Abstract:

The main budget contribution was dedicated to develop and investigate the high-quality processing of polarization-encoded photos using laser-written waveguides. The PI developed novel techniques for reducing the photon loss when coupling to waveguide structures as well as new methods for the characterization of complex waveguide structures. All the within this project developed methods and technologies are necessary prerequisites for performing experimental quantum computations with quantum-encrypted data. Even though the project finished before such a computation could be demonstrated, it must be it must be emphasized that this project is a success by enabling the challenging and necessary developments for this ambitious goal. It is worth the mention that the scientific developments of this project contributed directly also to two additional peer-reviewed publications one theory paper in the Journal of Optics and one experimental paper in Science Advances.
