# Step 1: Create a quantum circuit with 3 qubits and 2 classical bits
qc_sender = QuantumCircuit(3, 2)

# Step 2: Create an entangled Bell pair between qubits 1 and 2
qc_sender.h(1)  # Apply Hadamard gate to qubit 1
qc_sender.cx(1, 2)  # Apply CNOT gate with control qubit 1 and target qubit 2

# Step 3: Prepare the quantum state to be teleported on qubit 0
qc_sender.x(0)  # Example: Apply X gate to initialize qubit 0 in |1⟩ state

# Step 4: Entangle qubit 0 (sender's qubit) with qubit 1
qc_sender.cx(0, 1)  # Apply CNOT gate with control qubit 0 and target qubit 1
qc_sender.h(0)  # Apply Hadamard gate to qubit 0

# Step 5: Measure qubits 0 and 1 and store results in classical bits
qc_sender.measure(0, 0)  # Measure qubit 0 into classical bit 0
qc_sender.measure(1, 1)  # Measure qubit 1 into classical bit 1
