Our goal is to construct a universal quantum communication network testbed. These networks are one of the key technologies necessary for the realization of large-scale, distributed quantum computers (QCs). We will integrate hardware and software to demonstrate the principles and techniques of communication architecture and protocols, with the ultimate goal of practical implementation. This project's results will contribute not only to the development of large-scale, distributed quantum computers, but also the implementation of a quantum internet, helping make real the dream of a world where quantum information flows freely. We will proceed with a two-pronged strategy, which involves implementing and demonstrating the principles and technologies of the entire system on a small scale using the testbed, and validating scalability using simulations.
