Siddarth Koduru Joshi’s research interests include entanglement sources, quantum networks and satellite QKD. He has pioneered multiplexed many-user quantum entanglement networks and worked on their applications beyond just QKD protocols, e.g. through anonymity, digital signatures, and authentication transfer. Siddarth has built the DV source for the SPOQC low-earth-orbit demonstrator, corresponding receivers for the Hub Optical Ground Station and the ground station for OS2-VOLT
