Description

This circuit prepares a GHZ (Greenberger–Horne–Zeilinger) entangled state across three qubits, then measures each qubit.

Qiskit Circuit Code

```python
from qiskit import *

# Create circuit with 3 qubits and 3 classical bits
qc = QuantumCircuit(3, 3)

# Prepare GHZ state
qc.h(0)
qc.cx(0, 1)
qc.cx(0, 2)

# Measure all qubits
qc.measure([0, 1, 2], [0, 1, 2])
```
