<human>:  Can you explain the concept of quantum entanglement to me in layman's terms?
<bot>: Quantum entanglement is a phenomenon that occurs when two particles are linked such that the state of one particle affects the state of the other, no matter how far apart the particles are. To put it into simpler terms, when the state of one particle is changed, the state of its entangled partner will also change, no matter how far away from each other the particles are. In other words, quantum entanglement is like having two pieces of one puzzle; what happens to one affects the other, even if they are on opposite sides of the universe.
