QUESS Satellite: Important Topics for UPSC Exams
QUESS Satellite: Important Topics for UPSC Exams
What is QUESS?
- QUESS stands for Quantum Experiments at space scale.
- It is an international research project in the quantum physics jointly developed under Chinese-Austrian Satellite Mission
- The satellite is nicknamed “Mozi” or "Micius," after a Chinese scientist who conducted ground-breaking optical experiments in the 5th century B.C.
- QUESS is the first spacecraft launched capable of generating entangled photons in space.
What is the Mission of QUESS?
- It is a proof-of-concept mission designed to facilitate quantum optics experiments over long distances to allow the development of quantum encryption and quantum teleportation technology.
Which is its importance?
- As per Xinhua, QUESS will send messages to ground stations using entangled photons, such a system is theoretically impossible to hack.
- In addition, any attempts to snoop would be picked up via an induced change in the photons' state.
- The project tests a technology that could one day offer digital communication that is hack-proof
- It could be the future of wireless communications and set new standards in internet security.
- If QUESS is successful, further Micius satellites will follow, allowing a European–Asian quantum-encrypted network by 2020, and a global network by 2030.
- As per some scientist, QUESS has enormous potential in the defence industry.
