5. Code Example

Here’s a simple example of a quantum circuit using Qiskit, a popular quantum computing framework:

from qiskit import QuantumCircuit, Aer, execute

# Create a Quantum Circuit
qc = QuantumCircuit(2)

# Apply a Hadamard gate to the first qubit
qc.h(0)

# Apply a CNOT gate (entanglement)
qc.cx(0, 1)

# Visualize the circuit
print(qc.draw())

# Execute the circuit on a simulator
simulator = Aer.get_backend('statevector_simulator')
result = execute(qc, simulator).result()
statevector = result.get_statevector()
print("Statevector:", statevector)
