Quantum Hub Thüringen

Research and implementation strategy on quantum technology from Thüringen

For quantum technology from Thüringen, Germany, IMMS is researching CMOS-based single-photon detectors.

Quantum technology is considered to be a key technology of the future. It enables the development of highly efficient technology that can far surpass the performance of conventional systems. By controlling individual quanta, i.e. the smallest light and energy components, disruptive applications are made possible, for example in the field of data processing (quantum computers), communications (tap-proof communications) and metrology (quantum imaging, quantum sensor technology).

IMMS is researching the use of single photon detectors (SPAD), which are manufactured in a standard semiconductor technology (CMOS). They are used to convert single photons into electrical signals and allow operation at room temperature without large and complex cooling systems. Statistical evaluation is required to interpret the sensor signals, which is performed by a programmable logic device (FPGA). In addition, the integration of such an optical sensor element in conjunction with the necessary evaluation electronics in a microchip is also being targeted.
