India has made a significant stride in the quantum communication field, marking a potential shift towards real-time applications in quantum cyber security, as reported by the defense ministry. They announced that a successful demonstration of free-space quantum secure communication using quantum entanglement was achieved over a distance exceeding one kilometer, utilising a free-space optical link established on the IIT-Delhi campus. With this achievement, officials noted that India has entered a "new quantum era." Defense Minister Rajnath Singh expressed his congratulations to both the DRDO and IIT-Delhi for this groundbreaking accomplishment. He remarked that this development signifies a new phase in secure communication that could prove to be a "game-changer" in future warfare.
