QSCALE

Enabling technologies for the industrialization of NV center-based sensors

To make quantum sensor technology available for commercial use, advances in miniaturization and integration are necessary for a successful commercial exploitation. The QSCALE project is specifically focusing on essential enabling technologies for NV center-based sensors, which will play a central role in industrial use and in increasing the scalability of this sensor type. In addition to microelectronic and photonic integration as central tools for the miniaturization and to increase energy efficiency, the focus is on questions of scalable manufacturing of the base material, as well as, for the first time, investigations into the reliability of the assembly and interconnection technology of quantum sensors.

Scalability of sensor technology through microelectronic and photonic integration

The microelectronic and photonic integration of NV-center-based sensors pursued in the QSCALE project represents one of the central enabling technologies to increase the scalability of a sensor technology. This bears immense savings potential of the size as well as the power consumption of the sensor. In combination with the scalable fabrication of the sensor output material as well as particular investigations regarding the reliability of micro hybrid packaging for quantum sensors, the QSCALE project lays the scientific and technical foundations for a future use of NV-center-based sensors. For this purpose, sensors in moderate to high quantities and moderate to low unit costs are required.
