India is steadily advancing its quantum technology capabilities, positioning it as a key enabler of next-generation defence systems. Backed by the ₹6,003 crore National Quantum Mission (NQM), launched in 2023, the country aims to build quantum-secure communication networks, navigation systems that function without GPS, and advanced sensors.
Quantum technology promises unprecedented computing speed and unhackable communication, making it a vital tool in modern military strategy. Startups like Hyderabad-based Quantum AI are developing Quantum Key Distribution (QKD), a secure method of communication using quantum principles. Its Centre of Excellence, Qulabs, is already working with government institutions like DRDO and NPCI.
Another firm, QuBeats, recently won the ADITI 2.0 Defence Challenge and is developing a Quantum Positioning System (QPS) for the Indian Navy, designed to navigate GPS-denied zones such as deep seas or bunkers using atomic-level magnetic field detection.
Despite these breakthroughs, the ecosystem faces funding and scalability challenges. Though the NQM was approved with a multi-crore budget, only ₹17 crore has been disbursed so far. In comparison, China has reportedly invested $14 billion in quantum technology.
Beyond defence, companies like QpiAI are exploring commercial applications of quantum-powered AI in sectors like healthcare, space, and automation. Founder Nagendra Nagaraja says their systems are already in use in global projects across the US, France, and Saudi Arabia.
India’s progress is visible. In June 2025, IIT Delhi successfully demonstrated quantum entanglement-based communication over a 1 km distance, hailed by Defence Minister Rajnath Singh as a “landmark achievement.” However, commercialisation and leadership in product development remain key hurdles on the road ahead.
