InP-based CV-QKD PIC Transmitter

Abstract: An InP-based photonic integrated circuit (PIC) transmitter for pulsed Gaussian-modulated coherent-state (GMCS) CV-QKD protocol is presented and characterized. Results show potential asymptotic secret key rates of 0.4 Mbps at 11 km, and up to 2.3 Mbps in back-to-back configuration.

“…Among alternative QKD protocols and implementations, continuous variable QKD (CV-QKD) is a promising candidate for facilitating the integration of this technology into the network infrastructure, coexisting with conventional telecommunication technologies. In fact, it allows implementations adopting optical coherent technologies also using commercial off-the-shelf (COTS) components and photonic integrated circuits, for a sustainable development of quantum secure communications [5], [6]. Finally, software defined networking (SDN) further accelerates the adoption of QKD technology by the telecom sector, as well as its integration in the already deployed optical infrastructure and flexible advanced features/functionalities in support of secure 6G networks [7].…”
