Unlike fibre-based quantum communication, free-space QKD transmits quantum signals through the atmosphere using optical systems. Such links are important for locations where laying dedicated fibre may be difficult and are also relevant to the development of future ground-to-air and satellite quantum communication networks.
According to the Indian Navy, the visit provided the Russian delegation with an opportunity to study India’s naval training framework, infrastructure and instructional facilities while discussing ways to expand maritime cooperation and institutional engagement.
Union Commerce and Industry Minister Piyush Goyal has said that India’s existing and upcoming trade agreements could eventually provide preferential access to around 75 per cent of global trade, giving Indian exporters broader access to major international markets.
Ayurveda describes digestion through the concept of Jatharagni, the digestive fire responsible for transforming food into usable nourishment. A meal may contain high-quality ingredients, but Ayurveda maintains that its value depends greatly on whether the body can digest and assimilate it properly.
When Portland clinker reacts with water, it produces compounds responsible for strength as well as calcium hydroxide. The reactive silica and alumina in calcined clay then react with this calcium hydroxide to form additional cementitious products.
The 1,000-kilometre network was demonstrated using indigenous technology developed by QNu Labs, an Indian company working on quantum-safe cybersecurity and quantum communication systems.
This landscape is fundamentally shaped by the Brahmaputra and its many tributaries. Broad floodplains, river islands, wetlands, forests and surrounding hills created an environment very different from the drier plains of the upper Ganga-Yamuna region. Communication naturally followed the great river and the corridors formed between the valley and the surrounding mountains.
Speaking at the Valdai Forum, Putin said Modi shows sustained interest in a peaceful resolution and continues to discuss possible pathways towards ending the conflict. Akashvani News reported the remarks on October 2, 2026.
EON is developing compact optical payloads, while Dhruva is building the satellite platforms and mission infrastructure needed to carry such technologies into orbit.
TAPAS-1 was launched aboard Dhruva Space’s LEAP-2 satellite platform on SpaceX’s Transporter-18 rideshare mission from Vandenberg Space Force Base in California on October 1, 2026. SatLeo Labs subsequently confirmed the payload’s successful orbital deployment.
