Quantum-Enhanced Cyber Security: Experimental Computation on Quantum-Encrypted Data
Philip John Walther · 2017
Abstract : The main budget contribution was dedicated to develop and investigate the high-quality processing of polarization-encoded photos usinglaser-written waveguides. The PI developed novel techniques for reducing the photon loss when coupling to waveguide structures as well asnew methods for the characterization of complex waveguide structures. All the within this project developed methods and technologies arenecessary prerequisites for performing experimental quantum computations with quantum-encrypted data. Even though the project finishedbefore such a computation could be demonstrated, it must be it must be emphasized that this project is a success by enabling thechallenging and necessary developments for this ambitious goal. It is worth the mention that the scientific developments of this projectcontributed directly also to two additional peer-reviewed publications: one theory paper in the Journal of Optics and one experimentalpaper in Science Advances.
