Context:
India to Launch Quantum Satellite for Quantum Communications: NQM is a Department of Science & Technology program aimed at accelerating the use of quantum physics for advanced communications and sensing systems.
Highlights:
- The National Quantum Mission (NQM) is a government of India initiative to develop quantum technologies and make India a leader in quantum research and innovation.
- The NQM was approved by the Union Cabinet in April 2023 at ₹6,000 crore, with the planned quantum satellite as part of this package.
Quantum Satellite
- Quantum satellite is a communication satellite which utilizes quantum physics in its security.
- Quantum computers can easily destroy the prevailing techniques that protect messages; however, quantum physics also gave a path to protection.
Security of Messages
- Encryption:
- Encryption task conceals the information behind a term, called a cipher.
Cryptographic Security works on a principle hiding secret code behind a complicated mathematical problem.
- Encryption task conceals the information behind a term, called a cipher.
- The most advanced encryption standards in current use may be broken with future quantum computers.
