Quantum Entanglement

“Quantum entanglement is like a bit coin that funds the universe in terms of interaction and information. It’s a sort of magic sauce that connects together all objects in the universe in terms of light.”

 It’s the central principle of quantum physics, though highly misunderstood. In the simplest terms, it can be stated that it is the linking of multiple particles together in such a way that the measurement of one particle in quantum state determines the possible quantum state of all the other particles. These tangled particles are just not limited to pairs, in 2014 approximately, 500,000 particles were entangled artificially. This connection isn’t dependent on the location of particles.  Changing one particle will surely induce a change in the other particle. Even if it appears to transmit information instantaneously, it doesn’t actually violate the classical speed because there’s no movement through space. It has been demonstrated experimentally with photons, neutrinos, electrons, molecules as large as bulky balls and even small diamonds.

The Einstein–Podolsky–Rosen paradox or EPR paradox is the best known example of quantum entanglement. The paradox involves two particles that are entangled according to quantum mechanics. According to the Copenhagen interpretation of quantum mechanics, each particle is in an uncertain state until it is measured. Before measurement, only the probability of it existing in certain states can be calculated. when it is measured, the state of that particle becomes certain. in case of entangled particles, when the state of one particle is measured, the other particle’s state also becomes certain. This is bending minds for decades, because it breaks one of the most fundamental laws of universe that the information transferred between two particles cannot occur faster than light, yet it does!
