Talk Title: A Categorical Perspective of Encoding Real-World Data in Quantum Computers
Series: MHI Physics Joint Seminar Series
Abstract: The question of how to encode real-world data in quantum computer has a tremendous amount of importance in the quantum machine learning (QML) community. There are a few proposed metrics to quantify the efficacy of quantum feature maps with the most used criteria being 'expressibility' [1] and 'expressivity' [2]. However, as noted by the authors, there are shortcomings with these two techniques. Our empirical analysis of using the standard schemes of angle encoding, instantaneous quantum polynomial encoding (IQP), and amplitude encoding to perform machine learning tasks on different dataset reveals new insights into our metrics need to be considered when choosing a particular quantum encoding technique [3,4]. Using the perspective of category theory, we propose that quantum encoding techniques should preserve "structures" of classical data. Based on this insight, we proposed technique on comparing the entropy of a point-cloud against the analytic extension of von Neuman entropy applied to quantum operators [5], directly addressing one area of structure.
