*************************************************************************
In a groundbreaking experiment, researchers have successfully demonstrated quantum secure communication over a free-space optical link for a distance of 1 kilometer. This achievement follows ISRO's 2021 demonstration of free-space Quantum Key Distribution (QKD) over a distance of 300 meters. The experiment, part of DRDO's project for developing photonic technologies for free-space QKD, shows great promise in enhancing cyber security and real-time applications of quantum internet. The Quantum Bit Error Rate (QBER) in this experiment remained below 7%, ensuring that the information sent and received remains secure from third-party interception. This marks a major step towards creating highly secure communication channels and strengthens the development of quantum internet technologies.
