Project Overview

This project is intended to provide the modelling and simulation methodology for evaluation of quantum channel (single and entangled photon) with atmospheric effects for free space application. It analyzes the various QKD protocols such as BB84, decoy state, E91, SARG04 etc.required for establishing secure communication. It is expected to bring out systematic polarization analysis for satellite based QKD protocols and change in polarization states due to satellite motion, payload optics and other atmospheric parameters. The simulation and analysis is to be carried out for QKD scenarios in LEO and GEO orbits, link budget analysis in terms of power and quantum key rate is to be performed. Simulation and analysis for MIMO system modelling for quantum communication system is also a part of the project.

Achievements

The project being undertaken by ISRO in collaboration with academia is directly or indirectly beneficial to the society.
