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.
