+To adapt and enhance the code for predicting new drug combinations in humans and handling Æon outcomes in a Kaggle notebook for the mentioned competition, you can make the following modifications:

+
+In this adapted version:
+- The number of drugs to combine is set to 3, and the number of qubits needed to represent the combinations is calculated using `bin(num_drugs_to_combine - 1)`.
+- The quantum circuit is modified to create combinations of drugs using controlled-NOT gates.
+- The fidelity of the quantum state is calculated using `state_fidelity` to assess the quality of the quantum state.
+- The rest of the code remains similar to the previous versions, including data preprocessing, model training, prediction, evaluation, and visualization.
+
+Please note that this is still a simplified example, and you would need to adapt it to your specific quantum computing scripture and healthcare dataset.
