Such technologies for transferring consciousness from one brain to another are already being conducted in secret laboratories. Let's remember the MK-Ultra program, which was conducted by the CIA. In a nutshell: in this program, "zombification" and personality substitution took place with the help of psychotropic substances and hypnosis. The program was super-secret, and after it was so classified that it was officially declared closed. Such experiments were conducted in many countries, including the USSR. And it began, at least officially so it is known, with Nazi Germany.
Of course, you won't find official information in open sources, and as for closed sources – I can't refer to documents. Therefore, I will give general information – where and what. Although this general information already indicates that work is being carried out and, of course, the results are classified. Even within the framework of preserving know-how. You understand the advantage of this. If you perform cloning and transfer consciousness there.
Here's an example from public sources.
The Human Brain Project (HBP) is a large human brain research project founded in 2013 in Geneva, Switzerland. The project involves hundreds of scientists from 26 countries and 135 partner institutions. The HBP project is unprecedented in its scale and the largest in the history of human brain research, with a budget of 1.6 billion dollars.
Similar projects have been launched in the US (BRAIN Initiative), China (China Brain Project) and Japan (Brain/MINDS).
Scientists have been able to transfer human consciousness (though not completely) into a computer. Now researchers are trying to upload human consciousness not only into a computer, but also into another human organism.
There is a lot of information about such works, conducted in the USSR, already in open sources. In her interviews and partially in her book "Brain Magic and Labyrinths of Life" academician Natalya Bekhtereva tells about such works carried out in secret research institutes in the USSR. Back in the days of the Soviet Union, being a secret communicator, I myself knew about such works directly from telegrams marked "top secret". And from negotiations – even more "frank" information. Here I should specify that I heard similar and more incredible information in negotiations, of course, in a closed network, not from the military, but directly from the employees of secret research institutes, because I was at the facility where they were testing new types of weapons. And the scientists talked about everything they were working on. So, according to them, this technology in the USSR was developed by a secret academician, who after an unauthorized test on himself died. There was, of course, and another version, which was put forward by colleagues: the academician transferred his consciousness into a younger employee, and made his body dead. A brilliant alibi.

Now let's get to the fact that the reality of what we are going to speculate about is taken on faith. We do, after all, believe in the atom, god, dark matter, the human soul, and many such things. Or at least partially in any of these and similar things.
So believe that there is everything in infinity. And do not forget my main postulate: if you said "not everything", it means that you have presented a minuscule part of this eternity. Therefore I declare that these parallel worlds really exist, moreover – they are an exact copy of ours. I will cite quantum teleportation as proof. Since not all my dear readers understand subtleties of this process, I will make detailed explanations.
