China's quantum satellite breaks record for delivery distance of quantum entrap photosChina’s new spacecraft Micius, will be a spy satellite that can help scientists with unbreakable secret communications channels. This technology will make use of quantum physics.  Micius was first launched from the Gobi Desert that uses the technology of establishing a quantum link between particles placed 1200 kilometers away around the Earth. They’re needed to distribute the particles or photons of light from satellite-to-ground-station that can encrypt the “keys” to secret messages across the quantum communication network. Additionally, it can be used to develop protocols for secure cryptography along with immediate teleportation of quantum information and to link together local quantum internet fiber networks.

Professor Chao-Yang Lu from the University of Science and Technology in Hefei, China said, “Our goal is to link together local quantum internet fiber networks. Today, we made use of mathematics to protect our networks but henceforth quantum network will be protected by the laws of physics.” “It will be ultra-fast and ultra-secure”, he further added. Quantum technology should work in such a way that will keep our financial data private online. It’ goes one step further to hide the sensitive data using quantum science. “This is the first distribution of quantum from a satellite, setting a new distance record,” said, Professor Zeilinger.

When sensitive data is shared between two parties over the internet, it should use the complicated encrypted number that is used to scramble the subsequent characters. It should also contain the key that will allow the other person to encrypt the decrypted data. The uncertainty property of quantum particles allows people engaged in secret communications to know if they are being secretly followed.

Mechanism of quantum satellite:

The satellite comprises a quantum-enabled transmitter that splits photons and a single packet of light into two entangled photos. In quantum physics when photons are entangled, one particle immediately reacts with its pair that is been placed at an infinite distance. While launching the quantum satellite, two beams of entangled photons were fired at separate ground stations. By performing the Bell test, the physicists came to know that photons had reserved quantum entanglement.
