Concept: Quantum communication boasts ultra-high security communication. It uses subatomic particles to securely communicate between two points.
In case intruder (hacker) tries to crack the message in Quantum communication, it will change its form in a way that would alert the sender and cause the message to be altered or deleted.
Justification: Statement 1: Earlier, researchers around the world had successfully sent quantum messages on land. But this first of its kind satellite-based quantum network would make it possible to send quickly encrypted (hack proof) messages around the world. It also opens door to other possible uses of the technology. The launch is also a major triumph for China in the field of quantum technology.
Statement 2: It is not related to research in quantum physics as a separate focus. It will be located in sun- synchronous orbit and help bolster China's communication system.
The QUESS satellite has been nicknamed as Micius after a 5th century BC Chinese philosopher.
