GHZ state
Learn GHZ state in Q# with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.
GHZ state is an atomic Q# topic inside Quantum Patterns. The example below uses the actual construct named by the lesson rather than a generic placeholder.
Focus on what GHZ state changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.
Topic-specific example
operation GHZ(qs : Qubit[]) : Unit { H(qs[0]); for i in 1..Length(qs)-1 { CNOT(qs[0], qs[i]); } }
Track qubit state changes carefully and reset allocated qubits before release. Measurement changes the state and cannot be treated like ordinary logging.
