    • In a first for India, C-DOT and PRL demonstrated integration of C-DOT’s indigenous Fibre-based Quantum Key Distribution (QKD) system with PRL’s Free Space QKD.
      • Centre for Development of Telematics (C-DOT) is telecom Research and Development arm of Department of Telecommunications.
      • Physical Research Laboratory (PRL) is a research institute under the Department of Space.

     

    • QKD is a technique of quantum communications which enables future-proof security of communication networks using a cryptographic protocol involving components of quantum mechanics. 
      • It enables two parties to produce a shared random secret key known only to them, which can be used to encrypt and decrypt messages
      • Any intervention or tampering in quantum channel gets detected and key distribution can be aborted. 
      • QKD can be deployed through different mediums viz. optical fibre, free space as well as satellite to establish secure communication network.

     

    • Quantum communications is one of the four verticals of Quantum Technology along with Quantum Computing, Quantum Sensors and Quantum Materials.
      • Quantum technology is based on principles of Quantum mechanics such as superimposition, entanglement, tunnelling etc.
      • Its applications are in secure communication, computing, simulation, chemistry, healthcare, cryptography, imaging among others.

     

    Initiative taken for quantum technology in India

    • National Mission on Quantum Technologies and Applications (NM-QTA).
    • Quantum-Enabled Science and Technology (QuEST).
    • Quantum Frontier mission of Prime Minister Science, Technology & Innovation Advisory Council (PM-STIAC).
    • National Mission on Interdisciplinary Cyber-Physical Systems (NM-ICPS).
