The W state is a type of quantum state that is significant in the study of quantum information and quantum computing. Specifically, the W state is a kind of entangled state involving multiple qubits (quantum bits). It is known for its robustness in maintaining entanglement among particles. For a system of \( n \) qubits, the W state can be defined as: \[ |W_n\rangle = \frac{1}{\sqrt{n}} (|100...
