China's quantum satellite transmits tangled photons into Earth for the first time

China's quantum satellite has succeeded in transmitting tangled photons with a distance of 1,200 km to the Earth with lasers, shattering the previous grainy record of 102 km.

Tangled photon particles have been transmitted to Earth from a distance of 1,200 km with a laser.

This is considered a breakthrough in the technology of absolutely safe information transmission.

According to scientists, the encryption method is now becoming obsolete due to the messages you send to your relatives and the top secret communication networks at risk of being exposed. While quantum communication technology is much safer and that is why researchers and governments are trying to find a quantum encryption method.

The Chinese researchers' announcement that quantum satellites transmit tangled photons with a distance of 1,200 km has opened up bright prospects for quantum information .

Quantum entanglement allows particles in different locations to have the same quantum state, according to Pan Jianwei, who participated in the study. You can imagine a single particle but can exist in many places, as if they were able to separate themselves. Quantum particles - usually using light particles (photons) - is a great way to send safety information, because 'eavesdropping', interfering with the communication will change the state. The quantum of the particle, the receiver will immediately know that the transmission line has been interrupted by external effects.

In August last year, China launched its first quantum satellite orbit called QUESS. It marks the first milestone in the ambition to build a network that cannot be "hacked by hackers" from China and hopes that by 2030, the system will go into official operation. QUESS satellite is the 8-year research result of quantum scientist Pan Jianwei and space engineer Wang Jianyu.

Professor Anton Zeilinger, who currently teaches in Vienna, Austria, the QUESS satellite for the first time demonstrates that quantum signaling on a global scale is entirely possible and this is an important step in opening the era of quantum Internet Future.
