Defence Research and Development Organisation (DRDO) inaugurated the Quantum Technology Research Centre (QTRC).

About

  • Aim: To strengthen indigenous quantum capabilities for strategic and defence applications.
  • QRTC is equipped with state-of-the-art experimental set-ups designed to propel research and development in critical quantum domains. 
  • The key capabilities of this centre include:

  • Characterisation of  Vertical-Cavity Surface-Emitting Lasers and Distributed Feedback Lasers; 
  • Test-beds for evaluating single-photon sources; 
  • Set-up for characterisation of Micro Fabricated Alkali Vapor Cell; 
  • Experimental platforms for developing and validating Quantum Key Distribution techniques to enable ultra-secure communication and safeguard national security in the post-quantum era, spearheaded by Scientific Analysis Group (SAG), DRDO.
  • QTRC also focuses on Foundational Technologies 

    Foundational Technologies (led by SSPL):

  • Ultra-Small Atomic Clock based on Coherent Population Trapping for precise timekeeping in GNSS-denied environments.
  • Atomic Magnetometer using optically pumped magnetometry for ultra-sensitive magnetic field detection.
  • Research on cutting-edge solid-state quantum devices and materials.
  • Quantum Technology

  • Quantum technology is a rapidly advancing field that leverages the principles of quantum mechanics to develop new technologies with unprecedented capabilities.
  • Quantum mechanics is the branch of physics that studies the behavior of particles at the quantum level, where classical physics no longer applies. 
  • Quantum technology harnesses the unique properties of quantum systems, such as superposition and entanglement, to perform tasks that were previously thought impossible or significantly enhance existing capabilities.
  • Four domains of quantum technologies:

  • Quantum communication: It applies the properties of quantum physics to provide better security and improved long-distance communications.
  • Quantum simulation: It refers to the use of a quantum system to simulate the behavior of another quantum system. 
  • Quantum computation: It is a field of computing that utilizes the principles of quantum mechanics to perform certain types of calculations more efficiently than classical computers.
  • Quantum sensing and metrology: It leverages the principles of quantum mechanics to achieve highly precise measurements.
  • National Quantum Mission (NQM)

  • The government approved the NQM in 2023 from 2023-24 to 2030-31.
  • Aim: To seed, nurture and scale up scientific and industrial R&D and create a vibrant & innovative ecosystem in Quantum Technology (QT).
  • This will accelerate QT led economic growth, nurture the ecosystem in the country and make India one of the leading nations in the development of Quantum Technologies & Applications (QTA).
  • Objectives: The Mission objectives include developing intermediate-scale quantum computers with 50-1000 physical qubits in 8 years in various platforms like superconducting and photonic technology.
  • Satellite-based secure quantum communications between ground stations over a range of 2000 kilometers within India, long-distance secure quantum communications with other countries, inter-city quantum key distribution over 2000 km as well as multi-node Quantum networks with quantum memories.
  • Developing magnetometers with high sensitivity in atomic systems and Atomic Clocks for precision timing, communications, and navigation. 
  • It will also support the design and synthesis of quantum materials such as superconductors, novel semiconductor structures, and topological materials for the fabrication of quantum devices. 
  • Single photon sources/detectors, and entangled photon sources will also be developed for quantum communications, sensing, and metrological applications.
  • Implementation:Four Thematic Hubs (T-Hubs) have been set up, bringing together 14 Technical Groups across 17 states and 2 Union Territories.
  • Indian Institute of Science (IISc) Bengaluru
  • Indian Institute of Technology (IIT), Madras in association with the Centre for Development of Telematics, New Delhi
  • Indian Institute of Technology (IIT), Bombay
  • Indian Institute of Technology (IIT), Delhi.
