Indian Scientists Establish Secure Quantum Communication
In a groundbreaking achievement, Indian scientists have successfully demonstrated quantum entanglement-based free-space secure communication over a distance of over one kilometre via an optical link. This experiment, conducted jointly by the Defence Research and Development Organisation (DRDO) and the Indian Institute of Technology (IIT) Delhi, marks a significant milestone in the field of quantum communication.
The achievement is a testament to India’s growing capabilities in quantum technology, which has the potential to revolutionize the way we communicate. Quantum communication is a method of exchanging information between two parties in a way that is secure from eavesdropping. This is because quantum mechanics allows for the creation of entangled particles that can be used to encode and decode messages.
The experiment involved using a technique called quantum key distribution (QKD), which uses entangled photons to encode and decode messages. The entangled photons were transmitted through free space, using an optical link, over a distance of over one kilometre. The receiving end of the link was equipped with a sensitive detector that could detect the presence of the entangled photons.
The team of scientists was able to achieve a secure key rate of 240 bits/second with an error rate of less than 7%. This means that the system was able to transmit secret messages with a high degree of accuracy and security. The experiment was conducted in a controlled environment, with the team taking care to minimize any potential sources of error or interference.
The achievement of secure quantum communication over long distances has significant implications for various fields, including defence and finance. In the field of defence, quantum communication can be used to secure military communications, ensuring that sensitive information remains confidential. In the field of finance, quantum communication can be used to secure financial transactions, eliminating the risk of theft or tampering.
The Defence Minister of India, Rajnath Singh, has hailed the achievement as a “game changer” in future warfare. The Minister stated that the development of quantum communication technology will provide India with a significant advantage in the field of military communications, enabling the country to secure its communications and maintain its strategic superiority.
The achievement of Indian scientists in establishing secure quantum communication is a significant step forward in the field of quantum technology. It demonstrates India’s growing capabilities in this area and its potential to contribute to the global development of quantum communication technology. The experiment is also a testament to the successful collaboration between the DRDO and IIT Delhi, and serves as a model for future collaborations in the field of quantum technology.
