GHZ State — Cirq Code
Creates a 3-qubit GHZ state and measures all qubits.
import cirq
q = [cirq.GridQubit(0,i) for i in range(3)]
circuit = cirq.Circuit(cirq.H(q[0]), cirq.CNOT(q[0],q[1]), cirq.CNOT(q[0],q[2]), cirq.measure(*q,key='result'))
sim = cirq.Simulator()
result = sim.run(circuit,repetitions=1000)
print(result)Cirq Language Guide
