Can humans achieve "teleportation"?

In science fiction movies, we often see a person moving to another place instantly. If humans had this skill, they would no longer have to worry about traffic jams when commuting to and from get off work, and the congestion in Beijing would be completely eliminated. existence, there will no longer be any means of transportation. We can travel as we please, and the time spent on transportation is "0". This scene is not entirely science fiction. Now we have major breakthroughs in the field of quantum mechanical travel. Breakthrough, the information transmission speed of optical fiber network data has become faster, the distance has become longer, and "instantaneous movement" can be achieved in theory.

The teleportation we often talk about is actually the transmission of a single quantum state. We first need to entangle two single quantum particles with each other. The state of one particle will affect the other particle. Einstein put this This phenomenon is called "ghost-like super-distance influence." But this speed is limited. Looking at our physics, it is not difficult to find that even if instantaneous movement can be achieved, the fastest speed is infinitely close to the speed of light. It is impossible to travel around the universe at will. The picture below is the instrument used by scientists to realize the transmission of a single quantum state. Such a complex instrument can only realize the transmission of a single quantum state. The human body has 10 to the 30th power of particles, and each particle has its own energy state. To transmit these particles simultaneously in an instant is far more difficult than landing on the moon 10 times.

To achieve such instant movement, we need to arrange the entangled state of particles in advance, and the amount of data transmitted is also an astronomical amount. Assuming that we can transmit a person within ten seconds, it is equivalent to transmitting 10 30 bit particles within ten seconds. Many people may not have much concept of numbers. Let us use an analogy: to realize the "instantaneous transmission" of the human body "Move" is equivalent to our transmission speed of 10 G per second, which takes 300 billion years. This speed is obviously not instantaneous, and it is not as fast as using transportation.

To achieve true instantaneous movement, we need to transmit the quantum state of every particle in the human body. However, we currently cannot guarantee whether human consciousness will still exist after transmission. This is a difficult problem. Simultaneous transmission In the future, the reorganization of these particles requires the existence of a life-simulating structure. How to make this structure is also a big problem. If humans want to truly realize "teleportation", it will still take some time in the field of quantum mechanics. In addition to quantum mechanics, if humans want to achieve instantaneous movement, wormholes may be more possible.
