With the development of quantum technologies, the quantum internet has demonstrated unique applications beyond the classical internet and has been investigated extensively in recent years. In the construction of conventional internet software, the protocol stack is the core architecture for coordinating modules. How to design a protocol stack for the quantum internet is a challenging problem. In this paper, we systematically review the latest developments in quantum internet protocols from the perspective of protocol stack layering. By summarizing and analyzing the progress in each layer’s protocols, we reveal the current research status and connections among the layers. Our work provides readers with a comprehensive understanding of the quantum internet and can help support researchers focusing on a single layer to better define the functions that the layer should possess and optimize related protocols. This approach enables all layers to work better together based on an understanding of the other layers.
Quantum computing technology, both hardware and software, has witnessed significant growth recently because of research breakthroughs and industry developments. The swift pace of progress in quantum computing is due to a higher relative potential compared to its classical computing counterpart. Quantum computing has various advantages, including computational power, speed, and security. In the context of efficient communication, current quantum technology offers a glimpse into the future realization of a Quantum Internet (QI). Similar to the classical internet, a QI consists of interconnected layers; however, it differs by utilizing quantum principles, software, and hardware. This poster paper will discuss the primary layers of a QI, highlight the communication flow, and then conclude by identifying challenges in realization.
Breakthrough developments in quantum information technology is paving the way to the Quantum Internet. This article aims to provide an overview of the current state of research and development in the field of Quantum Communications and Quantum Internet. We examine the main building blocks and the latest achievements. By providing a holistic overview of recent achievements, this article fosters a deeper understanding of these building blocks, the related opportunities, and challenges associated with the realization of the Quantum Internet. We also provide some simple pedagogical models aimed to give the reader a clear insight on the interactions between quantum networking elements. A simple Quantum Internet 5Level-3D communication model is also provided, which integrates with, rather than parallels, the classical OSI and TCP/IP models. We further describe deployed testbeds and trials and highlight potential opportunities and challenges for Communication Service Provider's. We also provide some KPIs of quantum technologies and their evolution over the last decade. This article is intended as a self-contained entry level tutorial for newcomers who are not familiar with quantum information theory, but with some background knowledge about classical networking. Academics, students, as well as professionals can use this article to become able to begin researching the Quantum Internet, without having to read a plethora of articles, web pages, and books on the subject.
The rapid technological advances in the field of quantum communications and the arrival of quantum computers, with a sufficient number of qubits to break the most used encryption algorithms used to date will change the Internet paradigm, as we know it today. Research centers, universities, industries and governments are working hard on the development of more scalable and efficient quantum communications networks, as well as the standardization of protocols, processes and interfaces needed for its industrialization. Many are the definitions of what will be the quantum Internet of the future (its architecture and components), but we offer a more relaxed definition of this concept, so that it is already possible to have a primitive QI with the technology available today, but without all the functionalities and components that will have in the future. As an example, the Madrid Quantum Network meets the requirements of this basic QI, proving to be a first step towards more complex architectures and functionalities. In addition, this concept has direct application as an intranet in restricted military environments, where high levels of security are required and whose extension is limited to metropolitan areas.
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.
