Quantum communication uses subatomic particles, photons, to transmit data using the principles of quantum mechanics.
The researchers were able to make the first quantum secure video call between the Chinese Academy of Sciences and the Austrian Academy of Sciences.
Call and data transfer was carried out with the help of a satellite called Micius.
The President of the Chinese Academy of Sciences Bai Chunli made the world’s first Intercontinental quantum video call to chat with Austrian physicist Anton Zeilinger, Professor and author of numerous works in the field of quantum teleportation.
The mechanism of quantum communication is as follows. Satellite Micius sends entangled photons at two stations in Austria and China. The photons are encoded using so-called polarization as a security check. Scientists make measurements of polarization and then sent back to the satellite your measurements. Then the satellite creates the security keys that you can use to encrypt and decrypt data contained in the video call.
Note, quantum communication uses subatomic particles, photons, to transmit data using the principles of quantum mechanics. This means of communication is considered the safest, since such particles cannot be destroyed, duplicate, or track. Ways to hack into these messages has not yet been found.
