond, a new quantum material consisting of a layer of phosphorous-doped diamond with NV centers on a single crystal diamond and (ii) custom diamond growth services, including the growth of PIN layers with beneficial quantum properties, all to enable novel quantum measurement devices. This innovation will be particularly significant to quantum magnetometer designs utilizing electrical readout mechanisms.
