The Indian National Space Promotion and Authorization Centre (IN-SPACe) and Bangalore-based deep tech startup QNu Labs have signed a memorandum of understanding (MoU) to create domestic satellite QKD (quantum key distribution) products.

QNu Labs develops next-generation security solutions by harnessing the power of quantum cryptography to address the cybersecurity challenges posed by the classical computing world. The company is disrupting existing security paradigms by accelerating the transition towards deploying Quantum-safe encryptions. 

A major obstacle to building a large-scale quantum secure network is the requirement of repeaters every 100–150 kilometres for terrestrial QKD systems. However, with Satellite QKD capability, the collaboration gives India a chance to lead the future of global quantum communication networks involving a combination of the quantum-satellite constellation, providing intercontinental connectivity.

With the help of ISRO and IN-SPACe, QNu Labs hopes to demonstrate limitless distance satellite QKD-based quantum secure communication through this MoU.

Dr. Prafulla K Jain, Director Programme Management and Authorization, IN-SPACe, Department of Space, said, “For a country like India, with the expansion of the space sector and significant shifts in advanced technologies, especially in network and communication domains, it is very crucial to have a robust ecosystem in place so that we have smooth operations without compromising any sensitive data.” 

ISRO & IN-SPACe will play a crucial role in this mission by providing QNu Labs with payload designs, telemetry, and other related activities. This project will offer secure cryptographic key delivery services to customers for a variety of applications serving the industry, government, and defence sectors, where the security and confidentiality of shared information are essential. 

Formed in 2020, IN-SPACe aims to open up the space sector to private players and provide them with the necessary infrastructure and assistance to enable faster progress in India’s space activities. IN-SPACe is responsible for the promotion, enabling, authorization,

and supervision of various space activities of the Non-Governmental Entities (NGEs) that include building launch vehicles and satellites, offering space-based services, sharing space infrastructure and premises with ISRO, and establishing new space infrastructure and facilities.
