What is the significance of the experimental satellite of quantum science launched by China?
Real quantum communication is independent of time and space by using quantum entanglement theory. In that case, the communication between us and Mars will not be seriously delayed, nor will it be affected by intermediate objects such as weather. At present, this so-called quantum communication satellite hardly uses any quantum theory, but only changes the encryption mechanism a little. An expert will laugh at it.
And how can China make real quantum communication civilian? If quantum communication is really popular, how can other countries monitor us? Other governments will have no incentive to do so. On the contrary, if quantum computing is popularized, it will be subversive, and its difficulty is several orders of magnitude higher than that of quantum communication. In other words, real quantum communication is just a "fragment" of quantum computing.
China's quantum satellites are called quantum encryption satellites at most, and have nothing to do with quantum communication satellites. Just defrauding the state funds.
