Cơ bản về Quantum Computing

# Quantum Circuit cơ bản
from qiskit import QuantumCircuit, Aer, execute
from qiskit.visualization import plot_histogram
import matplotlib.pyplot as plt

# Tạo quantum circuit
qc = QuantumCircuit(2, 2)

# Áp dụng Hadamard gate
qc.h(0)

# Tạo entanglement với CNOT
qc.cx(0, 1)

# Measurement
qc.measure_all()

# Mô phỏng
simulator = Aer.get_backend("qasm_simulator")
job = execute(qc, simulator, shots=1024)
result = job.result()
counts = result.get_counts(qc)

# Visualize
print("Measurement results:", counts)
