Published on 23 Feb 2025
Quantum technology leverages the principles of quantum mechanics to revolutionize various sectors, offering unprecedented precision, security, and computational power.
Significance of Quantum Technology
Quantum Communication: Secure data transmission using quantum bits (qubits), resistant to eavesdropping.
Example: Quantum Key Distribution (QKD) for encrypted communications.
Quantum Sensing: Precision measurements of forces, fields, and time, enhancing accuracy in navigation and medical imaging.
Example: Quantum sensors in MRI machines for higher resolution imaging.
Quantum Computing: Solves complex problems beyond classical computing capabilities, revolutionizing fields like cryptography and material science.
Example: Google's quantum computer, Sycamore, achieving quantum supremacy.
Quantum Simulation: Simulates materials and reactions at the quantum level, aiding in the discovery of new drugs and materials.
Example: Simulation of chemical reactions for drug development using quantum simulators.
Initiatives by Government of India for Quantum Technology
National Quantum Mission (NQM): Focuses on research and development in quantum technologies to position India as a global leader.
QUEST Initiative: Supports quantum-enabled science and technology for advancements in quantum research.
