India has taken a major leap in defence and cyber security by successfully demonstrating free-space quantum secure communication using quantum entanglement, Defence Minister Rajnath Singh said on Monday.<\/p>\n
The Union Minister said that the country has entered a new quantum era of secure communication, which will prove to be a game changer in future warfare.<\/p>\n
The breakthrough was achieved by the DRDO-Industry-Academia Centre of Excellence (DIA-CoE) at IIT Delhi.<\/p>\n
The demonstration involved transmitting quantum entangled particles over a free-space optical link across a distance of more than one kilometre within the IIT Delhi campus. <\/p>\n
The experiment achieved a secure key rate of nearly 240 bits per second, with a quantum bit error rate of less than 7 per cent. <\/p>\n
According to experts, this technology enables real-time applications in quantum cyber security, including long-distance Quantum Key Distribution (QKD), future quantum networks and the quantum internet.<\/p>\n
Quantum entanglement-based communication provides stronger security than traditional methods.<\/p>\n
Even if the communication devices are compromised, entangled photons reveal any attempts at interception by disrupting their quantum state.<\/p>\n
This makes the encryption virtually unbreakable and highly useful in sectors like defence, finance, telecommunications and other strategic areas. <\/p>\n
A key benefit of this new method is that it eliminates the need for laying optical fibres, which is costly and difficult in remote or densely populated areas. <\/p>\n
The project, titled ‘Design and development of photonic technologies for free space QKD,” was sanctioned by the Directorate of Futuristic Technology Management (DFTM), DRDO.<\/p>\n
The demonstration was led by Professor Bhaskar Kanseri’s research group and witnessed by top officials including DRDO DG (MED, COS & CS), Director SAG, Director DFTM, Dean (R&D) IIT Delhi, and other scientists.<\/p>\n
Congratulating the team, DRDO Chairman Dr Samir V Kamat and IIT Delhi Director Prof Rangan Banerjee called it a significant milestone in India’s technological advancement. <\/p>\n
This is not the first success for the team. In 2022, DRDO and IIT Delhi demonstrated India’s first intercity quantum communication link between Vindhyachal and Prayagraj using underground optical fibre. <\/p>\n
In 2024, they successfully distributed quantum keys over a 100 km spool of telecom-grade optical fibre. <\/p>\n
These achievements come under DRDO’s DIA-CoEs initiative, which has set up 15 Centres of Excellence at leading institutions like IITs and IISc to develop cutting-edge defence technologies.<\/p>\n","protected":false},"excerpt":{"rendered":"
