W state example¶

W states are another way to entangle three qubits, and do so differently than GHZ states.

a W state circuit.

Open in IBM Quantum Composer

Read why W states are considered have more robust entanglement than GHZ states in the W states vs. GHZ states section of the Entanglement topic.
