ITPAR: A cheap, light, compact source for QKD based on intraparticle entanglement in an integrated photonic circuit (2018-2021)
The aim of this project is to develop the theory, validate the principles, design the optical system and demonstrate a quantum key distribution optical link based on the innovative concept of intra-particle entanglement. An integrated source of a quantum key in a silicon chip will be fabricated and inserted into an optical fiber communications system to demonstrate the feasibility of the concept. The innovation is both on the conceptual aspect of using a single particle for quantum key distribution, on the use of an incoherent light source to generate the entangled state as well as demonstrating quantum key distribution using a single particle based intra-particle entanglement.
