Context: Quantum Key Distribution system was demonstrated by DRDO and IIT Delhi scientists.

 

Details:

• For the 1st time in India, the Scientists from Defense Research and Development Organization (DRDO) and Indian Institute of Technology (IIT) Delhi successfully demonstrated the Quantum Key Distribution system.
• The technology displayed a Quantum Key Distribution link between Prayagraj and Vindhyachal in Uttar Pradesh; the distance between them was 100 kilometers.

 

Quantum Key Distribution:

• Quantum key distribution is a secure communication method involving components of quantum mechanics.
• It enables sending and receiving parties to produce a secret password known only to them.
• Secure Communication - Quantum key distribution allows the two communicating users to detect the presence of any third party.
• Quantum key distribution is only used to produce and distribute a key, not to transmit any message data. This key can be encrypted and then be transmitted over a standard communication channel.

 

Steps taken by the Government:

• The Union Government has inaugurated Quantum Communication Lab.
• Government is actively supporting indigenously developed Quantum Key Distribution (QKD) solutions.
• The Government has allocated $1 billion for the National Mission on Quantum Technologies.

 

Expected Outcome:

• It will help in making communication lines safe and secure.
• Open a new chapter in India’s growth
• Attract new start-ups in this sector.
• Support India’s claim of becoming a Superpower in the Science and technology field.
• Ensure safety of satellite communication lines.

 

Challenges:

• Low spending on Research - In India, Public expenditures on research have been stagnant between 0.6-0.7percent of GDP over the past 2 decades.
• Inadequate support of Private sector - In most countries, the private sector carries out the bulk of research. However, in India, the government is the primary source of research funding and primary user of these funds.
• State government support lacking - Government expenditure on Research is almost entirely by the central government.
• Lack of Skilled manpower in India.

 

Way forward:

• With this success, India has demonstrated indigenous technology of secure key transfer. It will help in establishing a safe and secure communication line for military and intelligence departments.
• This technology will allow security agencies to plan a suitable quantum communication network for ensuring safety and unity of the nation.
