What is entangle?

Entanglement is a phenomenon in quantum mechanics where two or more particles become connected in such a way that their properties are intertwined and correlated with each other, regardless of the distance between them. This means that if one particle is measured or manipulated, it immediately affects the other, even if they are separated by large distances. Entanglement is one of the most peculiar and mysterious aspects of quantum mechanics, and has been explored for its potential applications in quantum computing, quantum cryptography, and quantum teleportation. It also challenges our classical understanding of physics, as it suggests that the nature of reality might be more interconnected and non-local than we previously thought.
