Chinese scientists managed to be the first to create a quantum key distribution. The technology was used on a quantum satellite which transmitted a message to the ground. What was special about this operation was that the code had a potentially impenetrable nature. This breakthrough could rebuild the entire global communication network with the security of data as a priority.
The Unhackable Message Reached Two Points at Various Distances from the Satellite
On Thursday, the academic journal Nature published the recent achievement that the Chinese team of scientists unlocked thanks to their Quantum Experiments at Space Scale. This is the first satellite in the world that works on quantum technology. The equipment was dubbed as ‘Micius’ which is the name of a Chinese scientist and philosopher from the 5th Century B.C. This historical character was the first person who conducted optical experiments.
The lead scientist of the project, Pan Jianwei, stated that the 1300-pound satellite managed to send encrypted messages to several ground points. These were located in the Chinese regions of Xinglong and Nanshan. Therefore, the distance between the receptor and the quantum satellite itself varied from 400 miles to 745 miles.
The Quantum Satellite Offered a Window of Opportunity above China of 10 Minutes
The moment the satellite orbited over China, it created the perfect window. However, this opportunity lasted for only 10 minutes, so experts had to move fast. This was when the 300 kbit quantum secure key was generated and then sent to Earth. Nonetheless, this is enough time to deliver important bank data or make a safe phone call.
Today’s technology might have answered a lot of problems, but it also generated a new kind of threat, namely cyber hacking. Therefore, privacy has become a crucial mission for most companies. Many scientists started developing a quantum computer.
On the one hand, this technology is perceived as a threat. That’s because such a computer could easily penetrate security layers of the traditional computers. On the other hand, quantum mechanics is viewed as the safest vault for information.
