👉 Entangledness is a mathematical concept in quantum mechanics that refers to the phenomenon where two or more particles are in a state of being "entangled" or interconnected, such that the state of one particle cannot be described without also knowing the state of another. This means that if one particle is in a state of being entangled with another, it can affect the other particle's quantum state, even though they are not directly connected to each other. For example, imagine two particles A and B,
