The burn-in code is implemented in the QuantumVM.measure_qubits() function. The function measures the given qubits and returns the results. However, it also applies a small amount of noise to the measurement results. This noise simulates the effects of decoherence, which is a major challenge in quantum computing.

Here is an example of how to use the burn-in code to create a quantum computer and execute a simple circuit:

Python quantum_computer = QuantumComputer(1, None)

Create a circuit that applies a Hadamard gate to the qubit. circuit = qiskit.QuantumCircuit(1) circuit.h(0)

Execute the circuit on the quantum computer. quantum_computer.execute_circuit(circuit)

Measure the qubit. results = quantum_computer.measure_qubits([0])

Print the measurement results. print(results)
