What is the News?
Scientists from the Space Applications Center and Physical Research Laboratory have used quantum entanglement to create a hack-proof communications system.
How was the hackproof communication system achieved?
Scientists used the real-time Quantum Key Distribution(QKD) to conduct hack-proof communications between two places separated by 300 meters.
They created a channel to share secure text, image transmissions and two-way video calling.
With this demonstration, India is getting ready for satellite based demonstrations of fundamental quantum mechanics experiments as well as quantum communication for future-proof data security.
What is the Space Applications Center (SAC)?
SAC is one of the major centers of the Indian Space Research Organization(ISRO).
Purpose: It focuses on the design of space-borne instruments for ISRO missions and the development and operationalisation of applications of space technology for societal benefits.
The applications cover communication, broadcasting, navigation, disaster monitoring, meteorology, oceanography, environment monitoring and natural resources survey.
Located in: Ahmedabad, Gujarat
What is Physical Research Laboratory(PRL)?
It was founded in 1947 by Dr Vikram Sarabhai. It is a unit of the Department of Space. It carries out fundamental research in selected areas of Physics, Space & Atmospheric Sciences, Astronomy, Astrophysics & Solar Physics, and Planetary & Geo-Sciences.
Located in: Ahmedabad, Gujarat
Terms Mentioned in the Article
Heisenberg’s Uncertainty Principle: It was articulated in 1927 by the German physicist Werner Heisenberg. According to this principle, it is impossible to know the exact velocity of a particle, and its exact position, at the same time. One can calculate velocity, or position, to precision, but not both at the same time.
