This chapter explains two categories of quantum communications technologies: quantum random number generation and quantum networking (or ``quantum internet''). If the quantum networking necessary to achieve the ideal of a quantum internet were achieved, one could likely use the technology to connect disparate, small quantum devices into a larger cluster computer, or connect multiple quantum computers together to create a larger quantum computer. The chapter sets the stage for interest in quantum communications by briefly explaining the rise of signals intelligence (SIGINT) capabilities of governments and the proliferation of these powers to non-governmental actors.
