IIT-Delhi researchers achieve breakthrough in quantum communication

IIT-Delhi researchers have achieved an experimental breakthrough on secure quantum communication up to a distance of 380 kilometres in standard telecom fiber with a very low error rate. This is said to be helpful in securing financial transactions and secret codes. The results of the research have also been published in the “Nature Scientific Reports” journal.

This long secure length is said to be the highest achieved so far, not only in India but globally, for the Differential Phase Shift (DPS) QKD protocol, according to officials.

“Such low quantum bit error rate (QBER) makes the quantum communication resistance to collective and individual attacks and implementable for various applications, such as securing financial transactions,
