For questions about the principle and application of quantum entanglement. It is a physical phenomenon which occurs when pairs or groups of particles are generated, interact, or share spatial proximity in ways such that the quantum state of each particle cannot be described independently of the state of the other(s), even when the particles are separated by a large distance—instead, a quantum state must be described for the system as a whole.

Is it possible to have entanglement between more than two qubits?
There is entanglement of formation and entanglement that can be distilled, but the question of how to measure the entanglement of more than 2 qubits is an ongoing area of research. … Yes, you can have three-qubit entanglement. For example, the GHZ state (like the Bell states, complete correlation among the qubits) or the W state. …
