ams OSRAM, Fraunhofer IIS, and TOPTICA present joint project DigiQuant for digitalization and miniaturization of laser diode technology for quantum and terahertz applications.

Diode-laser-based technology is a key enabler for quantum optics. Within the DigiQuant project new laser diodes will be developed at ams OSRAM, which are suitable for hybrid integration of photonic waveguides and digital control electronics at TOPTICA.

In parallel, the miniaturization of electronics in integrated circuits for digitized operation of any material class laser diodes from diverse manufacturers will be investigated with Fraunhofer Institute for Integrated Circuits IIS and TOPTICA. The miniaturized and digitized subsystem will be tested in two different applications, a quantum computer application and in an industrial application to readout a digital code with a hand-held scanner.

Bringing quantum computers to market

These combined developments will enable the implementation of complex laboratory technology in portable and robust devices with high wall plug efficiency for industrial use and help to scale up quantum computers and take them from the basic research stage to market maturity.
