Securing the World’s Data in the Quantum Era.
Quantumspace offers affordable and scalable solutions in quantum key distribution, optical laser communication and post-quantum cryptography, securing networks on Earth and in orbit to ensure long-term data security for governments and enterprises.
Why
Quantum computers are arriving faster than expected, putting today’s communications at risk. Satellite and terrestrial networks still exchange encryption keys over open channels, allowing attackers to capture traffic now and decrypt it later when quantum machines mature. As global satellite constellations and data volumes grow, so does the window for compromise.
The answer
Quantumspace protects these networks end-to-end. We combine quantum key distribution across fibre and space, high-bandwidth optical laser communication, and satellite-ready post-quantum cryptography to deliver security that is both physically hard to intercept and mathematically resistant to future quantum attacks. This keeps government, enterprise and critical infrastructure data safe for decades.
What we're building
SATQKD
Compact transmitter module that adds quantum key distribution to any satellite for fast, low-cost deployment.
Optical Ground Station
Precision laser station that handles quantum key exchange and data downlink, keeping satellites simple and costs low.
Laser Communication
Next generation laser downlink and uplink providing high-speed data delivery between space and Earth.
PQC-SAT
Post-quantum cryptography module that hardens classical satellite links.
Use cases
Government & defense backbones
Central banks, exchanges, payment rails
Telco backhaul and data-center interconnects
Cloud/regulator-driven high-assurance networks
Our Vision
Quantumspace began with a simple idea: free space links from ground to satellite delivering keys guaranteed by physics. We aim to build a quantum secure layer that India and the world can deploy quickly and rely on for decades.
From today's secure links to a global quantum internet.
Today
Space→Ground Secure Links
Plug-and-play modules and Quantum Ground Stations for immediate satellite-to-ground security.
Near Term
Commercial Ground Connectivity
Scaling with commercial OGS networks and mission control for end-to-end encrypted space missions.
Future
Global Quantum Internet
Quantum repeaters, entanglement generators, and positioning constellations enabling worldwide quantum-secure networking.
Roadmap
