First, the quantum micro-world is very huge, and the transmission speed is faster than our real world. First of all, the first point is that in the quantum microscopic world, the propagation speed of matter is very fast, which can be close to the existence of light speed, and the light speed can reach about 300 thousand kilometers per second. If we humans assume that we can spread by quantum one day, then we can send more substances to farther places, which is an important development project for us in future scientific research. It's just that a science and technology of human beings hasn't deeply understood and explored quantum theory.
Second, the transfer of substances should also take into account another restrictive factor. Secondly, there is another point that other restrictive factors should be considered in the transmission of materials, such as the influence between propagation speed and propagation space. After all, we have no in-depth research and development on quantum communication. What is the limiting factor in the quantum world? We humans don't have a clear definition yet.
Third, how do we realize teleportation? The last point is how to make quantum teleportation, which is a difficult problem that puzzles many scientists. After all, it is difficult for us to move instantaneously between substances now, not to mention a development prospect in the quantum field.
