Bell test example¶
The Bell test demonstrates that measurements of an entangled state cannot be explained by any local hidden variable theory, and that there must be correlations that are beyond classical.
Explore the Bell state further in the Entanglement topic.
GHZ state example¶
This circuit creates a GHZ state and then measures all qubits in the standard basis. The measured results should be half and half .
Read more about GHZ states in the GHZ states topic.
W state example¶
W states are another way to entangle three qubits, and do so differently than GHZ states.
Read why W states are considered have more robust entanglement than GHZ states in the W states vs. GHZ states topic.
