Satellite-based Quantum Communication is a method of transmitting information securely using quantum principles via satellites in space. It leverages quantum key distribution (QKD), which allows two parties to share cryptographic keys over long distances with the assurance that any eavesdropping attempt can be detected.
In the age of global mobility, securing communication link between just two places against the threat posed by impending quantum computers does not make a practical sense. It has to be a global network. Although one cannot have a fibre based secure global quantum communication network with the present technology however, it is very much possible to have a worldwide quantum secure communication using satellites with the technological advancements achieved till date. China has already demonstrated a quantum secure link with Europe and Africa using satellite and aims to have a global network by 2027.
