Advancements in quantum computing such as Longer Qubit Coherence (imparting stability), Enhanced Qubit Control and Fidelity (increasing accuracy) & Progress in Error Correction (E.g. Google’s Willow Chip with a self-checking mechanism)  are redefining national security priorities across multiple domains. 

• Recently, NITI Frontier Tech Hub has been established by NITI Aayog as a Frontier Tech Action Tank to accelerate India’s transition into a Frontier Tech Nation.

Role of Quantum Computing in National Security

• Cryptography and Cybersecurity: E.g. Fault-tolerant quantum computers can break public-key encryption algorithms rendering internet security, online banking & communications obsolete. 
• Intelligence Gathering: Complex and vast data processing can lead to increased signal intelligence, unprecedented interception and counterintelligence operations.
• Military Applications: Quantum algorithms can optimize logistics, resource allocation, and battlefield strategy. E.g. Quantum-enabled AI (Quantum AI) can power autonomous military drones and robotic systems.
• Quantum Geopolitics: Early breakthroughs and competition will shape future global power.
