Scalability Issues in Quantum Computing: Strategies and Solutions for Large-Scale Systems

Abstract

Quantum computing represents a transformative leap in computational capability, promising solutions to complex problems that are intractable for classical computers. However, the field faces significant scalability challenges, particularly as systems scale to larger qubit counts and more complex algorithms. This paper explores the major scalability issues in quantum computing, including qubit connectivity, error rates, and decoherence. We also discuss various strategies and solutions for addressing these challenges, such as quantum error correction, advanced qubit architectures, and hybrid quantum-classical algorithms. The goal is to provide a comprehensive overview of current research and future directions in making quantum computing practical for large-scale applications.
