Perfect secrecy cryptography in photonic chips

We are very happy to share our new paper where we demonstrate that it is possible to create a perfect secrecy cryptographic protocol in classical channels. The system uses time varying integrated chips based on silicon on insulator technology and implements a working version of the One Time Pad protocol. The work was the result of the collaboration between our group, King Abdullah University of Science and Technology (KAUST) and the Center for Unconventional Processes of Sciences (CUP Sciences).
