The overarching goal of the PINTOS innovation consortium is to increase the security of encrypted data through the use of novel, integrated quantum optical systems. To achieve this goal, the project partners are further developing existing laboratory-scale solutions so that suitable production technologies will enable the subsequent industrial-scale manufacturing of these systems. Quantum optical systems consist of individual components such as quantum light sources, manipulation elements, and micro-optical light coupling structures, as well as the necessary upstream and downstream fiber optic components that serve as an interface to the fiber optic infrastructure.
The innovative core of the project lies in the integration of the optical components necessary for quantum encryption onto photonic platforms, so-called Photonic Integrated Circuits (PICs). The goal of the cPINTOS sub-project is the development of photonic gallium nitride systems for quantum communication. The quality of the materials used is crucial. Optical losses in layers and photonic units made of gallium nitride (GaN) and aluminum gallium nitride (AlGaN) are being investigated and optimized.
This sub-project thus makes a significant contribution to the overall goal of the PINTOS consortium: to advance novel integrated quantum technologies toward industrial application and production.
This project is funded by the European Social Fund Plus / European Regional Development Fund.
