New light sources for the second quantum revolution
07.11.2022 - The DigiQuant project develops new laser diodes at AMS-Osram, which are suitable for hybrid integration of photonic waveguides and digital control electronics at Toptica.
Diode-laser-based technology is a key enabler for quantum optics. Within the DigiQuant project, the miniaturization of electronics in integrated circuits for digitized operation of any material class laser diodes from diverse manufacturers will also be investigated with the 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.
