Can real time communication in the universe be achieved by quantum communication? Why?

The goal of real-time communication in the universe is really impossible to achieve through quantum communication. Because, although the speed of quantum entanglement reaches the "over-distance" effect; However, humans do not fully receive the information that comes with quantum transmission.

As we all know, quantum mechanics is one of the most important disciplines in the frontier physics of the 21st century, and currently plays a key role in all aspects of society. Whether it is the mobile phone or computer that we use in our daily life; At present, the advanced encryption technology of all countries in the world depends on the breakthrough of quantum technology.

In 2017, the Chinese Academy of Sciences announced that we had reached a new breakthrough in the field of quantum communication, which can achieve real-time information transmission between the Earth and the Moon. Subsequently, in the same year, NASA in the United States also claimed that they had made "exciting progress" in quantum communications. The data shows that the project carried out by the United States can achieve "migratory transmission" in a short distance.

It seems that the application of quantum mechanics in the field of communication is really incredible. I believe that many people have envisioned the so-called "real-time communication of information in the universe". When quantum mechanics is mature enough, will we be able to transmit information at will in any corner of the universe and arrive instantly?

Just kidding, of course it's impossible. Can so-called "quantum communication" really be transmitted in real time? Again, the answer is no.

First of all, many people mistakenly believe that the transmission of quantum information is "instantaneous", which may be due to the misunderstanding of over-distance speed. That's right, the speed of quantum entanglement is indeed beyond time and space, almost "teleportation".

However, according to the special theory of relativity, the information received by a human observer is capped at the speed of light. That is, no matter how fast we can transfer the information;

However, the speed of light still restricts humanity's ability to recognize it. Unfortunately, quantum mechanics will not help us achieve this great goal.

As for the whole universe that can be completed using quantum communication, one of the mediators of quantum communication is a quantum in the microcosm. Because one of the speed of propagation and movement of the quantum is beyond the speed of light as we currently know it.

It can be achieved. According to the theory of quantum entanglement, if quantum communication is realized, then real-time communication can be carried out anywhere in the universe according to this characteristic.

No, because quantum communication has not yet been scientifically proven to work in the universe. Now quantum communication is still in the hands of a few countries, and no one knows whether it can be applied in the universe.

Yes, because quantum communication is the topic of current research by scientists, and if this communication can be realized, then the level of secrecy will be greatly increased.

It is indeed the case, although the quantum communication technology is not yet perfect, but scientists have found a particularly peculiar phenomenon, that is, no matter how far the two quanta are, as long as the formation of quantum entanglement, then one side changes, the other side will also change, that is, the two quanta can maintain real-time dynamic change information reception, if this communication technology is really perfect, then in principle, it is really possible to achieve real-time communication in the universeAnd there is no delay, this sounds very dreamy phenomenon, scientifically speaking, it can be explained, and it can also benefit all our human beings, in fact, from a practical point of view, if we really achieve a technological breakthrough, then the benefits that can be brought to us are as follows:

1. Communication in vacuumI believe everyone has heard of the implementation of the U.S. moon landing program, which is in a vacuum on the moon, and the astronauts' communication can only rely on electronic communication at this time, and the signal of electronic communication may be affected in general, but if quantum communication technology is realized, then this impact will be completely canceled, which will bring great convenience to communication in a vacuum state.

2. It is more convenient to explore the universeAs we mentioned above, quantum communication technology is the principle of quantum entanglement, which can not only realize communication technology, but also realize real-time perception of changes, which will be more convenient for us to explore the universe, for example, if human technology has reached the point of launching spaceships into space at will, then the communication between a group of spacecraft can be perceived in real time.

It's true, because quantum is still magical, and as long as quantum can remain dynamic, then information can be accepted at any time.

Yes. Because quantum communication technology does not require a propagation medium, and the communication distance is very long, it really allows us to achieve real-time communication in the whole universe.

Technology is advancing rapidly, and I believe that time will prove everything.
