Abstract
Quantum machine learning (QML) is a promising field that explores the applications of quantum computing to machine learning tasks. A significant hurdle in the advancement of quantum machine learning lies in the development of efficient and resilient quantum classifiers capable of accurately mapping input data to specific, discrete target outputs. In this paper, we propose a novel approach to improve quantum classifier performance by using a data re-uploading strategy. Re-uploading classical information into quantum states multiple times can enhance the accuracy of quantum classifiers. We investigate the effects of different cost functions, such as fidelity and trace distance, on the optimization process and the classification results. We demonstrate our approach to two classification patterns: a linear classification pattern (LCP) and a non-linear classification pattern (NLCP). We…
