The Defence Research and Development Organisation (DRDO) and its associated labs, like the Naval Physical and Oceanographic Laboratory (NPOL), are responsible for the development of 'Varunastra'.

'Varunastra' is a heavyweight torpedo designed for anti-submarine warfare, capable of being launched from surface ships.

Counter-terrorism operations, including hostage rescue, counter-insurgency, and other unconventional warfare scenarios, are central to the 'Vajra Prahar' exercise.

The Indian Army's Para Special Forces are the primary participants from the Indian side in the 'Vajra Prahar' exercise, focusing on counter-terrorism and special operations.

The 2026 edition of Vajra Prahar was indeed the 15th edition and was held in Rajasthan, marking a significant milestone in bilateral defense cooperation.

Stable qubits are the fundamental building blocks of quantum computers. Enhancing their stability is essential for creating quantum computers that are reliable, scalable, and capable of performing complex computations.

Quantum qubits are highly susceptible to environmental noise, leading to decoherence and instability, which is a major hurdle in building reliable quantum computers. The IISc breakthrough focuses on enhancing qubit stability.

Researchers at the Indian Institute of Science (IISc), Bengaluru, have made a significant breakthrough in improving the stability of quantum qubits.

Ethical AI frameworks typically emphasize principles like fairness, transparency, accountability, and human oversight to ensure AI systems are developed and used responsibly.

The framework is designed to guide the responsible and ethical development, deployment, and use of AI systems, addressing potential risks and promoting trust.
