Quantum entanglement is the phenomenon of quantum states of two or more particles, and the two are phenomenal. In other words, we learn to observe for the quantum state of one of the particles. Find out if the others are part of it. In order to understand more clearly, let's examine the concept of spin once more.
Think of a card, you have a picture on the top, but you do not have that picture on the bottom. We need to take a full tour in order to be able to see the card from the picture again, so this card is the spini 1. Now I draw the same picture on both the top and the bottom of the same card. Things are different at this point, the card to see the picture. We do not have to turn it a half times, we turn half a turn and see the same picture again. At that time the spine of this card was 1/2.
We have a system where two quantum states collide with each other. When we observe one of these particles, we can say that the other particle is spin down at the same time (without time difference) if the observed particle is spin up. So even if there are kilometers between particles in this system, they interact with one another and we interact with other particles. This is actually a teletransport example! If there was a distance of 10 light years between the two particles, we would not have had any effect on the two parts of the ball we were moving at the speed of light, but it would take 10 years, but we can suddenly act on two particles in quantum circulation.
But do not be happy immediately. Although it seems possible from the theoretical point of view, we are still very far to make a Tardis, to beam objects. Because the quantum entanglement only gives us the ability to transmit quantum information (information). Nevertheless, quantum entanglement is a new subject in physics and studies continue to work on it.
