Bengaluru: The Ministry of Science & Technology has announced that a team of Indian scientists has developed a user-friendly method for generating unpredictable random numbers. The method is essential for developing stronger quantum data encryption and the provision of robust cybersecurity. The breakthrough represents a significant advancement in the field of quantum cryptography.
Quantum cryptography, or quantum encryption involves various cybersecurity methods for encrypting and transmitting secure data. It is founded on the naturally occurring and immutable laws of quantum mechanics. The Raman Research Institute, Bengaluru, an autonomous institute of the Department of Science and Technology (DST), conducted a photonic experiment to illustrate a violation of the Leggett Garg Inequalities (LGI). It serves as a diagnostic test for the “quantumness” of a system in a manner that is free of loopholes.
The team conducted extensive research in collaboration with researchers from the Indian Institute of Science (IISc), Bengaluru, IISER-Thiruvananthapuram, and the Bose Institute, Kolkata to exploit this LGI violation in a fully unexplored domain.
