Novel single photon sources for new generation of quantum communications

Project Member(s): Aharonovich, I.

Funding or Partner Organisation: Air Force Office of Scientific Research

Start year: 2015

Summary: Securing global information transfer is one of the most urgent goals in our society. While classical encryption algorithms are robust, they are subject to sophisticated eavesdropping and security breaches. This project aims to develop ideal single photon sources that will be used as building blocks for quantum cryptography and quantum key distribution. Several platforms including color centers in diamond and silicon carbide will be investigated. Employing single photon sources will enable encoding the information into individual photons that cannot be cloned or breached, as governed by the fundamental laws of quantum mechanics. The outcomes of the project will establish a new generation of building blocks for communication channels and enable absolutely secured information transfer between distant nodes
