Study Notes

Quantum Physics Overview

  • Quantum physics examines nature at atomic and subatomic levels, focusing on energy levels.
  • Key concept of Quantization: Energy is absorbed or emitted in discrete packets called quanta.
  • Wave-Particle Duality indicates that particles like electrons display both wave-like and particle-like behaviors.
  • Superposition allows particles to exist in multiple states simultaneously until observed.
  • Entanglement creates a link between particles, where the state of one affects the state of another regardless of distance.

India's National Quantum Mission

  • Official launch by the Government of India aimed at advancing quantum technology.
  • Mission was approved in April 2023 with a budget of Rs. 6003.65 crore, spanning from 2023-24 to 2030-31.
  • Primary goal is to position India as a leader in quantum technology.

Key Objectives of the Mission

  • Development of quantum computing, communication, sensing, and materials/devices.

Quantum Computing Initiatives

  • Qubit Development: Plans to develop 20-50 qubits in 3 years and reach 50-100 qubits by year five.
  • Focus on enhancing qubit coherence and refining error correction techniques.
  • Establishment of specialized labs with cryogenic systems for research.
  • Aim to boost scientific research capabilities via complex quantum simulations.

Quantum Communication Goals

  • Development of Quantum Key Distribution (QKD) for highly secure communication, previously tested by ISRO and DRDO.
  • Creation of a national quantum communication network to secure both national and international data transmission.
  • Engagement in technological advancements, including quantum repeaters, to expand quantum networks beyond current limits.
  • Emphasis on applications in defense and government sectors, prioritizing security in communications.
