from qiskit.quantum_info import *  # Import everything from quantum_info
from qiskit_aer import AerSimulator

# Create a Quantum Circuit with 2 qubits and 2 classical bits
circuit = QuantumCircuit(2, 2)

# Add a Hadamard gate to qubit 0
circuit.h(0)

# Add a CNOT gate between qubit 0 and qubit 1
circuit.cx(0, 1)

# Measure the qubits
circuit.measure([0, 1], [0, 1])

# Choose a simulator
simulator = AerSimulator()

# Compile the circuit for the simulator
compiled_circuit = transpile(circuit, simulator)

# Run the simulation
job = simulator.run(compiled_circuit, shots=1000)

# Get the results
result = job.result()

# Get the counts
counts = result.get_counts(circuit)

print("\nTotal counts are:", counts)

# Draw the circuit
print(circuit.draw())

In this example, we use IPython to interactively create, simulate, and visualize a simple quantum circuit using Qiskit. You can run this code snippet in the IPython shell or in a Jupyter Notebook.
