Definition of Quantum Entanglement
Quantum entanglement refers to a phenomenon in quantum mechanics where two or more particles become interconnected in such a way that the state of one particle instantaneously influences the state of another, regardless of the distance separating them. This correlation persists even when the entangled particles are separated by vast distances, leading to what Einstein famously called "spooky action at a distance."
In essence, entangled particles exhibit properties that are inherently linked. For example, measuring the spin of one particle will determine the spin of its entangled partner, even if they are light-years apart. This non-local characteristic of entanglement challenges classical intuitions about separate entities and thus acts as a cornerstone for understanding quantum mechanics.
