QUANTUM ENTANGLEMENT

QUANTUM ENTANGLEMENT



Where the distance does not matter.

Have You Ever Met your  Entangled Life Partner? 

Brief background:
Entanglement is a strange and weird phenomenon in quantum mechanics. Literally entanglement means non-separability. Mathematically, it's origin is rooted to superposition principle. The concept of entanglement stemmed from the historically famous thought experiment of Einstein, Podolsky and Rosen called EPR paradox, who/which tried to disprove the completeness of wave function without introducing the concept of Hidden variables. Ultimately, work of another mind John S Bell disproved the existence of hidden variables and proved the existence of quantum entanglement by virtue of Bell's theorem and inequality. Subsequently, experimental verification of the the quantum entanglement emerged.

What is this Quantum Entanglement?

It is a phenomenon in quantum physics where the quantum states of the entangled particles remain always connected so that actions performed on one affect the other, irrespective of their distance of separation.  Albert Einstein called it "spooky action at a distance." The physically different entities behave as a single as if they are non-separable always irrespective of their separation distance. You disturb one, other one will be disturbed almost instantaneously no matter where they are.
This is demonstrated experimentally using properties of particles like spins, position, momentum, and polarisation states. The rules of quantum physics state that an unobserved photon exists in all possible states simultaneously but, when observed or measured, exhibits only one state.
The photons can be separated by a large distance, hundreds of miles or even more.

What does it mean? 
Quantum entanglement property of particles are finding innovative applications for quantum communication at terrestrial level, satellite level and interstellar level beyond light years separation. Healing technique like Reiki is made use of this entanglement.
Also, we can think of a entanglement within family members. We heard about sometimes our mothers telling us about what happened to my children instantly is felt to me by way of hair rising (tu chungba), incidental thumb hitting an obstacle (khudi thiba), reflex pulses of eyes and beats (mit chongba, mihun chongba). All these are subtle forms of quantum entanglement at sub-consciousness mind.

Similarly, is there an entangled soulmate in someone's life! So called Made for each other! Where the distance doesn't matter to you!

All these are emerging areas of research using the concept of quantum entanglement. One day, science will crack and contribute to the human understanding!!!
