What is Quantum Entanglement?

When Einstein first heard of this phenomena his surprise was legendary and he called it “spooky action at a distance”. He used the phrase to refer to quantum mechanics, specifically, to entanglement, the idea that two physically separated particles can have correlated properties. Entangled particles remain connected, so any action performed on one (Even a simple measurement) will affect the other, instantaneously even when separated by billions of light-years of space

So let’s just say that there is a quantum particle here in Pune, India and I split this particle, keep one half here and transport another all the way in New York. I then change the direction of the spin in this particle here, the other particle, all the way across the world in New York simultaneously changes its spin, as if the information about the change in spin traveled faster than light to the other particle.

The entanglement of these particles means that the properties of any one particle cannot be described independently of the others, even when the particles are separated by a large distance – instead, they must always be described as a whole.

Modern scientists believe that this principle may not restricted to the quantum world but could be operating at the universal level too.

If this is indeed how things work, then does distance really matter?

Read our next article to know how the principle of Quantum entanglement is used in distance healing.
