China Launched World’s First Hack-Proof Communication Satellite

On Tuesday, China successfully launched the world’s first quantum satellite which brags of establishing “hack-proof” communications between space and the ground as it is equipped with security features to avert wiretapping and intercepts.

The program is a priority as President Xi Jinping has urged China to establish itself as a space power, and apart from its civilian ambitions, it has tested anti-satellite missiles.

The satellite was launched from the Jiuquan Satellite Launch Centre in the remote northwestern province of Gansu at 1:40 am.

The 600-plus-kilogramme satellite will circle the Earth once every 90 minutes after it enters a sun-synchronous orbit at an altitude of 500 kms.

The satellite will enable secure communications between Beijing and Urumqi, Xinhua said, referring to the capital of China’s violence-prone far western region of Xinjiang, where the government says it is battling an Islamist insurgency.

It is nicknamed “Micius,” after a fifth century BC Chinese philosopher and scientist who has been credited as the first one in human history conducting optical experiments.

In its two-year mission, the Quantum Experiments at Space Scale (QUESS) is designed to establish “hack-proof” quantum communications by transmitting uncrackable keys from space to the ground and provide insights into the strangest phenomenon in quantum physics – quantum entanglement.

Quantum communication boasts of ultra-high security as a quantum photon can neither be separated nor duplicated.

It is hence impossible to wiretap, intercept or crack the information transmitted through it. A quantum key is formed by a string of random numbers generated between two communicating users to encode information.

Once intercepted or measured, the quantum state of the key will change, and the information being intercepted will self- destruct.

With the help of the new satellite, scientists will be able to test quantum key distribution between the satellite and ground stations, and conduct secure quantum communications between Beijing and Xinjiang’s Urumqi.

QUESS, as planned, will also beam entangled photons to two earth stations, 1,200 kms apart, in a move to test quantum entanglement over a greater distance, as well as test quantum teleportation between a ground station in Ali prefecture in Tibet, and itself.
