India's Department of Space, through ISRO, is developing its first quantum communication satellite, part of the National Quantum Mission (NQM). The mission aims to establish secure quantum communications over distances of up to 2000 kilometers, employing satellite-based quantum key distribution (QKD) to ensure un-hackable data links for national security.

Approved in April 2023 with a budget of ₹6,003.65 crore from 2023-24 to 2030-31, the NQM prioritizes quantum technologies, including communication. The flagship satellite, named SAQTI, is expected to launch between 2025 and 2026.

The project includes collaborations with institutions like the Raman Research Institute and builds on previous ground-based trials. India is developing infrastructure for quantum communication networks, with efforts towards post-quantum cryptography to enhance national resilience against cyber threats by 2030.
