The quantum world is like a ghostly place. A lot of that scariness is due to something called entanglement that's when two particles become mysteriously linked.
Quantum entanglement is a physical phenomena that occurs when pairs of particles are generated, interact or share spatial proximity in ways such that the quantum state of each particle cannot be described independently of the state of the others, even when the particles are separated by a large distance.
When you measure some property like spin of one particle, you automatically know the spin of its partner will be, even if that other particle is on the opposite side of the universe.
Let's understand this phenomena by simple example.
Imagine each particle is a coin. Spin those coins on a table. Will they land heads or tails, we do not know. Similarly a particle spin is a mystery until you measure it. Now let's assume these coins become entangled. They are still spinning and finally one lands. We see that it's head. Now you know that the other coin whenever it lands will be tails guaranteed. The coins or particles aren't communicating. One does not call up the other one and tell it to land tails instead they are like two parts of a whole with a shared history and a mysterious inexplicable cosmic connection. That is the magic of quantum entanglement.
Physicists have been exploring how to use entangled particles to build powerful computers. Some scientists think that such a long-distance connection has more fundamental importance. Quantum entanglement may serve as the thread that stitches space together. Researchers studying mathematical models of the universe have found that cutting the link between previously entangled particles is like tearing apart the fabric of space-time.
The first ever image of entanglement -
The Physicists captured an image of quantum entanglement for the first time. Scientists from the university of Glasglow shared the first known image of a bell entanglement. The picture depicts two photons interacting and sharing physical states for a brief instant, an event that occurs regardless of the actual distance between the particles.
