The Defense Research and Development Organization -Industry-Academia Center of Excellence (DIA-CE) in IIT Delhi has shown quantum safe communication with free space by quantum entanglement at a distance of more than one km using an optical connection. Development is considered to be a key breakthrough in cyber security.
Minister of Defense Rajnath Singh congratulated Drdo and Iit-Delhi and described it as a landmark that shows India’s input into the new quantum era of safe communication, “which will be a game converter in the future warfare”.
The IIT-Delhi campus has reached a safe rate of almost 240 bits per second with a quantum bit error of less than 7%. “This Quantum Secure Communication supported by infested entanglements for informed real -time applications in quantum cyber security, including quantum distribution of long distance keys (QKD), the development of quantum networks and future quantum Internet,” the Defense Ministry said.
The Ministry said that, in accordance with the wider objectives of India to progress quantum technologies for national development, the project “The proposal and development of photonical technologies for QKD in the open”, sanctioned by the Futuristic DrDO technology administration, and the demonstration was provided by prof.
“QKD based on quantum entanglement offers several significant advantages over the traditional method of preparation and level of increasing safety and functionality. Although the device is at risk or imperfect, the use of quantum entanglement ensures the safety of the key.
The Ministry said that quantum communication provided fundamentally unbreakable encryption, making it technology with dual use with applications in providing data in strategic sectors such as defense, finance and telecommunications, as well as national security -related communication. “Free-Space QKD eliminates the need to lay optical fibers that can be disturbing and expensive, especially in demanding terrains and dense urban environment,” the ministry said.
Formerly the first Indian intercity quantum communication between Vindhyacal and Prayagraj in 2022, using underground underground dark optical fiber, scientists have shown the scientists together with the team of prof. Bhaskara. In 2024, the team successfully distributed quantum keys using over 100 km of telecommunications optical fiber coil in another project supported by a bunny.
These technologies evolve through DIA-COE, 15 of which were established at leading academic institutions such as IIT, IISC and universities.
