Title: Demonstrating space-based quantum key distribution using nano-satellites

Abstract: Quantum key distribution (QKD) is one of the major application areas in which entangled photon-pair sources are used. Satellites carrying quantum source of light as well as the receiver unit to detect the photons emitted from the source are essential for establishing space-to-ground quantum communication. We have developed entanglement-based QKD systems with Cubesat standards, which could be one of the vital elements for practical realization of global quantum network. Along with the source, we build a receiver unit in an optical ground station to detect the photons sent from satellite, which is currently under construction.  In this talk, I will discuss the developmental stages of the small-scale entangled photon-pair source for space-based QKD, and the status updates of the development of receiver units on the ground station in Singapore.
