Skills and knowledge needed to leverage quantum computing in big data.

 

Introduction

Quantum computing represents a paradigm shift in computational power, offering unprecedented capabilities for processing vast datasets. Unlike classical computing, which relies on bits (0s or 1s), quantum computing leverages qubits that can exist in superpositions, enabling parallel computations at scales unattainable by traditional systems. For big data applications, where volume, velocity, and variety pose significant challenges, quantum computing promises transformative solutions. This chapter explores the skills and knowledge required to effectively harness quantum computing in big data contexts, spanning theoretical foundations, technical expertise, and practical applications.
