Abstract

This paper explores the potential of quantum computing for probability density estimation (PDE), a crucial component of many machine learning algorithms. Traditional PDE methods often struggle with high-dimensional data, leading to computational bottlenecks and potentially inaccurate estimates. We propose a novel approach leveraging quantum circuits to perform PDE, capitalizing on quantum phenomena like superposition and entanglement to accelerate and potentially enhance the estimation process. Specifically, we outline a quantum algorithm designed to approximate probability density functions (PDFs) directly from data samples. The core of our approach involves encoding data into a quantum state and utilizing quantum gates to perform calculations related to the PDF. Furthermore, we address the challenges of noise inherent in quantum systems through the integration of quantum error correction techniques. This work lays the theoretical groundwork for a quantum-enhanced PDE method, demonstrating the feasibility of significantly improving estimation speed and accuracy for complex datasets. We focus on the conceptual design and potential benefits of this approach, without performing actual experimental validation.
