India Achieves Quantum Communication Milestone
India has made a significant advancement in super-secure communication using tiny particles linked together.
Scientists sent secret information through the air, like a spy-proof phone line, over a distance of 1 kilometer.
If someone tries to listen in, the system knows.
This breakthrough means messages can be sent without cables.
This new technology is a big step forward for keeping important information safe, especially for the military.
India successfully demonstrated free-space quantum secure communication.
The experiment used quantum entanglement over a distance of more than 1 kilometer.
A secure key rate of approximately 240 bits per second was achieved.
The quantum bit error rate was below 7 percent.
The project, led by DRDO and IIT Delhi, advances quantum cybersecurity.
