Researchers have explored two methods for estimating entropy in multi-qutrit quantum systems: variational quantum algorithms (VQAs) and classical convolutional neural networks (CNNs). For smaller systems (up to three qutrits), VQAs showed that accuracy is mainly dependent on the number of trainable parameters. For larger systems (two to five qutrits), a CNN trained on measurement outcomes demonstrated accurate and stable predictions, with performance improving as system size increased. This CNN approach required significantly fewer measurements than full state tomography and proved robust to noise. AI
