Metropolitan Quantum Key Distribution based on Room Temperature Single Photon Source — •Haoran Zhang — School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore, Singapore

Quantum Key Distribution (QKD) is a cryptographic technology that supports the negotiation and sharing of private keys with unconditional security between authorized parties. As QKD scales to a global level, it must address performance limitations, high costs, and practical security concerns. For the deployment of QKD using single-photon sources (SPSs), existing demonstrations are still limited to operation at cryogenic temperatures. We realized the first demonstration of QKD based on a telecommunication-wavelength SPS operating at room temperature, as well as the first metropolitan-scale SPS-based QKD experiment at room temperature, paving the way for the commercial deployment of SPS-based QKD systems.
