China’s Micius satellite distributes secret key for quantum communication to Austria

Through satellite-to-ground secure key distribution, a secret key was created between the two countries at locations some 7,600 km away from each other. During the experiment, scientists transmitted images between the two countries, and a 75-minute video conference was successfully held between Beijing and Vienna. Traditional public key cryptography risks being hacked, while quantum key technology, used in quantum communication, eliminates the possibility of wiretapping and secures the communication.
