Abstract: A quantum version of an internet, called a quantum internet, is regarded as the holy grail of quantum information processing, enabling the deployment of a broad range of quantum technologies on a global scale. Given that the current internet has been expanded by connecting a new network to the Internet, it is essential for the quantum internet being expanded to have a standardized method for connecting small-scale self-organizing quantum networks. In this talk, we present a recipe that forms the basis of establishing such a standard method. This recipe is practical as it enables arbitrary clients to enjoy arbitrary quantum communication services faithfully and energy efficiently, independent of the whole size of the networks.
