From Distributed Quantum Computing to Quantum Internet Computing Understand the future of the internet with this accessible guide Quantum computing, which draws upon the principles of quantum mechanics to perform computing functions unrestricted by the binary language of ordinary computing, has developed with extraordinary speed in recent years. Progress in quantum computing and its related technological subfields, including quantum internet, has been rapid enough to suggest that we are living in a “new Quantum Age.” To understand the future of the internet, it’s now essential to understand the present and future of quantum computing and quantum internet computing. This book provides a groundbreaking overview of this field of technology and its latest developments. It provides readers with a working knowledge of the key topics required to connect quantum computing to the future of distributed computing and the internet, including important issues like quantum protocols, distributed quantum computations, fundamental computations in the quantum internet architecture, and more. The result is an accessible and essential reference for any reader looking to better understand quantum technologies. From Distributed Quantum Computing to Quantum Internet Computing readers will also find: Detailed discussion of topics including qubit states, entanglement, quantum gates, and more. Mathematical background for underlying key concepts. Worked out examples that aim to initiate readers into the emerging area of quantum internet computing. This book is ideal for researchers and graduate students in quantum computing, quantum internet, quantum communications, and related fields, as well as Computer Scientists and Information Technology students and researchers who want an introductory overview to quantum internet computing.

As quantum computers advance rapidly, traditional encryption methods are becoming vulnerable, making it essential to explore fundamentally new communication technologies such as the quantum internet. The quantum internet is a revolutionary technology that uses the principles of quantum mechanics to transmit data securely and quickly. Unlike classical networks, quantum networks use quantum entanglement and quantum key sharing (QKD), thus providing a higher level of security against future cyber threats. This article presents the technological foundations of the quantum internet, the architecture of quantum networks, and the infrastructure challenges, including quantum repeaters and network scaling. We also discuss industrial applications of the quantum internet, with a focus on the financial, government, and healthcare sectors. The quantum internet is still under development, but it is expected to become a new standard for communication in the coming decades. The study highlights the technological readiness and practical potential of the quantum internet, pointing to a secure and scalable future in communication networks.
