Non Hackable Quantum Computing proved. First Quantum Encypted video conference hold between two continents

We are now standing at the verge of an era where everything is possible.

While we still remain little far but we have already started to move in the realms of the weird world called Quantum Computing. The world’s first intercontinental quantum link is now real because it led scientists to held a long-distance video conference on September 29 between Austria and China. In order secure the whole prcess of communication, a Chinese satellite distributed a quantum key, a secret string of numbers which can be used to encrypt the video transmission so that no one could intercept or hack on the conversation. In the call, chemist Chunli Bai, president of the Chinese Academy of Sciences in Beijing, spoke with quantum physicist Anton Zeilinger, who is the president of the Austrian Academy of Sciences in Vienna.

Apart from talking, the also used a technique known as quantum key distribution, to share secret strings of numbers while ensuring that no hacker can intercept the code undetected. Those quantum keys are then used to encrypt information sent via traditional internet connections. Decoding the transmission requires the same key used during time of encryption.

Scientists also exchanged images by using a process which is meant to be uncrackable.All of this had been possible due to China’s Micius satellite, which launched in 2016, used lasers to beam photons, or light particles, to ground stations on Earth. Micius sent a series of photons encoding a string of 0s and 1s to a ground station near Beijing. The satellite stored information about the sequence until it reached a station near Vienna, where Micius beamed down another string of photons. Then using the advanced methodology, the satellite combined the two sets of numbers and relayed the message to both stations to allow them to create matching keys.
