Project Will Build Demonstrators for Transmitting and Receiving Qubits and Focus on Integrating the Technology in a Unique Platform to Address Quantum Computing Applications.
Almost daily, we read about breaches of standard cryptography protocols, with major financial-loss and security-risk implications, and the threat to critical infrastructure, such as power-supply systems," said Ségolène Olivier, R&D project leader at CEA-Leti and coordinator of this project. With the future advent of quantum computers, the risk will drastically increase as current encryption algorithms will not be safe anymore. Quantum cryptography is the solution to this problem as it is not vulnerable to computing power.
Noting that a quantum system based on single-photon qubits must ensure there is minimal propagation loss of photons to be reliable, Olivier said CEA-Leti's silicon photonics platform has achieved a world-record of low-loss silicon and ultralow-loss silicon-nitride waveguides. "Propagation losses in waveguides directly impact the data rate and reach of quantum communications links, that's why it is so important to build ultralow-loss components and circuits,"she said.
Carnot's long and fruitful scientific relationship with CEA-Leti has helped bring many innovative solutions and products to companies and consumers in Europe and around the world," said Susanna Bonnetier, vice president of the Carnot network. "Its silicon-photonics platform is a very promising platform for developing quantum-communication links that will extend this legacy by protecting highly sensitive corporate, government and personal information."
