First of all, quantum communication involves quantum motion in the quantum field. The first one is about quantum communication, which involves a quantum movement in the quantum field. Then, using these quantum movements to spread information or data will be 10 times, 20 times or even 100 times faster than the 5G network we are using now. Just like this, China has made a new breakthrough in the quantum field, so in the future quantum field, it is likely to be used as a new generation of communication tools and information dissemination methods, and it may also be used as a communication information in the future universe.
Second, quantum communication, its speed may not exceed the speed of light. As for quantum communication, its speed may not necessarily exceed the speed of light, because the speed of light is the fastest movement mode known to mankind at present. A movement of about 300,000 kilometers per second takes only one second to circle the earth. You can imagine how fast this speed is, and it is exactly so. Now, the study of light beam is still in depth.
Third, I believe that one day humans can make objects comparable to the speed of light. Finally, maybe one day humans can make objects comparable to light beams. At this speed, we can travel in the universe.
