CEA-Leti to build quantum-photonics platform
Quantum-photonics project will build demonstrators for transmitting and receiving qubits with the aim of delivering ultra-secure data.

Looking to deliver hack-proof digital communication, CEA-Leti has plans to build a quantum-photonics platform to develop next-generation technologies for key industries that require ultra-secure data transmission. Quantum technology is expected to provide unconditionally safe data encryption required by the finance, health care, energy, telecommunications, defense and other essential industries and sectors.

“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 and coordinator at CEA-Leti.

“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.”

Funded by Carnot, a French multidisciplinary network that pursues R&D which benefits society, the project will build on CEA-Leti's silicon-photonics platform complemented with new quantum characterization equipment for designing, processing and testing quantum-photonic integrated components and circuits. The institute uses photons to build quantum bits, or qubits, which are the best physical means for quantum communications.
