Quantum Computing: Vision and Challenges

Abstract

The recent development of quantum computing, which makes use of entanglement, superposition, and other quantum fundamental concepts, has the ability to provide substantial processing advantages over traditional computing. These quantum features help solve many hard problems that cannot be solved with traditional computing methods. These problems are in areas like modeling quantum mechanics, logistics, making chemical-based advances, designing drugs, statistical science, sustainable energy, banking, reliable communication, and quantum chemical engineering. The last few years have witnessed remarkable advancements in quantum software and algorithm creation as well as quantum hardware research, which have significantly advanced the prospect of the realization of quantum computers. It would be helpful to have comprehensive literature research on this area to grasp the current status and find outstanding problems that require considerable attention from the research community working in the quantum computing industry. To better understand quantum computing, this paper examines the foundations and vision based on current research in this area. We discuss cutting-edge developments in quantum computer hardware advancement, and subsequent advances in quantum cryptography, quantum software, and high-scalability quantum computers. Many potential challenges and exciting new trends for quantum technology research and development are highlighted in this paper for a wider debate.
