Quizzes for review
A quantum state of three qubits which has the following shape: |W⟩=1/√(|001⟩+|010⟩+|100⟩). It is remarkable for representing a specific type of multipartite entanglement and for occurring in several applications in quantum information theory.

W state
In our experiment we prepared a W state |W⟩ = (|001⟩ + |010⟩ + |100⟩)/√3 and verified its robustness to qubit loss.
